“…Such developments, however, mainly refer to suburban areas that existed in the Victorian era and to inter-war suburbanisation. These suburbs, formed of semi-detached houses, were established in the immediate vicinity of the cities, forming their outer ring (Frey et al, 2006;Mace, 2009) and, in the course of the territorial development of the city, have become their most inherent parts (Whitehand and Carr, 2001). The dynamic territorial expansion of cities in the 19 th and 20 th century, by incorporation of the surrounding areas (formal extension of city boundaries), which was typical for CEE cities, contributed to the formation of 'suburbs within the city' (Jindrich, 2012; 2019; Szmytkie and Krzysztofik, 2019).…”
