He studied at ČVUT, where he also received his doctorate in 1931. He then founded an architectural studio with Josef Kittrich. Together they designed several projects in Prague, as well as in the Czechia and Slovakia. After the Second World War, he co-worked with Kittrich once again. When the communist party came to power in 1948, Hrubý became the head of the state building institution Stavoprojekt. He managed to continue the international trends of modernism in Czechoslovakia. In 1956, for example, he built the House of Fashion (Dům módy) on Wenceslas Square in Prague, and in 1958 he designed the Czechoslovak exhibition pavilion and restaurant for the Expo 58 in Brussels. These buildings received the Golden Star Award for the best architecture. The Expo 58 style continues to shape design in Czechia to this day.
