This dining hall for disabled children care center is a charity project. The design needs to accommodate the function with avery limited budget. The building is conceived as a very basic device responding to most essential elements of nature: rain, wind, sunlight and view. In the main space, a 7.2M long dining table is the daily place for children to eat and play. The fixed glass at opening for view and wood window for air is to gain an essential meaning for each element. The changed angle of roof is for better rain draining effect. The economical construction method and material is applied including brick load bearing wall, steel roof truss, corrugated metal roof. Although built in a very low cost, the building is a fundamental return to the essence of architecture, being silent and poetic.
