Notes from first ULI UK Tech Forum

1. We need to have a clear definition of technology. Physical as well as digital technology. Users and uses as well as creators and providers. Pre-construction, construction, post-construction. 

2. Because we’ve always had technology:

a. Writing (wooden stylus & wax tablet) movement

b. Air conditioning – occupancy

c. Underfloor heating – occupancy

d. The shower – personal

e. Bicycle – movement

f. Revolving door – occupancy

g. The elevator – occupancy

h. The car – movement

i. Solar panels – occupancy

j. The Internet – movement & occupancy

k. Autonomous vehicles – movement

l. Drones – movement

m. Photofungal trees – place
We’ve always had technology. It’s always changed. Perhaps the pace is accelerating globally (but we shouldn’t forget the industrial revolution). 

3. What hasn’t changed is the fundamental purpose of cities: social and economic trade. 

4. In the future, autonomous vehicles will change the nature of movement. They will permit people to be far more productive while they drive. 
5. Another key, and consequential, change will be in the nature of physical connections, transformed from highways to streets. Connectivity (as Chris Choa suggested) as an asset. 

6. Therefore the street as an asset. The piazza as an asset. Not just the buildings that line them. The suburban business park will go the way of the dinosaurs. 

7. The nature of online interaction is a further area of significant new change. 

A velvet revolution for the Blue House roundabout – Newcastle City Council to think again

Massive popular opposition to plans for a disfiguring roundabout leads to the City Council announcing this evening that it will go back to the drawing board. This is a positive development. A working group will now be established to look at alternative plans.

Growth. Are you old school or new school?

There are two different schools of thought about how to accommodate urban growth. The first says that cities should build more road capacity to handle private vehicle traffic. The second says that less space should be provided for private vehicles and more investment should be made in public transport and “active travel” i.e. walking and cycling. The first approach is generally more costly than the second.

The old school of thought has prevailed for around a century. The new school is relatively more recent, responding to the frequent failure of the former, where more road space has created more road traffic, which has created more congestion.

Cities all over the world are now removing expensive car-oriented infrastructure and introducing space for walking, cycling and public transport. Ring roads and bypasses are being unpicked and cities are thriving as a result. Look at Copenhagen, Paris, London, Birmingham, Boston, Poynton or any number of places that have employed the new school approach.

On Poynton…”This was the busiest junction in Cheshire, with 25,000 vehicle movements per day and the fourth worst performing retail centre in Cheshire East. It now accommodates a similar volume of traffic, but since average speeds have fallen to below 20mph, drive times through the centre are significantly reduced. Anecdotally people feel safer crossing the carriageway and cars will stop for them, make eye-contact and usually elicit a wave of thanks from the pedestrian.” The Academy of Urbanism

Road speeds are being reduced, from 40 or 50mph to 20 or 30mph. Not only on residential streets but at the intersections of major roads too. Why? Because when you slow traffic down it flows more freely. Why? Because at lower speeds, more vehicles can fit into the same space. This isn’t rocket science. It’s simply a different school of thought.

When a city pursues “old school thinking” of road capacity increases and banned turns then not only is this going to generate more road traffic it is also going to make it ever harder for people to do anything other than drive. In these circumstances, walking and cycling become harder. “Walking and cycling facilities” might be put in but these are often token gestures because they are fitted in around the needs of traffic. Desire lines – the paths that people prefer to take – are severed and people are encouraged to walk or cycle on unnaturally twisted journeys. What happens as a result? They don’t use these “facilities” and they take risky alternatives, dashing across road lanes or cycling among fast-moving traffic.

Old school thinking is voracious – once started it is hard to stop. Nevertheless, evidence, analysis and creative thinking can help. If there is a willingness to listen.

I speak from the perspective of practice – of having observed the behaviour of people on foot, on bikes and in vehicles in a scientific manner for over 25 years. Of having presented evidence of fact to local authorities and of overturning poorly thought-through, old school proposals. Of having designed alternatives that don’t put anyone in particular first but instead balance the needs of all. This isn’t about being pro-bike and anti-car. It’s about being pro-place and pro-cities.

And let’s be clear, new school thinking is fundamentally about being pro-growth. But pro a form of growth that is smart and sustainable: growth that doesn’t sacrifice the profound benefits of local places for the expedience of cross-city commuting, but growth that promotes alternative ways of traveling and enhances the attractiveness of cities as places to live in and invest in.

Backwards plans for Newcastle’s Blue House Roundabout

Newcastle City Council’s plans for the Blue House Roundabout are appalling and unnecessary.

I know the junction and have walked and driven across it more times than I can remember. The last thing it needs is what is proposed and I intend to do what I can to help stop the scheme.

There is already a significant body of local opposition to the proposals, for example:

“At present, it’s a busy, but functioning, junction occupying a particularly striking location – the intersection of two broad avenues of lime trees, some 130 years old, which cross the historic open spaces known as Duke’s Moor, Little Moor and the Town Moor. These spaces belong to the hereditary Freemen of Newcastle upon Tyne, who have been exercising their right to graze cattle here for a thousand years or so. They form a green belt around the city centre and make its inner suburbs surprisingly pastoral.”

