A development of four new-build houses on a back-land site in Ealing, West London. Two pairs of semi-detached houses sit around a shared green space with facades set back behind sunken courtyards and elegant railings, in a contemporary play on the arrangement of a classic London square. The gable-ended form unifies the homes with continuous hung-tile defining roofs and flank walls. Layered entrance porches mediate privacy. Each house provides one storey of living accommodation at ground level with a private side garden while bedrooms and bathrooms are below ground, served by a sunken courtyard terrace.
