The Density of Housing in London

The UK government has set a target of building a million new homes by 2020. This raises the question of where do you put a million new homes. In the past the government has wanted to relax laws which restrict new buildings on green field sites. However building on green field sites is usually very unpopular with voters. An alternative approach would be to build more densely in already built-up areas.

EMU Analytics and London YIMBY has teamed up to show that there may be many opportunities to build new homes in London. The London Housing Density map shows the number of homes in each Lower Layer Super Output Area (LSOA) in London. The map uses a 200x200m grid and clips around known non-residential areas (such as large parks) to give a reasonably accurate picture of the housing density in each LSOA.

The London Housing Density map also includes layers which show residential and non-residential building heights. These additional layers show where there might be more scope for increasing the number of homes by building taller apartment buildings.
