A hidden bath and disappearing walls await those who venture inside the Edinburgh property voted House of the Year by the Royal Institute of British Architects (RIBA).

Murphy House was announced as the winner on TV programme Grand Designs.

The five-level house by architect Richard Murphy is his personal residence and has been built on a sandstone terrace on Hart Street in Edinburgh's New Town.

It boasts a folding corner wall, sliding bookshelf ladders that glide around a secret library and a roof terrace.

Mr Murphy was so pleased with the building he wrote an essay about the process and thinking behind his "labour of love".

"It has been an enjoyable vehicle to develop a lifetime's themes and now it gives me great pleasure to both live there and to hear the remarks of the many visitors it has hosted over the last year or so," he wrote.

Planning consent was approved for the home in 2007 on the "awkward urban site", with construction completed in Easter 2015.

RIBA president Jane Duncan said: "The Murphy House is this year's best example of how to overcome challenging constraints - from planning restrictions and an awkward site in an urban location - to build a stunning house.

"Nearly a decade in the making, this house is a true labour of love for Richard.

"Part jigsaw puzzle, with its hidden and unexpected spaces, and part Wallace and Gromit with its moving pieces and disappearing walls, this is a model house of pure perfection and a worthy winner of the RIBA House of the Year 2016."

Owner Mr Murphy said: "We celebrated our 25th birthday last month and to receive this award is a wonderful present and with such astonishing level of public interest.

"It's our 21st RIBA award and takes its place in a long line of awards for buildings small and large, and for whole variety of types including domestic, educational, health, arts and a new British Embassy.

"It emphasises yet again that the practice demonstrates both great versatility and consistently high quality in all its work current and past."
