Answer

We can’t fix the housing crisis without building more homes, and the spatial plan will help get those homes built close to where people work, study, and socialise. But intensification alone won’t fix the housing crisis. 

The Spatial Plan (and lots of other changes) will ease some of the current barriers – low height limits and blanket bans on demolition – that are preventing more homes being created in places that are near to things we need to do in our lives, which are natural 15-minute neighbourhoods

The housing crisis also has lots of other dimensions besides not enough homes being created in cities, and the Spatial Plan doesn’t touch these dimensions. A good summary is in Generation Rent.
