The Villa Müller (Czech: Müllerova vila, German: Haus Müller) is a Modernist villa in Prague, Czech Republic built in 1930. It was designed by Adolf Loos as a residence for František Müller, co-owner of the Kapsa-Müller construction company from Pilsen.
The building was commissioned by František Müller and his wife, Milada Müllerová. Mr. Müller was an engineer and co-owned a construction company called Kapsa and Müller. The company specialized in reinforced concrete, developing new construction techniques. Loos' method of design was also in transition, making the timing of the project appropriate. Soon, the architect Karel Lhota set František Müller up with Loos to design the Villa, the same way as of the Villa Kapsa. Lhota also contributed to the design due to Loos' poor health. After the building was completed, Loos celebrated his 60th birthday there with a few friends.
