The article presents an analysis of the current calculation of the density of residential buildings, its influence on the further calculation of the territory for the functioning of residential buildings. The article also hypothesizes that residential buildings should have different types, which in turn should affect the calculation of its density. The article presents theses of the importance of building density, its impact on the environment and people's lives. Examples of various residential buildings, their functionality, and the typology of apartments and apartments are also given. In Ukraine, the density of residential buildings is calculated according to a single principle, according to the urban planning department. Regardless of any socioeconomic, geographic, or market factors. That is, the calculation of the number of residents is accepted in accordance with DSTU [24], in residential buildings the number of people who are permanently in the facility (L/f is determined according to the norm of 21 m2 of total area per owner (lessee) of the home and each member of his family and an additional 10.5 m2 per family. The article proposed: Modern trends in urban development dictate new rules to which the market responds, but architectural standards do not. It is safe to say that the modern housing development of Ukrainian cities is not uniform and can be divided into the following categories: Family-type residential buildings of medium storey, with a predominant amount of appropriate infrastructure, such as playgrounds, educational institutions, etc. Residential construction of the business segment as part of a multifunctional building. Where the vast majority of residents use this building exclusively for recreation and spend most of their time next to the public building. In my opinion, this type of residential development definitely does not need playgrounds in the same amount as a family building. Residential development for students and young professionals. There is also a completely different need for infrastructure and a different approach to the density of such buildings. Country-type residential building, recreational, up to 4 floors. Usually, such a building has socio-economic features such that it is located outside the city, has a high level of motorization, but at the same time it is usually located near large areas of nature, forests, reservoirs, which already partially become part of its infrastructure. The main examples are: Fayna town residential complex, Unit city, MIT campus and Park lake city residential complex, each for every social economic factor.
