The new building comprises two residential towers with three maisonette flats contained in each one, a central stairwell in the area between the towers, as well as two-storeyed terraces belonging to the respective flats. On the lower maisonette level, the flats are accessible via a draught lobby that is glazed on both sides. Above it, an open passageway serves as escape route from the upper storey flats to the stairwell. Glass-block walls and -parapets fringe the terraces allowing a vista from the inner court to the outer areas.
