2. Human density

Featured image

This article is part of the series 25 building blocks to create better streets, neighbourhoods, and cities. Read how design, departing from the human dimension contributes to the quality of the urban environment. Follow the link below to find an overview of all articles.
 
Human dimension means that residents nor visitors feel overwhelmed by the environment. An urban planner must avoid them thinking that it is all about other things, such as commerce, traffic, or the buildings themselves, which unfortunately often is the case indeed. Constructions by 'star architects' can be crowd pullers but usually also result into a disproportionate use of space. Cities therefore better tolerate only a limited number of such edifices. Alexander Herrebout (OTO Landscape) believes that space has a human dimension if you experience attention for you as a human being and that there are objects you can connect with. For many, this will be more often a historic building (church, town hall) than a modernist one.

Compactness (‘enclosure’)

Compact streets and squares give a sense of security. They encourage people to linger there, increasing the chance of unforeseen encounters. Sjoerd Soeters considers squares in the first place as a widening in the street pattern and therefore they are preferably no larger than 24 by 40 meters. A round or oval shape enhances the feeling of security. If the height of the surrounding buildings is also in line with this, there may be contact between residents and people on the street. Good examples are the square he designed in the Oostpoort shopping center in Amsterdam, but also a square in <em>The Point</em>, a new shopping center in Utah (US), resp. bottom left and bottom center and of course the Piazza der Campo in Siena.

If streets are too wide or narrow or buildings are too high?

Trees, for example a double row all around, will help if a street is too wide or a square is too big. Trees are also a source of reducing urban heat. The extent to which trees contribute to the sense of intimacy is expressed by comparing the images at the top left (Herring Cove Road, Halifax, Canada) and the top right (Course Mirabeau, Aix-en-Provence). A square or a street that is too wide can be further visually reduced by the construction of terraces, the placement of a pavilion or the presence of water features, such as on the Brusselplein, Leidsche Rijn (bottom right). Sometimes also by allowing destination traffic and public transport.
A street that is too narrow can be widened psychologically by designing sidewalks and a carriageway in the same level and shades, possibly separated by a narrow band, as illustrated in the image of the Sluisbuurt in Amsterdam (top center).
If case of high-rises, the human dimension can be respected by planting trees and by placing taller buildings back from the plinth to limit their visibility from the street.  This is also illustrated by the image of the Sluisbuurt (top center).

Density

Compactness presupposes a certain density. In a very dense city center is only room for pedestrians and not for traffic, in some cases except for the tram. Though, these areas must be always accessible to emergency services. Waste removal, deliveries and parking must be solved differently, for example on the inner space of blocks or by introducing strict time slots. Every city also needs space for events such as concerts, fairs, etcetera. Accessibility is more important than a central location.

1. Lively streets and squares

Featured image

This article is the first in the series 25 building blocks to create better streets, neighbourhoods, and cities.Read how lively places contribute to the quality of streets and squares. Follow the link below to find an overview of all articles.
 
The public space is like a stage. The Dutch architect and urban planner Sjoerd Soeters, known for the Amsterdam Houthavens, likes to say that. He meant that it is the inhabitants and visitors of cities who provide the liveliness, but that streets and squares must ensure that they come. This apparently worked out well on the Rue Sainte-Catherine in Bordeaux (photo above right).

Shopping facilities and catering

Research shows that the quality of the shopping facilities, also for 'fun shoppers', is still the main driver to visit the center of cities. A varied catering offer follows in second place (photo bottom left). A welcome addition are spaces with a non-commercial purpose, such as museums, galleries, art lending, information centers of municipalities or companies, etcetera.

Sidewalks

Sidewalks use to be too narrow, due to the perceived need to accommodate motorized traffic. A sidewalk in central parts of the city must be at least 20 feet wide, such as that of Fillmore Street, San Francisco (top left photo). In that case, sufficient space is offered for greenery, free passage for passers-by and tables or chairs, billboards, and street vendors, who make a welcome contribution to the liveliness of the street.

Opportunity to rest

Places that invite you to linger increase the attractiveness of the area and the chance of unforeseen encounters (collision spaces). These can be terraces, but also non-commercial places such as tree-lined squares with benches, games, buskers (acoustic), an ice cream cart etcetera. One of the most famous examples is the Spanish Steps in Rome. Such spaces usually arise 'by themselves', but they can also be designed as such, for instance, squares in Barcelona and Shanghai (photos bottom center and bottom right). By no means it is certain that they will also be used as such.

