Enriching design practice by the mapping of human behaviour patterns could transform urban space
An article published in the Architectural Review on 30th April 2018.
There’s much debate about how to measure density – dwellings per hectare, bedrooms per hectare or people per hectare; including or excluding major highways, parks and open spaces; the permanent population only or the transient one too?
While this gives urban planners something to disagree about, it risks missing the point: great urban places are not created by density; they’re created by intensity. The difference matters. When people describe the buzz of a market they don’t say, ‘Wow – it was so dense’. They’re much more likely to say how intense it was. Density is a word used by planners. Intensity is a word that real people use, and perhaps because it describes the outcomes that people experience rather than the inputs that have gone into creating them. It’s the outcomes that are ultimately more important.
But planning professionals like density. Even though density doesn’t capture the essence of what it feels like to be somewhere, the term appeals to professional instincts. It describes the raw ingredients that planners have to handle and, once you choose which version of the formula to use, density is easy to measure. It involves a simple calculation of straightforward urban quantities such as the number of people, of houses or of bedrooms, all divided by the geographic area over which those ingredients occur. Easy.
By contrast, intensity seems more difficult to pin down, not least because it appears to have a subjectively emotional dimension; it speaks of feelings, responses, stimuli; raising problems about how it can be measured. But intensity is also a response to context, to place and above all to people – and here we find clues to its measurement.
