Storey Addition with Bricks

A project involving the renovation and addition of a storey to a listed office building in Leipzig has received several awards as ­a positive example of inner-city redensification and for the mixture of residential and office use. For the storey-addition of a former celluloid factory, Knoche Archite­kten used Poroton S9-MiWo bricks with a wall thickness of 36.5 cm and high thermal insulation as well as brick mounted ceilings from Wienerberger. ­A thermal insulation composite system was therefore unnecessary. Steel girders transfer the loads to the load-bearing outer and inner walls. The superstructure clearly stands out from ­the existing building in terms ­of ­colour and design. The irregular sequence and dimensioning ­of the windows, which at the ­same time incorporate the ­vertical edges of the existing ­windows, emphasize both the connection and autonomy of ­the new storey. The architects dispensed with both projections and balconies. At the roof edge, they continued the horizontal structure of the ­existing building, and applied a comb plaster ­to the outer walls with 15-mm-­deep joints. The joints run horizontally like the bed joints of ­the masonry.
