25 Essential Town Planning Thought Leaders Globally (2026)

Last updated: June 2026

The most consequential decisions about how people live, how cities grow, and how communities absorb change are made by town planners. As of June 2026, more than 55 percent of the global population lives in cities, a figure projected to reach 68 percent by 2050 according to UN-Habitat. Every percentage point of that shift represents millions of people whose daily lives will be shaped by land use decisions, zoning codes, housing supply, transport infrastructure, and public space design. The people thinking most seriously about those decisions are not always the ones with the highest public profiles. They are researchers, practitioners, advocates, and content creators who have spent years building a body of work that is quietly reshaping the profession and the places it produces. This list brings together 25 of the most essential voices in town planning globally in 2026, selected for a documented contribution to the field through published work, practice, or research, and for active, current engagement in the public conversation. The voices here span land use reform, walkability, housing affordability, planning data science, equity and justice, placemaking, and planning systems reform across North America, Europe, Africa, the Global South, and beyond.

As of June 2026, the defining debate in town planning is no longer whether cities need to change. It is whether planning systems are capable of delivering that change fast enough. Housing affordability crises are reshaping political landscapes across the anglophone world. Zoning reform has moved from academic argument to legislative reality in dozens of jurisdictions. The profession is simultaneously reckoning with a workforce capacity crisis, a technology inflection, and a growing recognition that the Global South is where the most consequential planning challenges of the century will play out. The people on this list are engaging seriously with all of it.

Why Town Planning Matters Right Now

Town planning is not a technical backwater. It is the discipline that decides where housing gets built and who can afford it, which streets are safe enough to walk down, whether a new suburb will become a community or a car park with houses attached, and how much carbon a city will emit over the next fifty years based on the density and land use decisions made today.

The profession is under pressure from multiple directions simultaneously. The housing affordability crisis across North America, the United Kingdom, and Australia and New Zealand has made planning reform one of the most politically charged policy areas of the decade. Strong Towns has 290 or more local conversations across North America as of January 2026, a figure that reflects how deeply the conversation about urban financial resilience and incremental growth has penetrated mainstream civic life. The Royal Town Planning Institute represents more than 27,000 planning professionals in the UK alone as of early 2026, a number that understates the global scale of the profession.

At the same time, the tools available to planners are changing faster than professional education can absorb them. Open-source spatial analysis, machine learning applied to land use modelling, and real-time transport data are reshaping what is possible in planning practice. The people who sit at the intersection of technical rigour and public communication are doing some of the most important work in the field.

For a deeper look at the local government and council leadership context in which much planning happens, the post on thought leaders in council leadership globally covers the practitioners navigating planning from inside government. And for the broader urban planning and city leadership conversation, 

50 influential thought leaders in urban planning and city leadership globally covers the wider field. This list focuses specifically on town planning as a professional discipline, including land use, zoning, housing supply, walkability, placemaking, and planning systems reform.

How This List Was Compiled

Each person on this list was selected on the basis of a documented, fact-checked contribution to the specific discipline of town planning, including land use, zoning, housing supply, development control, walkability, placemaking, transport planning, and planning systems reform. Selection criteria included a published body of work, a substantive institutional role directly tied to planning practice or research, active and current engagement in the public conversation, and verifiable current incumbency in their stated role as of June 2026. The list deliberately surfaces voices doing active work in 2026, not only those whose reputations were built in earlier decades.

His work sits at the intersection of transportation planning, public health, and the built environment, and he brings empirical rigour to a field that has long relied on professional convention in place of evidence.

Planning Law, Policy, and Housing Reform

8. Helen Fadipe

BAME Planners Network

Helen Fadipe is the founder of the BAME Planners Network and served as President of the Royal Town Planning Institute (RTPI) for 2025. She is one of the most visible advocates for diversity and inclusion in the planning profession, building an organisation specifically designed to support and amplify the voices of planners from Black, Asian, and minority ethnic backgrounds within a profession that has been historically homogeneous.

Her presidency of the RTPI brought a distinctly inclusion-focused agenda to the most prominent professional body in UK planning, at a moment when the profession is actively grappling with both a workforce capacity crisis and a reckoning with whose interests and knowledge bases have shaped planning decisions. Her LinkedIn posting on planning culture, professional development, and representation has made her one of the most followed planning voices in the UK.

