Structural engineer: Thomas Beck, A.K.A. Munich-based   Peter Haimerl Architektur   designed the 500-square-metre venue for the small village of Bailbach, in the Bavarian woods. The heavily textured stone cladding of the exterior contrasts with the smooth concrete and timber walls that line the interior spaces and auditorium. «The dominant tilted surfaces of the concert hall are based on acoustic specifications,» said the architect. This   faceted timber-lined corridor includes   cloakrooms, toilets and a bar. Ingenieure

These «lively» textured surfaces are designed to help dampen sound, with bass absorbers located beneath the slits and under the steps to achieve optimal acoustics for the space. In the auditorium, slivers of artificial light stream through gaps between layers of untreated concrete that make up the walls. Photography is by Edward Beierle.

A flight of concrete steps leads visitors through a hole in the ground into a cavity beneath the granite hood, where an underground lobby wraps around the rectilinear auditorium. «The monolithic tilted building opens itself to the visitors at the new village square and guides them by a staircase to the foyer below the surface,» said the architect.
