A white structure with striking silhouette is about as eye-catching as the signs at the adjacent highway truck stop, yet its form clearly indicates that it is a place of worship: the easily recognisable church pictogram has been transformed into three dimensions. In contrast to the abstract, folded-paper aesthetics of the exterior, the interior surprises visitors with it sculptural organic forms. The space inscribed by the inner skin tapers toward the entrance and opens up at the altar. This free-standing, self-supporting construction is made of 30 mm thick oriented-strand boards that are connected by means of insertion in slots. The zone between the organic inner shell and the outer shell contains the vestry, as well as space for storage. The inner shell’s geometry originated in the 14 ? 14 metre church space: it is based on a semi-hemisphere, and its interpolation with the outer shell was developed in a parametric design process. Then a grid was employed to determine the position of the ribs and the amount of material required. The individual elements were pressure-adhered with dowels on site, then the slotted sheets were assembled. At points along its base, steel angles secure it.