9. Victoria Hills

CIOB

Victoria Hills served as Chief Executive of the Royal Town Planning Institute for nearly eight years, departing in July 2025 to take up the role of Chief Executive Officer of the Chartered Institute of Building (CIOB). She holds a Master of Town Planning from Newcastle University, has worked for all three Mayors of London in various capacities, and led the establishment of the UK's second Mayoral Development Corporation at Old Oak and Park Royal before joining the RTPI in 2018.

Her transition to the CIOB reflects the deep connection between planning and construction in delivering the built environment, and she brings planning's perspective to a sector wrestling with quality, safety, and sustainability at scale. Her LinkedIn presence is consistently active on questions of the built environment, professional standards, and institutional leadership, making her a bridge between the planning and construction conversations.

10. Janette Sadik-Khan

Bloomberg Associates

Janette Sadik-Khan is one of the world's foremost authorities on urban transportation and the transformation of city streets. As Commissioner of the New York City Department of Transportation from 2007 to 2013, she oversaw the pedestrianisation of Times Square, nearly 400 miles of new bike lanes, seven Select Bus Service routes, and the launch of the largest bike-share programme in North America at the time. As a founding principal at Bloomberg Associates, she advises mayors around the world on city redesign.

In June 2026, Mayor Zohran Mamdani nominated her to the MTA Board to help advance his fast and free buses agenda. She chairs the Global Designing Cities Initiative, which implements people-focused street design standards adopted in more than 150 cities globally. She is the author of Streetfight: Handbook for an Urban Revolution and was named the 2027 recipient of the Seaside Prize, awarded for significant contributions to architecture, urban planning, and community development. She is featured in the 2025 documentary Changing Lanes.

11. Dan Parolek

Opticos Design

Dan Parolek is the founder and CEO of Opticos Design, one of the most active urban design and zoning consultancies in the United States. He achieved widespread recognition by coining the term Missing Middle Housing, which has become one of the most prominent planning frameworks of the past decade, inspiring legislative reforms at state and local levels across North America.

The Missing Middle Housing concept addresses the gap between single-family homes and large apartment buildings, naming and legitimising the duplexes, triplexes, fourplexes, townhouses, courtyard apartments, and cottage clusters that make neighbourhoods walkable, affordable, and diverse. Planetizen named Parolek among the 100 most influential urbanists. His LinkedIn output on zoning reform and housing choice is consistently practical and regularly engaged by planners and policymakers.

12. Jennifer Keesmaat

Jennifer Keesmaat Advisory

Jennifer Keesmaat served as Chief Planner of the City of Toronto from 2012 to 2017, leading one of the most complex planning departments in North America through a period of rapid growth. She has since built a profile as one of the most active and articulate planning advocates in the Canadian conversation, using LinkedIn as a primary platform for commentary on housing, density, transit, and the relationship between planning and political leadership.

Her posts consistently engage with the gap between what planning can achieve and what politics allows, making her particularly valuable to practitioners navigating the institutional realities of planning in democratically contested environments. She is among the most followed planning voices on LinkedIn in Canada and brings a practitioner's precision to public debate.

13. Joe Cortright

City Observatory

Joe Cortright is the Director of City Observatory, an independent policy institute focused on urban economic analysis, housing, and transportation policy. He also publishes CityCommentary, a Substack newsletter that has become one of the most closely read sources of urban economics commentary for planning practitioners and policy audiences in North America.

His work sits at the intersection of land use economics, housing markets, and planning reform, and he brings a rigorous, evidence-based lens to debates that are too often conducted at the level of assertion rather than analysis. His LinkedIn presence is active and engaged, and his willingness to challenge consensus positions in housing policy makes his commentary consistently worth reading for anyone working on zoning reform or housing supply.

Placemaking and Urban Design

14. Anthony Garcia

Street Plans

Anthony Garcia is co-founder and principal of Street Plans, and co-author with Mike Lydon of Tactical Urbanism: Short-Term Action for Long-Term Change (Island Press, 2015) and the forthcoming Tactical Urbanism: 25 Ways to Transform Your City (Island Press). He delivered a keynote at Urban Future 2026 in Ljubljana alongside Lydon, and has led workshops and projects in cities across North America, Europe, and Latin America.

