"One of the primary concepts of the project was to attempt to open up the courtyard rather than use it as a second grade source of light that is one of the main problems of the Berlin tenement blocks. All of these are qualities that are not very common in architecture in this city".

Above extract taken from  writings on architecture, urbanism & art blog, defiantly worth a read.
