The site is located in the village of Pičín (near Jankov) on the shore of the Pičín Pond. The plot is flat, gently sloping toward the northeast, and forms part of a continuous development of detached recreational and family houses, typically one to two storeys high and roofed with pitched gable roofs. The existing building, originally a long, barn-like structure with a gable roof, is being extended. The architectural concept is based on a clear distinction between the original structure—kept in traditional materials and maintaining its existing proportions—and the new extension, which is designed in a contemporary manner. The massing of the extension draws on the archetype of a barn while incorporating modern detailing. The extension is designed without roof overhangs, featuring a timber slatted façade and metal roofing. The gable end of the extension facing the pond is fully glazed up to the roof ridge. The building’s structural system is steel, eliminating the need for interior collar ties or tension rods. As a result, the external envelope can be expressed cleanly and consistently within the interior.
