Disappearing walls and hidden bath wins Riba House of the Year

A property in Edinburgh with a hidden bath and disappearing walls has been named house of the year by the Royal Institute of British Architects (RIBA).

The five-storey building fills an end-of-terrace plot in the city's New Town.

RIBA described Murphy House as "part Wallace and Gromit", with its moving pieces and surprises.

Richard Murphy, the architect who designed it, said he was delighted to have won.
