Gunnard Asplund, Acceptera, 1933

“If we will demand residents of equally high hygienic standard for all, then the requirement of direct access to sunlight for all dwellings will come to give the new residential areas a completely new character. It is, therefore, a necessity to have an open building principle with parallel buildings positioned according to the sun: east-west in the case of through-going apartments, otherwise north-south. The first-named type of building has, however, the advantage in that it permits cross ventilation and gives the residents a truly effective sunny side.”
