Selected Competitions



We seek architectural vision which originates from the particular features found in every design task and its environment. Thus we attempt to create places that are meaningful, which we believe to be the mission of architecture. We examine the varied scope of building through trial and error trying to find a solution that fulfills the needs and creates the final form that reaches the emotional level.

Our office has experience on a broad range of design tasks. Design commissions range from urban planning to small scale detailing. The emphasis in our work has been on designing public buildings.
