The new building, Käpylän Posteljooni, which contains 57 apartments, ranging in size from 30 to 120 square metres, takes cues from this moderate modernism and brings it to another level. The building has two faces. On one side, the new U-shaped building is relatively closed. This side, which is facing a relatively busy roundabout is referencing the surrounding early postwar architecture, with its pitched roofs, and stucco facades punctured by identical windows. In contrast to this intentional inscrutability, within the U-shape the building is much more transparent. On this side, the apartments look out over a collective courtyard, designed by MASU Planning, and a more quiet street.
