大屋根に穿たれた穴は、まるでウサギ達の棲みかのようです。全ての住戸は空に向かって配置され、冷たい北風が冬の訪れを告げると、1つ1つの住戸には雪のプレゼントが届けられます。広場にも、真っ白な雪がガラスのショーケースの中に舞い降りてきて、冬の到来をセンセーショナルに告げることでしょう。うさぎ小屋と揶揄される日本の小さな住空間が、ここ青森、雪国にて魅力ある「rabbit housing」として生まれ変わります。構造的には、集合住宅特有の間仕切り壁を利用した梁高6300mmのプレストレスコンクリートによるフィーレンデールハニカム構造により無柱の「かまくら」のような大空間を形成しています。また基礎梁も設備及び駐車スペースとして利用され、積極的なspace in  structureが試みられ、お互いの空間の成立を相互に定義しています。

The holes drilled in the huge roof resembles a rabbit cage. All houses reach out towardsthe sky,and when the Northern wind starts to blow, softly and softly down comes the snow,as if present from the sky.At the platform too, snowflakes dance in the glass, indicating that winter has come at last. Tiny little Japanese housings known as "rabbit cages" is about to be reborn as "Rabbit housing" here in winter-land, Aomori.

The accumulated snow on the roof will reinforce the heat-insulation. The beautiful snowflakes will fall

through the holes into the houses to indicated winter's arrival. The snow falling down into platform

will turn into a picturesque tower of light, and , the snow gathered from the surrounding streets will

be reserved in the snow pool as resource to support the summer air conditioning.

"Rabbit Housing" is an urban housing for snowy regions that attempts to blend living and commercial space by harnessing snow as a medium. 

Both big and small holes are made in the roof so that rays of sun will pour into the platform and streams of light will sprinkle into each and every house unit. Rabbit will be running around the maintenance-free roof top garden.

Each resident will enjoy their own sky, the heavenly milky way of the winter, the towering thunder clouds of the summer, the sun, the rain, the twinkling stars and the moon, and yes, the falling snow.The houses facing to the sky have relativity to the issue of orientation (facing South) that contemporary Japanese apartments have continuously faced in order to capture mother nature and bring the outdoor world, that is the weather movement and seasonal changes, into people's daily lives. For a snowy country that has a lot of cloudy days, this brings forth a new horizon to theconcepts of living as well.

Despite the size being 80・, the "Rabbit House" will enable people to seize the movement of the sun, and the flowing of time as if in the Pantheon. The small garden of which is 3 meters across will bring residents much joy and happiness as it becomes decorated with flowers and Christmas trees, or becomes a place for barbecues, SUMO wrestling…etc.

With each housing unit coming together to form an "igloo-like" shape, a new all-weather open area is born in the town.There will be three kinds of infrastructure running similar to the lines of gymnasium, and each facility will be able to arrange their spaces freely by choice. This offers people a new type of a commercial or cultural space that creates an unrestricted, free and relaxed environment such as a free market or a pedestrian's paradise. In addition, each of the 4 holes of which are 18m in diameters, will carry down rays of light from the sky, and in winter time the glass tubes will turn into showcases that exhibit the snowfall of winter wonderland.

The Vierendeel honeycomb structure of 6300mm tall pre-stress concrete of which incorporates the wall peculiar to housings, has been transformed to this "igloo-like" spacious saloon with nocolumns. Furthermore, there is an active engaging in the "space in Structure" that attempts built each space so it will define the other. This can be seen where the space for the footing beams isutilized as parking and infrastructure space.