His work translates the theory of human-centred city design into the practical mechanics of getting things done in streets, car parks, and vacant lots with limited budgets and political capital. The Tactical Urbanism framework he helped develop has been adopted by planning departments, community organisations, and city governments on every inhabited continent.

15. Taibat Lawanson

University of Liverpool

Taibat Lawanson is Professor of Urban Studies at the University of Liverpool and one of the most important voices in the global conversation on African urbanism and planning in the Global South. She brings scholarly grounding in both British and West African urban development to her work, with a research background that spans the formal and informal dimensions of planning in rapidly urbanising African cities.

Her work addresses informality, housing, governance, and the specific challenges of planning in rapidly urbanising African cities where formal planning systems often operate at the margins of actual urban development. Her active LinkedIn presence makes her one of the most accessible Global South planning voices to practitioners outside the African continent.

16. Helen Santiago-Fink

Independent researcher and consultant

Helen Santiago-Fink is a climate urbanist and researcher with extensive experience working with international organisations and city governments on the convergence of the circular economy, climate action, and planning. She appeared on the APA Trend Talk podcast in 2026, sharing insights drawn from her international practice on how planners can integrate climate adaptation and circular economy principles into spatial planning.

Her work represents an emerging frontier in planning practice, addressing not just how cities grow but how they metabolise resources, manage waste, and adapt to climate stress within the physical constraints of the existing built environment. She is an active LinkedIn voice connecting climate science to planning practice.

Planning Research and Data Science

17. Toni Griffin

Harvard Graduate School of Design

Toni Griffin is Professor in Practice of Urban Planning at the Harvard Graduate School of Design and the founder of urbanAC, a practice built at the intersection of urban justice, community planning, and equitable design. She works with cities that have long histories of spatial and social injustice, including Detroit, St. Louis, Chicago, Memphis, Milwaukee, Pittsburgh, and Philadelphia.

Her earlier roles as Director of Community Development for Newark and Vice President and Director of Design for the Anacostia Waterfront Corporation in Washington, DC gave her the practitioner grounding that animates her academic work. She is one of the most important voices connecting the history of race, planning, and spatial injustice to contemporary practice in American cities.

18. Petra Hurtado

American Planning Association

Petra Hurtado serves as Director of Research and Foresight at the American Planning Association, where she leads the APA's annual Trend Report for Planners. The 2026 Trend Report, the fifth edition of the series, identifies nearly 100 trends with the potential to significantly shape communities, and represents the most comprehensive annual synthesis of emerging planning practice in the United States.

Her role at the APA positions her at the centre of the profession's collective intelligence function, synthesising research, practitioner experience, and futures thinking into a resource used by planning departments and professionals across North America. She is an active presence in APA's public communications and podcast output, and a significant contributor to how the profession understands its own direction.

19. Christian Benimana

MASS Design Group

Christian Benimana is Principal at MASS Design Group and Director of the African Design Centre, a training programme based in Kigali, Rwanda, that develops the next generation of African architects and planners. His work sits at the intersection of design, public health, and community development, and he has become one of the most prominent voices arguing that the design and planning needs of Africa require African leadership and African knowledge systems, not imported frameworks.

MASS Design Group's work across healthcare facilities, educational buildings, and community infrastructure in Africa operates on the principle that design quality and social equity are inseparable from one another. His perspective brings a challenge to standard assumptions about what planning knowledge looks like and where it comes from.

20. Philip Harrison

University of the Witwatersrand

Philip Harrison is Research Professor in the School of Architecture and Planning at the University of the Witwatersrand in Johannesburg, South Africa, and one of the most important scholars working on spatial planning in the African context. He served as a member of South Africa's National Planning Commission from 2010 to 2015 and spent four years as Executive Director in Development Planning and Urban Management at the City of Johannesburg.

His recent research, including a 2025 article in a Springer Nature edited volume, addresses how spatial planning ideas originate, circulate, and get hybridised across African cities, questioning the assumption that planning frameworks developed in the global North translate smoothly into African urban contexts. He brings both practitioner depth and academic rigour to one of the most consequential planning challenges of the century.

