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.
