The 2500 sf Dub residence, located in Germany, was conceived as the intersection of two basic volumes; a low stone volume flanking the street with a wooden T-volume crossing over and cantilevering out over the garden.PREFAB- Using prefabricated construction techniques, the Residence was constructed in 3 days and fully finished in 6 weeks. This short and predictable process eliminates the usual stress a client has related to unforeseen costs and unpredictable construction time. On the other hand it adds a high quality and precision to the construction and the engineering. The 15’ cantilever was essentially built as a wooden composite beam without the addition of any steel.The stone ground floor volume contains living, dining, kitchen and master bed-, and bathrooms. Perched above the stone volume is the cantilevered second floor with a double-height atrium to the office, where one also finds storage rooms and the guestbed-, and bathrooms. This lightweight box of wood and glass is angled towards the garden and ends with a generous balcony. Its cantilever creates a shadowed terrace below directly off of the master bedroom. ENERGY EFFICIENCY/LOW MAINTENANCE - The prefab panels provide a very high insulation level, which reduces energy consumption. The use of glass at strategicplaces allows for passive solar energy. The radiant floor system guarantees an efficient heating and cooling system. The choice of natural materials for the exterior promotes a natural ‘aging’ process and a very low maintenance level: untreated reclaimed Ipe siding for natural resistance to decay & weathering; reclaimed wood window & door framing with 1’ insulated glass units.Prefabrication helped us to make the Dub Residence an affordable intelligent building with 6 weeks construction time.
