Chapel within a church, constructed by Russian architectural consortium bornhouse in the San Stae church for the Venice Biennale. Luminous, simple design well-suited for a free standing structure as well. There is a video of the grid-based construction at the link.
I believe these are laser-cut wood panels...I'm interested in how this sort of delicate screening effect could be applied to the monolithic expanses of steel and glass seen so often in American church construction.
