Crime, theft and vandalism is a common problem occurring in urban areas [1]. As shows previous research, Crime Prevention Through Environmental Design (CPTED) is an effective tool [2], which helps to create safer environment. Being already tested in different types of housing neighborhoods, on public transport stops, metro stations and even parks, implementation of CPTED principles hasn’t been researched in relation to urban allotment gardens, which, however, in certain countries often face problems of theft and vandalism. Based on this data, this paper aims to examine whether there are any of CPTED principles implemented in urban allotment areas and whether environmental design solutions can help to decrease crime on these sites. This paper presents the investigation (observations, evaluation and interviews) of four allotment sites in Riga and four sites in Warsaw. Results of this research show that, effectiveness of various environmental design tools differ in Riga and in Warsaw. However, implementation of complex CPTED solutions ensures creation of safe environment in both cases.
