BROOK Inc. together with HITOBA DESIGN co., ltd. had an opportunity to design an office for Ierae Security Inc., a cyber security service provider. The entrance is designed simply with a modern touch to produce a minimalist taste. The colors in the workspace are limited to black and white with a little bit of green to create an efficient and stylish work environment. The ceiling is left skeleton to make the open and airy feeling to the space. The triangle table in the free space has seats not facing each other so people can concentrate on work without being annoyed with someone’s line of sight. The chairs of the triangle table are different from each other to give some variations for the engineers to enjoy the time in the office.
