brass house

Two spaces under the two roofs


The site is known as the birthplace of Somei-Yoshino cherry tree, and is located in a dense residential neighborhood in Somei Komagome, Tokyo. While yearning for the open spaces, the owner wanted a house providing privacy from neighbors. Combining such contradictory directions would be a big challenge


The house is flanked by houses and buildings on both sides but, fortunately, two open spaces in front of and behind the property allow the creation of a vista in this crowded place, and which made us think that whether it was possible to incorporate this house into such built-up area? Half of the house is shown from the open space and the other half is stacked by closed spaces. Considering the symmetry, the southern elevation was designed in the shape of a iegata, with two roofs hanging over a center ridge. Wasn’t it possible to juxtapose the spaces with different qualities under the two roofs and to combine them as one house?

Designed to reflect sunlight, walls and ceilings are silver painted below one roof and at night, some brass elements will reflect into the silver space. The street side was greatly externalized, and the roof made of CLT floats lightly above the 1st floor terrace. Leaving the open view as it is, a series of spaces free of purpose were made.

Under the other roof there is a daily space with a 4.7m high ceiling. The hall is surrounded by huge walls, that were finished with white sponge paint to make them look like fluffy clouds. Wrapped by soft light, the ceiling has become a deep cave. The private room over the hall is a nest-like space, and by using slope ceiling, the necessary minimum height was secured. These two closed spaces are connected to the open silver world via a large opening.

Instead of calling one space as daily and the other as non-daily, these two spaces are always complementing each other. By intersecting comparison and inducing a complimentary relationship we attempted to leave poetic nuggets throughout the house to shine on the owner’s daily life.
