This great project, called Tea House was designed by by Archi-Union Architects, a  studio from Shanghai. Concrete walls twist up through the interior of this tea house and library that Shanghai architects Archi-Union have constructed in the backyard of their studio. The building is constructed from the salvaged parts of the original warehouse’s collapsed roof. The site was extremely constricted with walls on three sides, and with only one side facing towards a nopen space that contains a pool. Constructed from timber-formed concrete, the two-storey building has a glass facade. The space was further restricted by a mature tree.The design tries to embody harmony by integrating enclosure and openness, delightful space and logical construction and other complicated relations. A delightful transitional space was created to connect the public space and the private spaces.
