The theme of the studio, spolia, is a term from archaeology, which is to place remnants in a new environment. The project started research of a historical river in the city—the Senne in Brussels. The river influenced the urban development of the whole city morphologically and typologically. Interventions regarding the river show how local people treat spolia. The site is also located along the trace of Senne. A typical wall was formed because of the covering the Senne. It indicates the history but also segregates and influences current situations. It serves as such an important role that it should not be easily discarded. It is the spolia for this site. There is a big difference between the two sides of the wall--living and working, nature and the built environment, leisure and production. The urban concept is to reuse the wall to activate the neighbourhood, increase housing and public facilities and remove the productive constructions to the suburban area. The urban regards the wall as the main spolia and returns the centre of the block to the public. The wall frames the public facilities and parks of the community garden. The architectural proposal continues the focus on the wall as the spolia and explores how to treat it on the architectural scale. The project deals with three issues: the urban gestures facing different sides, the combination of the elderly and the children and the reuse of the existing wall. Among these, to reuse and reconfigure the wall intertwine the other two and becomes the main spine of my project. In the architectural scale, the content of spolia can be enriched. The wall is not only a line. It has the thickness; it has structure; it has a function. The wall acts as the perimeter of the project and organizes programs. The two user groups share an event hall and the kitchen. They have visual connections but also have their privacy. The façade intends to remain the solidness of the wall and make the new open and light while ties in with the old. So for the new façade, the frame can open up the courtyard by reducing the mass of the wall. The original texture of the old is remained to highlight the old wall. The façade also uses similar bricks of the old wall but uses different bonding to create a subtle difference between new and old. Especially for the entrance, light and translucent material is applied to the cladding to express an opening of the old. The interior use wood floor and plaster wall to release the heaviness of the texture of the bricks. In conclusion, my project lies partly in the urban solution. It articulates and celebrates an existing wall from urban scale down to materialization. In different stages, the content of the wall is enriched and enhanced.