21. Nestor Davidson

Harvard Graduate School of Design

Nestor Davidson is the Emma Bloomberg Professor of Real Estate at the Harvard Graduate School of Design, an urban law expert whose work addresses the complex dynamics between state and local governance in land use and planning. He appeared on the APA Trend Talk podcast in 2026 to discuss the adversarial relationships developing between state governments and local planning authorities, and the challenges of state preemption in housing and zoning reform.

His scholarship sits at the intersection of law and planning, examining how the legal architecture of governance shapes what planning systems can actually deliver. The question of state versus local control over land use is one of the defining fault lines of contemporary planning reform, and Davidson brings precise legal and institutional analysis to a debate that too often generates more heat than light.

Planning and Technology

22. Vignesh Swaminathan

Kimley-Horn

Vignesh Swaminathan is an urban planner and traffic engineer at Kimley-Horn in San Jose, California, and the creator of the @MrBarricade platform on TikTok and Instagram. As of April 2026, his content has reached 1.6 million TikTok followers with accessible, often irreverent explainers on roadway design, cycling infrastructure, pedestrian safety, and the Black Panthers' advocacy for crosswalks in Oakland.

His approach is deliberately accessible, using the aesthetics and formats of popular social media to bring planning and infrastructure topics to audiences who would never engage with a planning document or an academic journal. For practitioners frustrated by the gap between technical planning knowledge and public understanding, his work represents one of the most effective experiments in planning communication happening anywhere in the world.

23. Tom Sanchez

Virginia Tech

Tom Sanchez is a Professor of Urban Affairs and Planning at Virginia Tech and a contributor to the American Planning Association's Trend Report for Planners. He appeared on the APA Trend Talk podcast in 2026 discussing the rapidly evolving landscape of artificial intelligence in planning, reflecting on the unpredictability of the future and the need for planners to remain both cautious and open-minded about AI's role in the discipline.

His work addresses how technology, data, and computational methods are reshaping what planners can do and what they should be responsible for knowing. As AI tools proliferate in planning workflows, his perspective on the profession's relationship with technology is grounded in a longer view of how planning has absorbed and been changed by previous waves of technical change.

Planning Theory and Urban Economics

24. Alain Bertaud

NYU Marron Institute of Urban Management

Alain Bertaud is Senior Research Scholar at the NYU Marron Institute of Urban Management and the author of Order Without Design: How Markets Shape Cities (MIT Press, 2018), a foundational text for anyone seeking to understand the relationship between planning regulation, urban markets, and the spatial structure of cities. He has worked as a principal urban planner at the World Bank and has been involved in urban planning projects in cities across many continents.

His central argument, that market forces and planning regulation interact in ways that planners often fail to adequately account for, has made him both influential and controversial in a profession that has sometimes been reluctant to engage with economic analysis. His work provides a rigorous analytical counterpoint to planning traditions that prioritise regulatory control without attending sufficiently to how markets actually allocate urban space.

25. Ricky Burdett

LSE Cities, London School of Economics

Ricky Burdett is Professor of Urban Studies at the London School of Economics and Political Science and Director of LSE Cities, one of the world's leading urban research centres. He was the Chief Adviser on Architecture and Urbanism for the London 2012 Olympic Games and served as director of the Venice Architecture Biennale. His research focuses on the social and spatial dynamics of cities globally, with a particular emphasis on how urban form shapes social life and opportunity.

LSE Cities produces some of the most influential comparative research on global city development, and Burdett has built an institution that connects academic rigour to policy relevance at the highest level. For a bridging reference between the planning field and the broader city leadership conversation, see 50 influential thought leaders in urban planning and city leadership globally, which covers the wider urban leadership field alongside planning practitioners.

