The Skate Park house was custom built for a Shibuya, Tokyo couple, integrating a skate-ramp, a piano studio, and many lovely design flourishes. I think the stair-rail looks like it'd be awesome for grinding, too -- or at least soaping.
The owners of this house, a young married couple, made a special request in regards to the design of their house, located in a quiet residential neighborhood in Shibuya ward. They wanted both a skateboard park and a piano rehearsal room to reflect their own individual interests.
There was no need for a car park on the site, so to take advantage of space a private entrance courtyard was designed. The sliding glass panels of the first floor open up onto this enclosed area and allows for the workshop and studio to expand outwards. The studio has a skateboard bowl imbedded into the floor with multiple angles for plenty of different interaction.
The piano room, located at the back of the studio, is raised about 2 feet from the ground to help with the sound-proofing of the room as well as creating an inherent stage performance space. When the doors open up onto the studio, the expanded space with the bowl transform into guest seating and completely changes the atmosphere from a mere practice room to a public concert hall.
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
