Arkides studio/Sarimanah Office is a renovation project converting a house to a design studio. Layout of the office space is made to be like the layout of a house, with the aim of giving a homey impression. This concept is based on the fact that designers spend a lot of time in the office as a result of design workload so that this office can be a second home for them. The design tries to present itself with 3 basic geometry; gable-shaped mass, cube-shaped mass, and rectangular plane; that is composed by making the rectangular plane as a basic foundation for the two masses. The masses are then separated by a transparent finishing as an effort to give a monumental impression to both masses. The expression of all three geometry is emphasized with 3 different materials applied to each geometry; i.e. wood, concrete and perforated plate. Materials in the design uses 3 basic materials, namely concrete, wood, and iron. With a composition of the 3 that is almost balanced. Material on the buildings are shown as it is, wood as wood and unpainted concrete, in order to show material honesty in design and give an impression of a more modern building.
