Aizawa Concrete — Namie: a church-like hall of precast concrete

Concept

A hall facing the sea

Churches are built facing east. The building stretches from a large opening on the west side of the test hall towards the sea in the east, in the hope that technology born here will help the recovery.

The prestressed precast method makes the building strong against shaking and also flexible like rubber.

01 · Making

All on site

All 318 precast pieces were made and assembled on site, and the design, production and construction were all handled by ADAAC. Places with different ceiling heights cross each other like a converted building.

02 · 3D printing

A curtain blown by the wind

A concrete 3D printer is part of the design. Wind blowing across the site was simulated in Houdini, and the result was printed as a curtain wall that looks like a curtain moving in the breeze. Printed parts were also prestressed into structural walls.
