The Usad’baricco project combines the traditions of a Russian mansion house (usadba) and a spatial idea of barocco. A bizarre plan of merging spaces is outlined by a square faсade of a chatoyant mosaic of materials. The décor of the faсade is built on the principle of the spatial gradient, involving a smooth transition of one material into another, covering the surface in accordance with the concept and the function. Wood, metal, glass, stone, plastic, solar panels – each sort of material has several types of surface. The plan is built basing on the geometry of ellipses and intermediate spaces. Proportions and sizes of ellipses are connected with the function of premises.
