You have to visit Abode to see the long list of small steps it takes that are giant strides in housebuilding, from the bonded-gravel shared surfaces to the landscaped trees that take precedence over cars. Congratulations to masterplanner Roger Evans, local authority Harlow, the landowning Moen family, and Countryside Properties.
David Adjaye's trick is to find ways of illuminating darkened cells. They can be as evocative as winter sunshine, but the idea of a house that is just a blind box with a windowless plastic frontage and light diffused from rooflights is, to urban planning, condom architecture. However exciting the initial thrill, it will dull the pleasure for those inside.
