The Bla Bla Car office in Warsaw has a surface of 600 sm. The interest to maintain the height of the floor of 3,4 m leads to the decision of leaving technical installations, air ducts and lights exposed, discarding the option of a suspended ceiling above the open space. The plan presents three closed volumes to divide the space in three main zone: the public entrance with a cafeteria and two work open spaces. The closed volumes include a large meeting room for 18 people and other smaller meeting rooms, a private office, and a break area. All service spaces are concentrated along the existing central cores in order to keep the open space completely dedicated to working activity.
