 In each episode, presenter Simon Davis visits the owners of a private house, then stays overnight so he can comment on what the building is like to actually live in.The preceding series visited older "classic" buildings (1930s to 1970s) where modernity was the key feature.In this series, buildings have been constructed in the last few years and often rely on cutting-edge materials (the glass walls at "Skywood") and have "green" elements of re-use ("Quay House" is a rebuilt dairy) and efficiency ("Drop House" glazing and walls).
