Construction began in 1924 , with the first buildings designed by several architects including Antoni Jawornicki , Aleksander Sygietyński , Wacław Weker and Teofil Wiśniowski , in the neoclassical style . By the 1930s , however , a more modernist style was incorporated into the estates design . During the Warsaw Uprising , between August 4 and 25 , 1944 , residents of the estate were embroiled in the so-called Ochota massacre , a series of mass murders , robberies and other crimes perpetrated primarily by the S.S. Sturmbrigade R.O.N.A. , an anti-partisan group from Russia . An estimated 10,000 Ochota residents were murdered during this period
