The fabric of the brick villas is supported by countless steel carriers, most of which are set vertically in the floors on the first storey. These are not, however, autonomous steel frames, even if the brick skin does not in itself have any support function. Individual cubic units seem to be fitted together like boxes, with individual segments of space interlocking inside. Viewed from the street, the buildings seem fairly self-contained and compact. But from the rear the cubic elements can be seen to be stepped, consisting of ever-increasing volumes going from the narrowest side in the west to the widest in the east. Source
