Our one floor office was located in Tangerang rukan which has its limited space. Many functions were needed in this office, such as working desks area for staffs, directors’ room, meeting room, pantry, and break room. We had pantry and break room to give relaxing time for the staffs and lessen their work stress. To ensure the office was not narrow, though it had limited space, we made an open layout concept. Only break room that used closed partition to let the user has privacy. Director’s room used a glass partition to make the interior visual broader, though the user still can have their privacy.
