Curved Aluminum Alloy Roof

Location: Imperial Palace, 1 Chiyoda, Chiyoda, Tokyo
2005 15th AACA Award

Ga Japan vol.75
Shinkenchiku vol.80, no.13

 

Concept:
The roof, which looks like airy-fairy, appears more a wing than an alloy. It expresses the warmth and comfortable mood. Because it is surrounded by trees, it blends right in with the quiet area.

Style:
For creating welded construction we took advantage of characteristics of specific strength of aluminum alloy. Indoor ceiling, which is made of aluminum alloy, reflects lights and green of the surrounding trees.


Features:
We created a three-dimensional curve using plate forming technique for shipbuilding with just fire and water. In order to joint concrete and aluminum alloy by welding, we used aluminum alloy clad steel.
