OAP was commissioned to develop a standard house, which corresponds to the current needs of modern living and to present-day concepts of planning, production, energy and building. The term standard house should not be confused with that of a prefabricated house. The approach is fundamentally different. Standard houses are based on a fundamental planning type, which can be modified and adapted according to the wishes of the client. They are either built conventionally by different trade companies, which the owner chooses together with the architect or the house is built through a general contractor. The challenge and at the same time great sophistication of this at first glance simple and clear concept, is to be able to offer the greatest possible flexibility within the preplanned basic concept. We continued to develop the very simple type, which consists largely of an inner support structure made of concrete with the necessary braced walls. The interior walls only function as space division. With standardized shell and building services, thus a great flexibility is guaranteed leaving room for individual configuration. For example, areas can be defined, in which individual installations can be customized and implemented to the wishes of the respective building owners. Thus planning of vertical plumbing and electrical lines in the area of the stairs does not require any changes. For the outer sheath various materials may be used, depending on the individual wishes of the building owner, adapted to the environment or local building codes.
This approach is not new. It was already partially propagated in 1914 by Le Corbusier with his system "Dom-ino". He himself was largely influenced by industrial buildings of its time and especially since 1878 by François Hennebique's applied ceiling-post system built in concrete.
We believe that this construction approach can not be out of date, but that it is suitable especially for the purpose previously described in the sense of: ¨System versus flexibility¨.
The concept for the standard house LUX 1 is based on one of a high, but pre-defined flexibility. This concerns both the planning phase as well as the time when the building is used. The vertical ducting for plumbing, floor heating and electrical installation enables the division of the rooms which can also be subsequently supplemented or changed as needed, without expensive re-installation of building services. Above ground the supporting structure consists of a simple reinforced concrete frame. The floor plate rests on the staircase walls and the reinforced concrete columns, which are integrated into the facade. The closed parts of the facade as well as the interior, room dividing walls are brick. The floor areas can be easily enlarged, depending on the slab thickness by up to 25%. The arrangement of kitchen, bathroom and toilet can be modified in a predefined and preplanned area. The standard house can be planned according to local planning guide lines, the orientation of the site and last but not least, to the wishes of the client in the previously outlined framework.
