Daylight House, by Takeshi Hosaka, - in Yokohama, Japan
Natural light diffuses into this house through a grid of arched skylights in the ceiling. The translucent acrylic panels cover the entire ceiling of the single-storey house.
Windowless timber walls line the interior, where four bedrooms and a study surround an open-plan living room. A table at the centre of this living room has a glass surface that reflects the ceiling lattice overhead.
Ladders lead up from two of the bedrooms to a mezzanine loft, which can also be accessed via an adjacent staircase.
Daylight House was awarded second prize in the AR House 2011 awards
