The proposed building behind Atmoterm’s headquarters is an independent “back-office” facility. It is characterized by a simple and economical design typical of annexed buildings. Access to the building is possible through a passage between the buildings on Łangowskiego Street. The entrance to the building is directly accessible from the ground level. The above-ground floors are designed in a linear layout with a central corridor for communication, conference rooms, and sanitary facilities. The external strips comprise open office spaces, providing complete flexibility in arrangement, ranging from “open space” layouts to individual offices. It is possible to create two, three, or four separate office areas within the building.
