“The efficient, effective and responsible use of land is a goal that would be a win-win for all cities, their businesses and their citizens: the key question though is how cities can achieve this while quickly absorbing the significant increases in population that are flowing from the world’s continuing rapid urbanisation. Densification may be an obvious answer, but how to deliver successful densification is not so obvious and is one of the most important topics of this urban decade. Good density will mark out the next generation of winning cities.” Rosemary Feenan, Director of Global Research, JLL, and Chair, ULI Europe Policy & Practice
The Issue: Accommodating Population Growth and Economic Change. The main options. Allow Cities to Sprawl The world has turned against sprawl in theory.
It is too expensive in social , environmental, and public finance terms. But many cities continue to sprawl. People no longer want to do long commutes.
Build New Cities / Districts This is part of what is needed. In Middle East and China New Cities are emerging. But existing cities are key to accommodating most growth. Contain sunk investments and least mobile populations
Densify Existing Cities
Densifying existing cities appears to offer the best economic, social, and environmental returns for the least cost. Compact and polycentric cities can accommodate growth more quickly and flexibly. They also had greater long term flexibility.
The Density Diagram
The competitive advantage of density? “Most people do not understand that in certain situations density can be a wonderful thing. The concepts of density meaning proximity and convenience are not understood at all. Most people identify density with cramped spaces, a lack of greenery, and inconvenience. Education would be very helpful.” Dr Karima Nigmatulina, Executive Director, Master Planning Institute, Moscow
As the world get more urban and more dense human societies learn how to change and adapt. The societies that adapt to density fastest and most effectively will have an advantage. People in China have quickly become used to less personal space and to bumping into each other, they have adjusted quickly to density’. Sir Terry Farrell, Urbanist.
Drivers of Density “Sustainability is an important driver of density. Densification and more intense use of land produces buildings and infrastructure that are more energy efficient. Ultimately sustainable and denser buildings will provide a premium return and more affordable energy” Patrick Kanters, Managing Director Global Real Estate & Infrastructure, APG Asset Management “The densified city will produce a more liveable and sustainable reality that addresses the polarisation of income by providing shared amenities and spaces between people. Densification is the physical manifestation of the sharing economy.” Michael Spies, Senior Managing Director, Europe and India, Chair of Investment Committee London “It is not just urban population growth, but also smaller family units that is driving the need for denser cities and urban districts” Paul Lecroart, Senior Urban Planner, Paris Region “Employers who are looking to hire will always follow the talent. An out of town business park isn’t going to attract the best talent today. People want to be in lively and vibrant places, both at work and after work. This drives an intensification of urban centres.” Benjamin Lesser, Derwent plc

The term ‘density’ is related to many other terms that have distinctive meanings.
Density and Capital There is no doubt that the increasing importance of global flows of capital, people and information, and the nature of the city as a hub of investment of relatively few global players, has created an imperative in favour of densification. On the whole global capital investment opportunities flow to places which are accessible and visible – dense cities are these type of places. Prof Ricky Burdett, Professor of Urban Studies, Director, LSE Cities and Urban Age, London School of Economics and Political Science
“Capital facilitates ambition and aspiration in cities, it does not drive density but enables it. In the past capital sometimes got it wrong and invested in dense projects that failed before they came good due to poor planning, lack of infrastructure and facilities. Today, capital is not so stupid.” Andy Martin, Senior Partner, Strutt & Parker “Capital markets reward density with large scale investments. They like the scale and the pace of dense projects. They can exit sooner. The availability of large pools of capital that seek large, unified, and faster investment projects incentivises and stimulates density.” Chris Frampton, Managing Partner, East West Partners
Density and Infrastructure
Infrastructure Drives Densification
Density Finances Infrastructure.
Unlocks sites and enlarged scale of development.
Provides critical mass and value creation.
Increases connectivity and access.
Value can be captured and reinvested.
Enables mixed income and mixed use, services multiple functions.
Needs smart financial and planning
What do we mean by Density? Different Definitions

Doomed Density: memories, myths, and mixed feelings
Density Myths and Memories “Density is always about crowding poor people together.” “High density buildings attract crime.”
“Cities that become more dense lose individuality.” “People don’t want to live in high density buildings.” “You cannot combine low density and high density areas successfully within one city.” “Density always involves loss of privacy.”
“High density means high rise.”
Good or Bad Density? What have we learned? Bad Density
Mono use Mono income, age, ethnic Fast and unplanned Lacks infrastructure No adaptability No space Inappropriate to context Low design / ugly
Good density
Mixed Use Mixed income, age, ethnicity Incremental pace Infrastructure Flexible Open Space Between the buildings Amenities

Density: dividends for the economy, society and the environment
“By the late 70s and early 80s the world seemed convinced of the merits of high density development, and Hong Kong made an important contribution to this debate – showing that high density urban development could be successful with proper planning and efficient urban management. I am surprised that the density debate is still continuing!” - KK Ling, Director of Planning, Hong Kong Government

Who needs to lead the Density debate?
Three big challenges Despite the changing the attitudes to density, sprawl is still the dominant model of urbanisation. • Density and affordability. • Density and segregation. • Density and democracy.
“It is difficult to plan effectively for growth in a democracy which prioritises current preferences over future needs. Political process is always more attuned to those who have been here, versus those who would like to be, or those who have not yet arrived.”
“When given a choice, people make trade-offs between higher density and access to jobs and services like schools, hospitals and leisure facilities. Overcrowding within residential units affects attitudes towards neighbourhood density.”
Michael Spies, Senior Managing Director, Tishman Speyer.
Prof Ricky Burdett, Professor of Urban Studies, Director, LSE Cities
An agenda for advocacy, demonstration, and public education. i. Increase evaluation of city densities across the world and catalogue the ingredients of success. ii. Identify whether a global density benchmark can be developed to protect land from urban sprawl. iii. The training of planners, urbanists, to be bolder and more effective in planning for density. iv. Support for city leaders to learn how to promote density. v. Mount and disseminate demonstration initiatives that reveal how density works for liveability. vi. Support for long term planning that delivers for the future citizens and not just for the present preferences.
The Quest for Density
More than anything we need a renewed focus on demonstration projects, public education and the training of development professionals associated with density. It is clear that density is, in most cases, the best way to accommodate economic change and population growth providing the optimal returns for society and environment whilst also creating value that can be captured and shared, and making our cities more flexible. But the world does not yet know how important densification is or how it can best be achieved. Therefore we must commit ourselves to meeting this gap in knowledge and skills and to a new generation of advocacy, education, and inspiration about density.
