The main timber truss for retail shop at the front room introduces the idea of “structure as furniture”, a free-standing individual component that is detached with the existing wall. The idea of moderate intervention with minimal attaches and less anchoring that will undermine the existing building is taking place in this project. The timber truss is a structure that supports the display shelf and integrates the wiring of lighting and air-conditioning units. Appearing as an inverted frame, the truss is a modest response of a new insertion to an old building.
