M Pavilion is a coffee shop commissioned by M Stand, located in the lobby of an office building in Shanghai. In order not to disturb the daily operations of the building, we applied two basic strategies in the design: rapid construction and a light touch to the site. We came up with an adaptive system with only one prototype of component and very few variations that restrict the construction process within 10 days. This system covers all aspects including structure, envelope, bar worktops, lighting, foundation floor, making it possible to bring beauty out of a rapid construction.