Notable Voices We Almost Included

The town planning field is broader and deeper than any list of 25 can represent. Several voices were close to inclusion but could not be verified to the source documentation standard required, or occupied a position that placed them just outside the scope of this run. Richard Florida (University of Toronto, Martin Prosperity Institute) remains the most widely read voice on cities and their economies, and his work on the creative class continues to shape urban economic strategy globally. Andres Duany and Elizabeth Plater-Zyberk, the co-founders of DPZ CoDesign and the Congress for the New Urbanism, established the intellectual architecture of New Urbanism that continues to inform planning practice. Carlo Ratti of the MIT Senseable City Lab is doing some of the most technically sophisticated work on smart cities and urban data available anywhere. Anne Hidalgo, Mayor of Paris, has demonstrated what political will can achieve in urban transformation at scale, from cycling infrastructure to the 15-minute city. Ed Glaeser of Harvard has made urban economics accessible to a general audience in ways that few academics manage. These voices and others are worth following and reading.

Common Mistakes to Avoid in Town Planning Leadership and Advocacy

The first mistake is treating planning as a purely technical exercise. Town planning carries enormous political weight, because it allocates space, value, and access in ways that benefit some people and cost others. The most effective planning practitioners and advocates understand this, and they engage with the political dimensions of their work rather than retreating behind professional neutrality. The people on this list are almost uniformly willing to take positions, make arguments, and accept that their work has distributional consequences.

The second mistake is recycling frameworks without testing their assumptions against local context. The 15-minute city concept, the Missing Middle Housing framework, the Tactical Urbanism toolkit, and the Strong Towns financial resilience model were all developed in specific contexts with specific assumptions about governance, land ownership, infrastructure funding, and community behaviour. Applying any of them in a different context without engaging with those contextual differences produces poor outcomes and, in some cases, actively harms communities that planning was supposed to serve.

The third mistake is treating the housing supply debate as settled. The evidence that restricting housing supply through zoning regulations increases housing costs is strong and growing. But the policy response is not uniform, and the tradeoffs between density, neighbourhood character, infrastructure capacity, and community control are real. The most useful planning voices, including Marohn, Bronin, Parolek, Speck, and Toderian, acknowledge these tradeoffs while still making the case for reform.

The fourth mistake is underinvesting in planning capacity. Sara Bronin's research and advocacy on the National Zoning Atlas, Petra Hurtado's work at the APA on foresight, and Geoff Boeing's development of open-source planning tools all point to the same underlying problem: most cities, and especially smaller cities and local authorities, do not have the planning staff, the data infrastructure, or the technical capacity to translate good intentions into good outcomes. The workforce dimension of planning is as important as the policy dimension, and it receives far less attention.

The fifth mistake is assuming that the Global South will simply replicate western planning trajectories. Philip Harrison's research on spatial planning in African cities, Taibat Lawanson's work on informality and governance in West African urban development, and Christian Benimana's practice at the African Design Centre all challenge the assumption that planning frameworks developed in North America and Europe are transferable to contexts where informal development, land tenure complexity, and governance limitations create fundamentally different conditions.

Many organisations find that international travel for facilitation is far more affordable than expected.

Implementation Guide for Engaging With Planning Thought Leadership

Reading the right voices is a starting point, not a destination. The question for any practitioner, policymaker, or organisation working in or around planning is how to translate exposure to thought leadership into changed practice.

The most effective approach is to identify one or two voices whose work directly addresses the specific planning challenge you face, and to engage seriously with their body of work rather than sampling surface-level content. Charles Marohn's work on the financial resilience of municipalities is most useful to people working on infrastructure funding and local government finance. Sara Bronin's work on zoning law is most useful to people engaged in planning reform advocacy or policy. Geoff Boeing's work on urban data science is most useful to planning departments with the technical capacity to adopt open-source spatial analysis tools. Matching the voice to the specific problem is more productive than building a general reading diet.

The second most effective approach is to engage with the platforms where these conversations happen in real time. LinkedIn has become the primary professional network for planning discourse, and several of the people on this list publish substantive original content there regularly. Strong Towns publishes daily. City Observatory maintains a Substack newsletter. The APA podcast provides regular access to researchers and practitioners across the discipline. Building a deliberate information diet from these sources keeps planning knowledge current in a way that textbooks and periodic conference attendance cannot.

