“On the cherry blossoms” House in Tokyo by Junichi Sampei/A.L.X.

March 7th, 2011 by Sanjay Gangal

This house faces the park where two splendid cherry blossoms trees exist facing front of a road on the north side. As for a peripheral environment, there is a parking lot facing the private road on the east side; there is a parking lot in the apartment house on the west side; and the timbered house of two stories built in the south. In a word, it is a place opened to the three directions.

This place gets little sunshine because of the north direction. It has conflicting elements. This location is dark but openhearted and enclosed by an apartment house and a narrow house though the view is good. The park in front of the site was not a park where the environment was good and there was a graveyard, too, so the view of the outside was not good.

The most impressive thing is that the comfort of ground level isn’t so good, but you could expect it to become better dramatically beyond a certain height. Of course, two cherry trees play a important role in that.

Then, it was proposed that the manner of living should focus on the relation to cherry blossoms. The main living spaces of the living room, kitchen, and utility, etc. were concentrated on the third floor, and the maximum architectural area was secured.

It was thought that shortening the distance feeling of a grand level and the third floor in the sense was necessary to pass this composition. Therefore, the entrance was set up in the mezzanine on the external stairs, each room tied in the spiral staircase, and arranged three-dimensionally.

It became a composition to which the floor space decreased near ground since the third floor was placed at the center of the life scene.

The volume of the third floor secures the view and the lighting with a tunnel space that runs through the south north. However, it was thought that it wanted to do to a place near an external space like the roof garden l rather than the room.

Moreover, the third floor moved cherry blossoms in the stared direction to bring the relation between cherry blossoms and the house as close as possible. The gap generated by this contributes to the lighting in the under floor from ceiling light.

Windows and doors of the first floor and the second floor are small, and the reason is that the shut space guarding the privacy of one’s home such as bedrooms.

It is also a big reason that comfort in outside space to the level of the 3rd floor wasn’t judged good.

Scenery and light are partially taken in small windows, a slit, a high side light, a top light, and small window for ventilation that integrates with the outside wall until reaching the third floor where the cherry blossoms tree is seen.

The composition that should be called a reverse-set back who attenuates this shape from the upper part looks like the tree of two cherry blossoms that expand the leaf as a result for light and grow up to length.

The shape that floats on air for the light, the comfort, and cherry blossoms shows house’s existence like another tree.
