Coussoir Cloud – case study

Case study

Voussoir Cloud, IwamotoScott Architecture

Design : IwamotoScott Architecture, Lisa Iwamoto/Craig Scott

Voussoir Cloud explores the structural paradigm of pure compression coupled with an untra-light material system. The design fills the gallery with a system of vaults to be expeienced both from within and from above. The edges of the vaults are delimited by the entry soffit and the two long gallery walls.

Buro Happold used both computational hanging chain models to refine and adjust the profile lines, initially modeled in Rhino, and form finding programs to determine the purely compressive vault shapes.

The structural and material strategies are intentionally confused. Each vault is comprised of a Delaunay tessellation that both capitalizes on and confounds the structural logics – greater cell density of smaller more connective modules or petals, gang together porosity. And the petals – the reconstituted ‘voussoirs’, typically defined as the wedge shaped masonry blocks that make up an arch – are reconsdered here using paper thin material.

The three dimensional petals are formed by folding thin wood laminate along curved seams. The curve produces an inflected and dished form that relies on the internal surface tension of the wood and folded geometry of the flanges to hold its shape.
