Semi Detached is a minimalist residence located in London, England, designed by Delvendahl Martin Architects. The project involved the conversion of two semi-detached houses in central Oxford into one family home. Two existing Victorian houses are joined together by introducing a new staircase at the centre of the plan and perpendicular to the party wall. The existing symmetrical arrangement gets thus rotated to achieve a continuous flow of spaces throughout each floor. The change of level from the entrance to the back garden is negotiated by introducing a second staircase and a new loggia accessible from the kitchen and main living room of the house.
