Recently completed, Ott’s Yard is a residential development for two new triangular houses with green roofs designed by Arabella Lennox-Boyd. It has won an RIBA London Regional Award and two awards at the Ideal Homes Show's Blue Ribbon Awards: Ideal Home of the Year and Housing Architect of the Year. The site is located at the centre of a residential block in North London, surrounded by 23 party walls and accessed via a long narrow passageway. The plans are based on an abstraction of the existing triangular geometry: two houses, each with their own garden, and a shared communal courtyard emerged out of a pinwheel fractal pattern. The sloping roofs of the houses will be planted according to the same geometry, to be designed together with landscape architect Arabella Lennox-Boyd.
