Prager, born in Kroměříž in 1923, received his higher education at the Czech Technical University in Prague. After a brief period in Ostrava, he returned to Prague and started working for Stavoprojekt. Later, he became the director of Ateliér Gama, which was part of the Association of Project Studios founded by prominent Czechoslovak architects. However, during the normalization period, the regime did not approve of the existence of non-state associations, and the individual studios had to submit to the state. Prager, however, continued to lead his studio. And what place did he consider his home? It was Braník. The villa with a view of Prague may not initially reflect his typical style. The original cubic structure from 1968 was supplemented by his son-in-law, architect Jan Louda, with a roof extension made of a steel shell in the shape of a split cylinder.
