endo architect and associates has developed the design concept of ‘tsunagu house’ with the aim of creating a total integration between architecture and engineering system. ‘as the word “integration” suggests “action of linking”, we have named the house “tsunagu (link) house”’, explains the japanese studio. a simple yet strong concrete building frame and exposed services characterize the two-story building, implementing the possibility to equip residents for future changes.reflective curtains divide tokyo home's raw concrete interior by endo architect and associates

 

 

the building is composed of reinforced concrete frame construction with 250mm square columns and earthquake resistant panels. the exterior features 75mm thick thermal insulation panels on the wall and 100mm on the roof, which are then wrapped with galvanised steel sheets with air space in-between. window and door frames are not fixed directly into the concrete structure to maximise thermal insulation. a hydronic underfloor heating system is installed, which stores heat in the concrete slabs and the heated internal air is then stored in the walls and roof.

 

‘this creates an adequate thermal comfort in indoor environment throughout the year,’ explains endo architect and associates. additionally, the tank stores 5T water at all time. during a natural disaster, this water can be supplied to neighbours in need, thus contributing to society.’reflective curtains divide tokyo home's raw concrete interior by endo architect and associatesreflective curtains divide tokyo home's raw concrete interior by endo architect and associates
