As early as in the ancient Rome plants were cultivated in flowerpots situated on terraces (solarium), they were also a part of atrium, inner yard, where they have excellent conditions for their growth. In European residences of nobilities the roof terraces with many flowers could be often found, especially with citruses. Nowadays man develops conditions for plants also on the positions where they don’t grow naturally – on the roofs of not only dwelling houses, but also of hotels etc. The interconnection of the exterior and interior can be realized only by winter gardens that create the transition between particular forms of residential space.
