Kevin McCloud visits a couple who are looking to build their hi-tech modern house in a quiet north London street. Sarah Jordan and Coneyl Jay have long dreamt of the perfect work and living space. Unable to find what they were looking for they decided to build their own. However the site they have found is situated in a predominantly Edwardian street. While they wait to see if the council approve their plans, they employ architect Mike Tonkin to realise their vision but can their ambitious project ever become reality?
