Decerto is a minimalist house located in Warsaw, Poland, designed by MFRMGR & Moko Architects. The main idea of this project was to create a pleasant and comfortable place of work for many people. The space which we had to rearrange was an existing interior of a commercial building with typically furnished offices. Before, nobody considered the needs of the employees and how they felt while working in such interiors. The plan was based on the modularity principle which aims at arranging the space to create as many workstations as possible. The interior design completed according to the typical office standards did not contribute to creative atmosphere of work due to its lack of humanity.
