Mixed House 混合宅
The project is located in an ordinary village on the outskirts of Beijing. As approaching this project, the design team intended to present an architectural status that mixes the old and new, and to build a connection between the project and the built landscape of the village. The goal was to let the renovated architecture integrate into the village with a low-profile gesture, and meanwhile to create a rich and natural small world inside the courtyard house.
The new addition is an undulating wooden construction, which replaces the old rooms at the middle of the site and extends to north and south sides to create spaces for daily life use, hence shaping a new pattern for the courtyard compound. The new wooden volume undulates in line with the old roofs, and forms two continuous roof ridges, under which are major public living spaces including living room, dining room and kitchen. The insertion of the new wooden construction strengthens the undulating layering of the roofs, and creates a dialogue between the old and new building volumes.
The newly built wooden construction adopts cedar plywood as main material and applies traditional beam-lifted frames, to echo the features of traditional northern Chinese houses. By fully utilizing plywood, a low-carbon and renewable natural building material, the newly inserted wooden construction continues the existing old house's wooden frame with new structural expressions, hence creating a dialogue between the old and the new. Moreover, the undulating new roof is constructed with beams and columns featuring minimized cross sections and maximized spans, to ensure a reasonable structure and control costs.