Minimize traffic noise

In the more centrally located parts of a city, a certain level of sound is part of the experience, but traffic noise is a source of nuisance and drives away visitors. Through traffic is not compatible with all other (inner) urban functions; destination traffic must be reduced, channeled and its speed limited. Noise at events must also be reduced to an acceptable level for visitors, residents, and passers-by, knowing that events attract many people, but can also repel others as well.

Places with a different character

In an atmospheric city center you will find quiet places and others where it is bustling at the same time. Those quiet places can be small parks with playgrounds and benches to rest, but also publicly accessible courtyards of residential blocks.

Exploiting iconic places

Most cities have places with special characteristics. These are often historic or modern buildings, monuments, fountains etcetera. Sometimes it is a well-known square, such as the Vrijthof in Maastricht. Sometimes it is also the boulevard along a river or special viewpoints (photo top middle) that both city dwellers and visitors like to include in their route and where they linger for a while.

Art

All parts of a city with a central function should be amply supplied with art. For this purpose, also (temporarily) empty shops can be used, which also serve as an information center. Think of art objects on the street (possibly replica’s) and fascinating paintings on blind walls, which number must be limited by the way. In the evening, light art can be imagined on the facades of buildings surrounding streets and squares.

New series: 25 building blocks to create better streets, neighbourhoods, and cities

Featured image

This article is the introduction to the series 25 building blocks for better streets, neighbourhoods and cities, which you can read every Tuesday and Friday starting next week. The link below refers to an overview of all upcoming posts.

It often strikes me how much people agree about the quality of the living environment. Many, especially younger ones, prefer a house built in the '30s. Older neighbourhoods almost always score higher than modern ones, due to the alleged lack of atmosphere, sociability, and intimacy in the latter. Urban planners, architects and politicians would like to change this, and they are doing so. Slowly.

In urban planning a breeze of fresh air comes in.

How cities in Europe currently look stems largely from the ideas of Le Corbusier through his role in the Congrès Internationaux d'Architecture Moderne (CIAM). The Dutch architect and urban planner Cornelis van Eesteren was also a prominent representative. The influence of the Congress is visible in the spacious post-war residential areas with their long rows of single-family houses and medium-rise buildings. The underlying idea was to design a functional city in which living, working, shopping and recreation all have their own separated places.

Slowly, the voice of a new generation of urban planners in which Jane Jacobs and Jan Gehl (pictures above) play a prominent role became louder. They detest post-war urban expansion and advocate mixing urban functions.  70 years after the publication of her book The Death and Life of Great American Cities, Planetizen magazine predicated urban activist Jane Jacobs as the most influential urban planner ever, even though she never studied this field. Jan Gehl, who did, follows in second place. By the way, Anne Hidalgo, the mayor of Paris, is in 7th place; not because of what she studied but of what she put into practice.

Many others, including representatives of New Urbanism, play an important role in further developing the ideas of Jacobs and Gehl. For instance, they put back on the agenda the return to the 15-minute city. ‘New urbanists’ also top the list: Andres Duany, the author of Suburban Nation at four and Jeff Speck, who authored Walkable City, at ten.

The concept of high-quality living environment

Many contemporary ideas about urban development come together in the concept of high-quality living environment. A compact definition of this concept is improving human well-being in a condensing city. I have collected and clustered references to characteristics of high-quality living environments in many recent publications into 25 building blocks. Each block deals with one aspect of the quality of the living environment, or in other words the creation of better streets, neighbourhoods, and cities. Consider this a tribute to the mission of the Amsterdam Smart City community, of which I was a curator for several years.

I hope you get inspired and support the use of these building blocks.

How to live with global warming larger then 3 degrees C

Featured image

In my previous post (in Dutch) I summarized the main conclusions of the IPCC's Final Report: The probability that the world will have warmed by more than three degrees by 2100 is much greater than that we hold it at 1 1/2 degrees Celsius. In this post I will discuss the consequences of this for the world, whether there is still a way out and what the consequences are for Dutch policy.

Upcoming disaster

Featured image

Everyone should read the latest IPCC report. Current global policies are heading for a global warming of 3.2% in 2100. Although we have to continue emphasizing the necessity of radical policy change, at the same time, we must do more to mitigate the consequences of this increase in temperature.
I have made a short summary of the report (in Dutch), to be downloaded below
