The main directions in the development of this concept were universality and optimality. The planning of two typical houses for one and four families was developed taking into account the universal needs of possible tenants. The common area of the living room with the kitchen, two bathrooms, two bedrooms and the mezzanine area can be used as an additional bed or storage space. This set of premises is as versatile as possible and meets general needs. But in addition, there is always an opportunity to transform the interior of each room. The concept provides for optimal use of materials and maximum simplification of construction. After all, the dimensions of the walls are adopted in accordance with the standard dimensions of the panels, which reduces the volume of waste. The project also uses unified window sizes that correspond to the optimal ratio of price and volume of materials
