DERUFA decorating coatings showroom project is a reconstruction of a small, attached commercial space. Despite the small scale of the building, we have tried to turn it into an interesting and unusual architectural object. We have been treating it as a design object, cutting off all the unnecessary details in search of harmonious lines. The architecture and the interior are united and share the same philosophy. The interior idea is based on the principle of mobility: the showroom's exposition can be modelled at option. This shaped the structure of the whole interior and, consequently, exterior space. While fulfilling the client's needs we managed to avoid utilitarian and random aspects. For us this became a small riddle, demanding thorough architectural insight.
