A Music house is designed in the context of the Norwegian city, Stavanger. It relates to a site with dramatic height changes, overlooking the fjord and the distant mountains covering the horizon. The cultural area of Stavanger East has a vivid music and art environment, which, however, lacks a scene for non-amplified music - a place for people to learn, teach, perform and enjoy every aspect of music. Architects from the Nordic countries and Japan have in the past and present been influenced by elements in one another’s architecture. This project studies the fusion of the Nordic and Japanese traditions by creating a Music House. Nordic elements such as human scale, the appreciation of light and a relationship to the context, establish the foundations of the design together with the Japanese feeling of tranquility and harmony - to seek boundarylessness. In the frame of the Nordic and Japanese tradition, music evolves by being shared, taught and played. This calls for a venue where activities can be of a two-way communicative form. Forms and materials have been chosen with careful consideration of both aesthetics and acoustic expression. Rehearsal rooms and a performance hall have integrated acoustics in the design process. CATT Acoustic, a 3D acoustic modelling program is used to help determine an acoustic form and materiality. The outcome results in an integrated expression of Nordic, Japanese and Acoustic architecture - thus a Nordic Japanese Harmony.
