One of the best examples of residential construction of the period of Moscow Empire style - house constructed by D. Gilardi for prince Gagarin - distinguishes with its original dimensional and facade composition. A tight, strictly symmetrical, not linked by outhouses dimension of the construction is moved a bit back from the building line of the street. The architecture of the main facade shows the temperance of the Empire style. The ground floor is decorated with rectangular rustication, the main motive of the Empire style - lion masks - could be found in the keystones of the windows. Lateral walls are almost without any decoration. Centre of the facade is marked with a small risalit and a flat fronton. Here Gilardi abandons traditional portico and uses an arch form with plastically rich architectural and ornamental decoration.
