Outside In House, by Takeshi Hosaka architects, - in Fijiyoshida, Yamanashi, Japan

This is a house for a couple and their three daughters. 
”I looked for how the residents here could live in harmony with such nature and climate even in a crowded residential area.
I planned a structure in which nature is horizontally and vertically incorporated as an integral part of the design of the structure to create a gradation from the outside area to the inside areas. To put it concretely, the open shed lies facing the south, which makes it possible for the residents to feel as if they were in one room, filled with a sense of unity with the wooden area.”

Love House, by Takeshi Hosaka, 2004-2005 - in Yokohama, Kanagawa, Japan

LOVE HOUSE is a house for a couple.
I draw the biggest curve on there with width and depth of a building, I distributed a place of a roof and a place of a sky with the curve、And I planned the stairs which went up from the first floor to the second floor with this curve. The main space of the building which these created, it is it with the space that it “is not indside, and is not the outside”. Quiet rain, intense rain, rain with wind … rain create various sounds. Light of the sun and moonlight play in the LOVE HOUSE, and rain and wind visit LOVE HOUSE, and birds and insects visit a tree and a fruit tree of LOVE HOUSE. We can know that all nature given on the earth is prepared in very small LOVE HOUSE. 

Acrylic House, by Takeshi Hosaka, - in Fujikawaguchiko Yamanashi JAPAN

This building is a residence for a young husband and wife and their three children.To be specific, we have made the extremely transparent, continuous boundaries between the inside and outside that don’t have joints or mullions by using heat-insulating, 20mm-thick acrylic boards. Acrylic fiber has very few impurities, so the surface doesn’t reflect much light even during the day, making it easy to see the inside from the outside quite transparently. We are hoping that we can achieve unprecedented transparency and a new connection between the inside and the outside that are not possible with glass constructions. 

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
