The interior was created in an exclusive house in Vilnius centre built in the mid-19th century. Famous scientists and artists of Lithuania of the Soviet period lived and worked in the house. Special aura is still felt in 124 sq. m. apartment with high ceilings. Thus, we wanted to preserve the decorative profiled edging of concrete ceiling and other elements of the interior of the apartment built during the Soviet period as much as possible. Style and eclecticism of the interior. We wanted to strengthen and supplement the existing classical elements of the interior in the walls by creating contrast with modern elements of volumes and modern furniture today. Contrasts are also used in choosing materials. Such materials as marble or granite which are generally used in classical interiors are combined with concrete finishing or terrazza mosaic concrete texture tiles finishing. The main and particularly contrasting modern accent of the apartment was concrete volume with two bathrooms. Two bathrooms were integrated in the rearranged plan of the premises by extending them to the bedroom but the existing decorations of the ceilings of the bedroom were preserved by means of incorporating the concrete volume. Luminaires of different design are used in the interior, some luminaires are classical, while other luminaires are minimalist and modern. The compositions of some luminaires were manufactured individually for the design.
