River Side House in Horinouchi by Mizuishi Architect Atelier
Mizuishi Architect Atelier have designed the River Side House in Horinouchi.

.
Description from the architect:
This is a very small house built on the triangle site which the river and the way were crossed and made to the acute angle.For the dead-end road, it became a plan in various regulations for obtaining special permission. Residents are husband and wife and a little girl. Although it was a novel site of a limited area, since a river was faced through a bank and a promenade, I would like to build various relations with the river. The building is the form that cut an acute angle part on a triangle plan derived from the site.Furthermore,it got the maximum volume of hip roof of three planes in restriction of setback-line. Although the level0 floor was a private space,it limits for dividing with the curtain of a race in the door, stairs, storage, etc. except for a bathroom. It enabled it to feel a spread. The level+1 floor is devided into small areas by structural narrow walls,being connected with one by the ridgeline of a roof.So there are different open feelings and the relations with the river each.
1. Dining&kitchen/The west side space up the stairs is the largest planarly, and has high ceiling with a feeling of rise towards the roof top.
2. Living/The central space is low ceilinged,and has full-opening windows on both sides as a balcony and the bay window that spreads outward with a feeling of floating
3. Spare room/The east side space in the deepest is a form which is narrowed down to the direction of flow of the river,and is a space watching the light to insert earlier of the abyss.
4. Loft/The space with two skylights is a space looking down at the river and looking up at the sky.

This is an AMAZING house. Its meek on the outside and surprisingly big on the inside. Clean, elegant, and simple offering with enough space for a family of three with some good size openings! A+ in my book.

I simply love. I think it is ingeneous without over stretching it’s self. What a delightful and efficient use of space!

So much natural light! That is integral and well-executed. Reminds me of Patricio Cuello’s 12-inch house.

My guess is that those boxes under the living room bench contain traditional tatami or modern cushions. No need for Western furniture to be comfortable.

Goza and Tatami on 18 Oct 2011 at 7:58 pm #
Amazing house considering the shape and the size of the land, even the surrounding environment is not attractive at all.
Angela: Tatami is a solid heavy fixture with a prox. 5.5cm core made of rice straw and cannot be folded.On the other hand, Goza is a mat (rug) made of woven soft rush straw and can be folded in just one direction along with the straw.
Tatami requires daily and periodic maintenance and it is not a easy matter, especially if you have child.
Well maintained Tatami with quality is a extremely comfortable fixture, but it is not a exotic material for Japaneses at all.
So in Japan, for a mid class family in a bed town, western style interior fixtures (even in many cases somewhat obsolete) are preferred than traditional one.
