The city is the superordinate system. The buildings always serve the whole and form a community with the urban space. Streets, squares, alleys and parks — in them we move and that is the experienceable city. The core of a building task is the design of the separation from the private interior to the public space. The separating element is what creates the space, what makes it legible. And it must be readable by all people. Then it will be perceived as “beautiful”. In this respect, Lederer is conservative: warm materials, earthy tones, perforated façades and handcrafted details immediately bring us closer to his architecture. Sculptural elements such as bay windows, his special zigzag windows, organic shapes, portholes, gargoyles make the buildings unique and he is not afraid to integrate into the urban context by quoting architecture. Not very “modern”? No, but modern more in the tradition of an Erich Mendelssohn, elegant, dynamic, and also a little playful.
