Pavilion Siegen

The pavilion’s unique, planar form articulates an assured, yet subtle compression of space, framing views of the lake and the local topography; its tectonic rigour enables the floor plate and ceiling to cantilever some 6m beyond the lakeshore.

The scheme is both a weekend fishing retreat and a garage for three classic cars. A toilet and washroom facility is also included, as is a storage area for the client’s angling equipment. Detailing is measured throughout - from the integrated lighting to the fully glazed internal area.

The 12 x 12 m structure conforms to a strict proportional grid that determines both the position and heights of the walls, as well as the shuttering joints and fenestration divisions. The 3 x 3m door panels - built by the client’s engineering company, and weighing 340 kilos per door - pivot on bespoke spindles, enabling each to be opened with the push of a single finger.

Throughout the building process the concrete mix was carefully monitored so as to achieve a deliberate off white finish. This tone was felt to be essential in order to refine the pavilion’s dialogue with the surrounding terrain.

Structurally, the scheme’s main floor plate comprises precast concrete slabs, tied back to massive drum foundations; a finishing layer of in-situ concrete applied from above avoided the need for under floor shuttering and, just as importantly, ensured uniformity in the concrete’s appearance. The cantilevered platform formed the base for the in-situ cast walls and ceiling. Special, non-oiled shuttering ensured that no harm came to lake’s fish population during the pavilion’s construction.