Facebook and Twitter are both active:


Yet the more weight that can be brought against these unnecessary, expensive and car-centric proposals, the better.

Don’t let this nonsense be foisted any further. Take Newcastle forwards not backwards.

We are what we street. The elements of successful #urban placemaking

How the site fits into its context, including complementary and competitive attractions; in other words, what else is nearby to which the design should respond? The success of any development, no matter how large, is a function of the wider setting.

The specific points at which connections can be made into this context, including public transport connections; in other words the “gateways” into the design.

The spatial layout design of the project itself in terms of its streets and spaces, whether public/private or open/covered, and the importance of:

– first, encouraging through movement connections between gateways

– second, providing a simple, intelligible internal circulation network through a grid of streets and other connections.

This is the most important of the five elements since the spatial layout, once created, tends to be the most permanent part of the development. It is the most expensive to alter once constructed since it sets out the footprints of buildings and, importantly, since it carries the bulk of major services such as energy, water and data supply as well as waste handling.

Land use
The quantum of different land use attractions and the disposition of these within the spatial layout both in two and three dimensions; in other words where uses are and how they stack up, especially the land uses that occur at street level and any other principal pedestrian levels.

The location of land uses should follow the hierarchy of spatial connections created by the spatial layout design, with the most movement-sensitive land uses located on the most spatially important connections and so on. This alignment of land use attraction with spatial layout attraction is a fundamental property of both historic cities and successful modern places.

How the spatial layout is “dressed” both in terms of the “green/blue” landscape of planting and water and the “architectural” landscape of building frontages at the principal pedestrian levels.

Here what matters is that the spatial layout is not overly fragmented or dispersed by planting and that the principal pedestrian levels are lined with open, active frontages.

The five elements of successful placemaking establish a framework for design practice. What matters next is the way in which these generic principles are translated into a specific design proposal. This is a creative step, which relies on a blend of imagination and craft, honed by experience.

The challenge for future urban practice is that the five elements are not commonly appreciated in the field of retail development, which has instead adopted principles of gravitational attraction that tend to create anchored, inward-facing, covered malls rather than open, street-based shopping streets, whether we call such streets “high streets” or “souqs”.

It has been, and will continue to be, down to pioneering organisations to point out what is increasingly obvious to all but those who are too immersed in it: that anchored malls create sterile places; and then for these pioneers to deliver new places that work because they employ the timeless elements of successful placemaking.

Fortunately, this challenge is facilitated by the continued emergence of technology-based tools for analysing location, identifying points of linkage, testing different layout concepts and modelling the interaction of these with different land use and landscape treatments.

We don’t guess the structural performance of individual buildings so why do we guess the human performance of entire cities?

The structural steelwork of a large and complex building would not be designed without running engineering calculations. Even the smallest of buildings is subject to objective structural analysis. No client and professional team would rely on guesswork, no matter how famous or experienced the architect or engineer.

So why do we leave the human performance of places to the whim of architects who run no calculations and rely only on their instinct and ego? Why is the science of human behaviour so poorly developed? Why is chronic failure still tolerated?

In the early sixteenth century, William Harvey challenged the medical profession to take a more objective, more observation-driven approach to the understanding of the circulation of blood. At the time, medical thinking was largely based on the beliefs of Galen of Pergamon, who had set these out in the second century. Harvey challenged a medical mindset that hadn’t changed in one and a half millennia. And he encouraged his peers to embrace advances in science that allowed new forms of investigation.

We can see a similar state of affairs in the prevalence of, and institutional inertia around, twentieth century planning. Based on belief, not observation-based science, a doctrinal approach to urban planning and design pervades the professions. This is the case, whether the specific approach is Modernism, the Garden City movement or (and especially) Landscape Urbanism. Each is to some degree unscientific.

These approaches propose different kinds of urban outcomes but what unites them is a belief that the future should look fundamentally different to the form of continuously connected, dense and mixed-use urbanism found in cities for as long as there have been cities – the kind of urbanism that architects and town planners visit on their holidays.

The kind of urbanism – and here’s the irony – that Galen would have recognised. If only architecture and town planning were stuck in a fifteen hundred-year-old mindset. We would still have vehicles on the road but we wouldn’t have vehicle dominance. We wouldn’t have land use zoning that generates long-distance commuting, traffic congestion and negative health impacts. We wouldn’t be encroaching on the rural landscape with semi-detached, density-fearing dwellings.

Fundamental change in our professions is needed and science has an important part to play. In the spirit of Harvey’s observation-based approach, we need to embrace the new capabilities offered by sensing, analytics and modelling. We need to understand how cities truly work before we then form ideas about how to change them. We must move beyond the beliefs of twentieth century practice. The evidence is there to demonstrate that practice based on belief hasn’t delivered great places with the consistency required either by the investors in them or the users of them.

We can learn from Harvey, even if our end goal is the urbanism of Galen.
