Hajnova vila, Functionalist villa in Vysočany, Prague, Czech Republic

Hajnova vila is a one-storey functionalist family house on sloping ground in Vysočany, Prague 9, with a flat roof, large windows and a plain facade. Its roof carries a small glazed lookout, the "captain's bridge", from which Miroslav Hajn watched aircraft take off at nearby Kbely airport.

Architect Ladislav Žák designed the villa, built between 1932 and 1933 for Miroslav Hajn, co-founder of the aircraft company Avia. It has been a protected cultural monument since 1958. The current owners bought it from Hajn's widow in 1964, and it has remained a private home.

Miroslav Hajn, co-founder of the aircraft maker Avia, had the villa built as a family home, and its roof "captain's bridge" let him watch take-offs from nearby Kbely airfield. The house stayed in private hands: the present owners bought it from Hajn's widow in 1964, and it is still lived in today.

The villa stands at Na vysočanských vinicích 31 in Vysočany, Prague 9. It is a protected cultural monument and a private residence, so it can be viewed from the street but not entered. The sloping street allows views of the facade and the rooftop "captain's bridge".

The roof includes a specialized viewing platform designed for watching aircraft from the nearby Kbely Airport. This feature highlights the owner's close ties to the aviation industry at a time when flying was still a new technology.
