*화산재 콘크리트로 지은 도쿄의 마이크로 하우스-[ Atelier TEKUTO ] Concrete Micro_House in Japan Works All the Angles

화산재를 이용해 만든 특수 제형 콘크리트로 지어진 도쿄의 마이크로 하우스는 수직구조를 통해 공간의 극대화를 꾀한다. 독특하고 환경친화적 콘크리트 주택을 건축하기 위해, 약 2년 반동안의 재료 탐사가 진행되었다. 결과, 2017 년 American Concrete Institute Awards에서 저층 건물 부문에서 최우수상을 수상했다.
Atelier TEKUTO는 작은 장소의 작은 집들이 천장 높이와 같은 횡단면, 수직 요소, 바닥 사이의 연결이 제한되어 있기 때문에 안락한 실내 공간을 만들기 위해서는 공간을 배치하는 것이 필수적이라고 설명하면서, 유사한 색과 질감을 사용하면 공간이 실제보다 크게 보일 수도 있다고 덧붙여 설명했다. 친환경 건축 자재에 대한 고객의 요구를 충족시키기 위해 Atelier TEKUTO는 모래 기반 콘크리트의 대안으로 재활용 가능한 콘크리트의 공식을 개발했다.


 

Built with specially-formulated concrete made of volcanic ash, this micro-house in Tokyo maximizes space through vertical construction.

When Tokyo-based architecture firm Atelier TEKUTO received a brief from their clients to build a distinctive, environmentally-conscious concrete home, they embarked on a two-and-a-half year journey of spacial and material exploration. Built in 2015, the result—the R Torso C project—recently won the Overall Excellence Award and first place in the low-rise buildings category at the 2017 American Concrete Institute Awards.

Working on a small, corner plot of roughly 718 square feet in a densely populated neighborhood of Tokyo, Atelier TEKUTO increased the home’s floor plan by building skywards. A living room, dining room, kitchen, and bathroom make up the top floor, while the first floor features a spacious gallery and a traditional "Japanese room," which has a tatami mat floor. The basement houses an insulated audio visual room. 


According to the firm, sectional and volumetric design is a cornerstone of building micro-houses such as the R Torso C project. "Since small houses on small sites have limited floor area, cross-sectional, vertical elements such as ceiling heights, the connection between floors, the placement of voids are essential to create comfortable interior space," says Yasuhiro Yamashita of Atelier TEKUTO.



The studio, which is known for its micro-houses, also relies on strategic placement of windows and skylights to maximize the perception of space. Yamashita adds that the use of similar colors and textures also makes the space seem larger than it actually is.

To meet their clients' request for eco-friendly building materials, Atelier TEKUTO developed a formula for recyclable concrete as an alternative to sand-based concrete. The key ingredient in the concrete is shirasu, an extremely fine volcanic ash that comes from the south of Japan. Shirasu offers more durability and density that traditional concrete, and its smooth texture creates an ideal finish for exposed concrete surfaces. The new concrete is still under development, but has potential applications for environmentally-friendly architecture.
