InBetween House in Karuizawa, Japan by Koji Tsutsui Architect & Associates

 
May 10th, 2011 by Sumit Singhal

Project update: November 4, 2011 — It wins ‘World Villa Of The Year’ at the 2011 World Architecture Festival

The client chose the sloped site surrounded by Japanese larch trees and located in a mountainous region, an hour away from Tokyo on a bullet train, as their ideal location for their home where they can retreat from their busy work in the city.  The house sits on an artificially leveled area of the site created thirty years ago and left unused.  Since the client wanted a house seamlessly blend into the natural surrounding, topography and local culture, we designed this house as a collection of small mountain cottages.

Interior View

It consists of five single pitched roof cottages that are clad in the local larch wood siding.  Rather than using a complex construction technology, it is built in a traditional Japanese wood construction method so that local builders can skillfully craft each structural wood member.  Each cottage varies in size to fit its function and set on site at 30 degree increments to best fit the topography and to face unique views.  All cottage roofs have varying slopes and overhangs that touch the overhangs of adjacent cottages, creating gap spaces between these cottages, a simulacrum of alleys in a city.  The triangular “connecting” roofs span between these overhangs to capture these gap spaces as a single fluid public interior space, which serves as a living room or a circulation space and feels like being outside looking at mountains in the distance.  Since these connecting roofs bend & fold to connect the cottages at multiple angles & heights, the in-between space result in a spatial & structural warpage.

Interior View

The design intent of this house is not the final architectural form, but rather, establishing a set of design rules of cottage placements and connections, which allows the house to be freely arranged to satisfy any requirements and adoptable to any future changes or additions, prolonging its building life.
