In 1928, the Müllers purchased a building plot in Prague 6 – Střešovice. They applied for a villa project through the Pilsen architect Karel Lhota, a well-known architect of Adolf Loos. In October 1928, Dr. Müller concluded an agreement with both architects, Adolf Loos and Karel Lhota. In November of the same year, he applied for a building permit. The issuance of the permit was accompanied by a number of difficulties and the negotiations dragged on. Although the main reasons for the long negotiations were primarily technical, there were also objections that the villa would be taller than the surrounding buildings. Doubts were even expressed as to whether the villa’s too smooth facade would be disturbing in the surrounding villa buildings. As late as April 1929, the city council decided that the permit would not be issued, although the Müller-Kapsa company, entrusted with the project, had already begun the rough construction.

Dr. Müller repeatedly appealed against the refusal to grant a building permit. The difficulties in dealing with the authorities became public knowledge when the Prague German newspaper Prager Tagblatt published the article "Prague against Loos". This was at a time when Dr. Müller's appeal was already being discussed by the provincial office. Finally, after reviewing all objections, a building permit was issued to Dr. Müller in June 1929.
