24 municipalities were added to Brno on 16th of April 1919 and the area of the city expanded from approximately 1,730 to approximately 12,380 ha. Through this administrative expansion so-called Large Brno emerged, creating in turn both theoretical and practical space for Modern construction. Brno became the capital city of Moravia in the newly emerged Czechoslovakia and one of the most significant economic centres and communication axes in the country. The status of a regional capital amounted to the initial basis for a building boom for Brno with this taking place over the following two decades. The period demarcated by 1919–1939 was only a short period in the construction history of the city, however, the quantity and first and foremost the quality of the newly emerged structures had never been and has still not been surpassed. The earlier provincial, mainly German industrial city with strong ties with Vienna, became an important economic and administrative centre with a majority Czech speaking population. Seats for central administrative offices were built along with political, scientific, cultural and educational institutions. The natural growth as well as influx of new inhabitants led to extensive housing construction. These circumstances became a unique opportunity which was not wasted in the case of Brno. On the contrary, ideal conditions were created here for intense development of a distinct building culture.
