About The Pitched Roof 주택
피치드 루프(The Pitched Roof)는 일본 가루이자와에 위치한 단층 주택으로, 매우 단순한 경사 지붕이 전체를 덮고 있다. 지붕 아래 공간 중 단 40퍼센트만이 실내로 둘러싸여 있어, 내부와 외부의 경계가 부드럽게 유지된다. 캔틸레버 구조의 지붕은 두께가 불과 200밀리미터인 구조체로 6미터 이상 뻗어 나간다. 접힌 L자형 면이 모노코크 요소로 작용하여 필요한 지지대의 수를 줄인다. 미닫이문을 통해 거주자는 생활 공간의 성격을 자유롭게 변화시킬 수 있다. 이 주택은 일본 전통 건축의 깊은 처마를 현대적으로 재해석한다.

- Unique Properties
- This is a house located in Karuizawa, Japan with an extremely simple pitched roof. Traditional Japanese houses do not create enclosed environments but instead, form spaces that enable easy transition from the inside to the outside. By forming a blurred boundary, only forty percent of the space under the roof is enclosed within the interior. While the inside is being used primarily by the inhabitants as living spaces, it is the outside that defines it.
- Dimensions & Packaging
- Floor: Single floor
Ceiling Height: 2,100 mm
Roof Height: 3.446 mm
Site Area: 1,059.18 m2

- Production Technology
- The cantilevered roof of over 6 meters, pushes the limit of the 200mm thick roof structure. By adopting a folded shape as the main structural element, it minimizes the support needed as compared to having a flat roof, which would require three times more of the support utilized. Like the Japanese papercraft, Origami, the L-shaped surface acts as a monocoque element – not resisting stiff but drooping about 5 centimeters under snow pressure like tree branches in the forest.
- Design Challenge
- In Traditional Japanese Houses, the space under the eaves is often associated with columns. However, these columns serve purely as structural elements to support the cantilevered edges and are not crucial in enclosing the space. Had technology been much more advanced, we would have been able to design without columns years ago. We are now able to achieve the real intricate quality of open spaces in Japanese Architecture - a feat that was not possible for carpenters 400 years ago.
- Research
- The pitched roof house is trying to reach a certain level of mutability by re-interpreting the traditional elements into modern context. In aiming to heighten qualities of architectural mutability, the work is tied into a long tradition of Japanese vernacular architecture known for its sliding doors, screens, and other boundary-modulating elements, such as deep eaves. These elements not only create the spatial fluidity, but also open the architecture to life-giving elements of sunlight, wind, and humidity, modestly scaled the ubiquitous digital lifestyle with a return of nature.
- Inspiration
- Deep eaves, as one of the most important Japanese traditional architecture elements in local monsoon climate, are almost extinct in modern houses. It is essential to comprehend the meaning of these traditional elements in the modern setting. With the latest technology, the house seek to reinterpret the deep eave in the context of a humid climate, retain and create more opportunities for these distinctive Japanese qualities to sprout forth in modern architecture.
- Project Duration
- The project started in July 2007 and finished in May 2009 in Karuizawa, Japan
- Operation Flow
- The house is designed for a well-known Japanese pop songwriter who wanted to create a place where he could disconnect from the pressures of daily life. The space enclosed enables the inhabitants to perform their basic living tasks while open space under the deep eaves allows them to connect to nature and the surroundings. The sliding doors which divide the inside from the outside can be used to realize the shift in ambiance within the living space.
