With an area requirement of less than 70m2, reality shows that the current design of social housing apartments mainly by reducing horizontal dimensions is not satisfactory. Narrow functional spaces with no accompanying interior solutions as well as no natural lighting and ventilation capabilities have greatly affected the quality of social housing. Current designs which do not aim to be typical for mass production of components, structures, or apartment interiors also make the cost of social housing investment unsatisfactory payments by beneficiaries. The synthesis of factors affecting social housing apartments such as natural conditions, socio-cultural, economic, technical conditions and specific regulations can develop principles for social housing apartments. Those principles are the most important approach to obtaining appropriate social housing solutions and models. Key words: Social housing; social housing apartments; impact factor; spatial design principles.
