■MAIN CONCEPT
Built in the residential area of Tokyo, Transustainable House aims to respond to 4 features of urban housing.
1) ‘Small building site’ – Extension of perceptional spaces beyond limit
2) ‘Artificial thermal environment’ – Diverse thermal environment that offer choices
3) ‘Diverse style of living’ – Composition of spaces that allow arrangements
4) ‘Endlessly updating townscape’ – Surface that engraves the microclimate
These procedures make interior and exterior durable to different contexts. The interior responds to transitions of residents’ lifestyles, while the exterior responds to transitions surrounding the site. This house is not brought to perfection in moment of completion, but targets to enrich the quality of environment by being intimate with the long lapse of time. Connecting people, time and objects, it is the ideal form of architecture.
■DIAGRAM 01: Extension of perceptional spaces beyond the limit
To maximize the limited dwelling space, this house converts the entire site into a composition of spaces. Private rooms placed diagonally create ‘semi-indoor’ areas, connecting and extending spatial perception beyond the site boundary.
■DIAGRAM 02: Diverse thermal environment that offers choices
This house offers 4 approaches to air conditioning and create countless thermal condition in between, stimulating residents to search for the adequate places every time perceptively.
■DIAGRAM 03: Composition of spaces that allow arrangements
Composition of rooms and places respond to the nomadic style of urban life, by allowing free arrangement. If all 50,000 houses in Japan adopt this method and open partially to nomadic citizens and community, they can play a major role in society as a stock of enclosed dwelling spaces.
■DIAGRAM 04: Surface that engraves micro-climate
This house relies on the site-specific micro-climate, rather than the scrap-and-build townscape. This aim is realized by exterior surfaces with iron-powder-mixed-plaster and expanded metal that weathers over time.
