Han Bit Housing Development

Location: Herrliberg Architect: Burkhalter Sumi Architekten Photographs : Heinrich Helfenstein The volumes of the individual buildings are staggered, both horizontally and vertically. In this way they react to the sloping topography. At the same time slender end walls are made that help integrate the buildings entirely naturally in a spatial clasp between the development lower down along Schulhausstrasse and the retaining wall of the upper plateau. As a consequence the transparency of the former vineyard parallel to the slope is preserved. Next to the owner's house there is an "annexe" with library, workrooms and a large terrace. When one takes a look outside the red glazed larch lining to the reveals of the windows at the ends of the building work like a picture frame focussing the view on the Glarner Alps further up the lake or on ‹etliberg at the end of the lake. In contrast the 10-metre-long openings of the main facade are designed as panorama windows. The external concrete window surrounds screen the immediate surroundings, directing the gaze towards Lake Zurich and the range of hills behind it. Unplaned large horizontal planks were used as shuttering for the exposed concrete walls. The shuttering boards were placed by the building contractor according to two principles: firstly, that the joints were to be broken; and secondly, that the lengths of the boards were not precisely defined, that they all lie within an initially determined range. This strengthens the horizontal character of the shuttering and the handmade character of the concrete wall. The building envelope was constructed in a monolithic system using no expansion joints of any kind. The interior is clad like a sheath with insulation covered with white render. In contrast to the rather coarse, cool exposed concrete of the facade here warm white tones from Le Corbusier's Salubra series of colours are used. Together with the brushed oak floors this creates an atmosphere that evokes Korean interiors.