The third approach is to look for opportunities to bring planning expertise inside your organisation rather than only consuming it from the outside. Jonno White works with leadership teams in organisations across the planning, local government, and built environment sectors, facilitating Working Genius workshops, team offsites, and leadership development programmes that help organisations build the internal clarity and collaboration they need to act on what they know. For more on team leadership in the local government context, see 40 essential local government thought leaders in Australia and New Zealand. To enquire about facilitation, email jonno@consultclarity.org.

The fourth approach is to pay attention to what is working in other jurisdictions. One of the most consistent findings across urban planning research is that cities learn most effectively from other cities rather than from national governments or academic institutions. Brent Toderian's consultancy work takes him from Auckland to Buenos Aires to Reykjavik precisely because the specific lessons of one city's planning experience can illuminate a different city's challenge. Investing in international exposure, whether through travel, international professional networks, or deliberately following voices outside your own planning system, compounds over time.

For the homebuilding sector specifically, which operates at the interface of planning regulation and construction delivery, the post on 35 influential homebuilding thought leaders covers the voices shaping the delivery side of the housing equation that planning makes possible.

Frequently Asked Questions

What is the difference between town planning and urban planning?

Town planning and urban planning refer to the same core discipline in most contexts, but the terms carry different connotations depending on geography and professional tradition. In the United Kingdom, Australia, and parts of South Asia, town planning is the established professional and statutory term, used in the name of the Royal Town Planning Institute, the Planning Institute of Australia, and most planning legislation in those jurisdictions. In the United States and Canada, urban planning is more common, though city planning, land use planning, and community planning are also widely used. For the purposes of this list, town planning refers to the professional discipline concerned with land use, zoning, development control, housing supply, transport, public space, and the regulatory frameworks that shape how cities and communities grow and change.

Who are the most influential town planners currently active in 2026?

Among the most influential actively working voices in town planning in 2026 are Brent Toderian (TODERIAN UrbanWORKS), Charles Marohn (Strong Towns), Sara Bronin (George Washington University), Jeff Speck (Speck Dempsey), Geoff Boeing (USC Price School of Public Policy), and Janette Sadik-Khan (Bloomberg Associates). Each brings a distinct perspective: Toderian on design and density, Marohn on financial resilience and incremental growth, Bronin on zoning law and reform, Speck on walkability, Boeing on urban data science, and Sadik-Khan on transportation and street transformation.

What is Missing Middle Housing?

Missing Middle Housing is a concept coined by Dan Parolek, founder of Opticos Design, to describe the range of housing types that sit between single-family detached homes and large apartment buildings, including duplexes, triplexes, fourplexes, townhouses, courtyard apartments, and cottage clusters. These housing types were common in many cities before mid-twentieth century zoning codes made them illegal in most residential areas. The term has become one of the most widely used frameworks in housing and planning policy across North America, inspiring legislative reforms at state and local level in jurisdictions from California to New Zealand.

What is the Strong Towns movement?

Strong Towns is a nonprofit organisation and movement founded by Charles Marohn that advocates for the development of financially resilient cities, towns, and neighbourhoods. Its central argument is that the post-war development pattern of North American cities, characterised by low-density suburban expansion, infrastructure-heavy land use, and highway-oriented mobility, creates long-term financial obligations that municipalities cannot sustainably meet. Strong Towns promotes incremental, affordable development, prudent infrastructure investment, and community engagement as alternatives to the growth-for-growth's-sake model. As of January 2026, Strong Towns has more than 290 active local conversations across North America.

How can a leadership team engage more effectively with planning reform?

Leadership teams in organisations affected by planning reform, whether as property developers, local governments, infrastructure providers, or community organisations, benefit most from clarifying their own decision-making frameworks before engaging with the complexity of planning policy. Jonno White, Certified Working Genius Facilitator and author of Step Up or Step Out (10,000+ copies sold), works with executive teams and boards to build the team clarity, trust, and communication that let organisations move from knowledge to action. Book Jonno for your next leadership offsite, Working Genius workshop, or facilitation session by emailing jonno@consultclarity.org.

Final Thoughts

Town planning is one of the most consequential and least publicly understood professions in the world. The decisions made by planners, researchers, advocates, and policymakers today about where housing gets built, how streets are designed, what zoning permits, and how cities adapt to climate change will shape where billions of people live and how they live for the next several decades.
