The increased demand for residential space is in constant conflict with available spatial resources. Utilization of unbuilt urban land for residential purpose is faced with two opposing extremes – development of single-family housing in peripheral urban areas, on one hand, and the insertion of multi-family housing as infill in central urban zones, on the other. A contemporary approach to housing development turns towards the application of low-rise high-density model – as an alternative solution, that tent to achieve the best of both extremes.The research deals with the possibilities of applying a modular system, symbolically named Mix-Mesh, which, through various combinations of the basic module (dimensions 4.2x5.0m) would enable the development of a wide range of residential units – grouped within various typological forms: from two or three-story single-family row houses; combined models of single-family and multi-family housing; to multi-family buildings, which can be developed in the form of gallery or corridor solutions (depending on the shape, dimensions and plot orientation). One of the main advantages of low-rise high-density housing, which is reflected in the presence of significant private open areas, is also present in this model. A specific advantage of this modular solution is reflected in its easy adaptability to different urban parameters and conditions present on a plot, which is obtained through various combination types.

In Serbia, Roma people face various challenges, primarily expressed through discrimination in many fields, as well as difficulties in education, healthcare, and employment. The majority of Roma people in Serbia live in very poor housing conditions. Romani settlements are generally characterized by overcrowded areas, inadequate infrastructure, unplanned construction, lack of amenities in the surroundings and, often, a ghetto-oriented atmosphere. Housing of Roma people, which is the topic of this paper, is a complex topic having various social, economic, cultural and political aspects. The paper considers the Romani housing from a spatial point of view. Provision of housing for the Roma people is one of important ongoing problems that must be addressed by the state. The social and economic status of the Romani national minority could be improved by solving the housing problem. In an attempt to contribute to solving the abovementioned issue, the research deals with finding a sustainable housing model for the Romani population through the case study of the Romani settlement of Crvena Zvezda in the City of Niš: The paper presents an urbanistic-architectural conceptual model for the new Romani settlement on the location occupied by the existing settlement. The model for the new Romani settlement is the result of an architectural analysis of the location and the analysis of the relevant literature that gives a clear view of the state of the Romani population and their settlements in Serbia - their current situation, culture and tradition, habits and needs. The paper gives a proposal for the transformation of the settlement in the form of an experimental conceptual model. The aim of the paper is to contribute to finding an adequate housing model that would provide normal living conditions for the Roma people in a fast, cost-effective, and efficient way, thereby speeding up the processof their inclusion in the society. The modularity and flexibility of the presented conceptual model ensure its applicability in different locations and adaptability to various conditions, making it applicable in different spatial contexts.
