Oberrieden is located on the left bank of Lake Zurich, along a terraced slope that faces a deep perspective with the Alps in the background. The terrain is sloping, with the east side facing the lake and the south and west sides facing the other buildings. The different characteristics of the views, combined with the small size of the site, led to a punctual terraced volume. The structure is defined by a load-bearing shell in exposed concrete, inside the only structural elements are the staircase and the fireplace, which is located in the center of the building and represents the fulcrum around which the living takes place. The internal divisions are light and offer a free adaptability of spaces. The terraces and the openings are oriented in a differentiated way towards the landscape and to the path of the sun in the different phases of the day. The large terrace on the central floor, facing east, south and west, is an extension of the interior space and connects the different levels of outdoor spaces. The themes of living, topography, the different views and orientations, are synthesized in an essential solution, the space and the relationships with the outside are defined by the primary elements of the construction.
