The Firma Casa project started to be developed in November 2008, when Sonia Diniz Bernardini, owner of Firma Casa, decided to renew her store, established in 1994. She invited the Studio Campana to make the project and they decided together to invite SuperLimão Studio, a young architecture and design studio, to make the project and develop a lot of ideas.The project consists in a two floor building with 500 square meters divided in a gallery, a retail store and, in the second floor, the offices. All of the steel structure, air conditioning ducts, and a grid of electric rails are showed in the ceiling. The beams can be used with industrial magnets to hang pieces, and pallets shelving can support different pieces with different dimensions. SuperLimão Studio looked to flexibility to develop the project with could be used for a lot of different exhibitions.A three pieces front door allows entering pieces of big dimension into the gallery and the whole concrete floor can support heavy weight objects, sculptures, etc. In the outdoor area the Elastopave® was used to give the floor the capacity to drain rainwater. To cover the whole façade, Fernando and Humberto Campana suggested a green wall with Espada-de-São-Jorge (Sansevieria Trifasciata), a plant with African origin and very diffused in Brazilian popular culture because of it’s protective superstition power. In front of this challenge SuperLimão Studio developed a bent aluminum vase, with an origami form to support the plants. There are 3500 vases with 9000 seedlings of Espada-de-São-Jorge.
