One of the oldest houses, which overlooks the main facade on St. Isaac's square is home Malevich, which is a monument of architecture of classicism. It lived historical figures: Lev A. Naryshkin; after his death the house was owned by his son; then it became the owner of Ivan Petrovich Matlow – known Russian poet. This house was visited by A. S. Pushkin, M. Y. Lermontov. Heirs Malevich passed the house of E. V. Bogdanovich – the hero of the Crimean war. After the revolution the house was occupied by the art Museum. He was later reorganized into the Institute. The Institute lasted until 1927. When the war ended 1941-1945, the building was given for the establishment of "Lenstroymaterialy".

City mansion Malevich forms a complex which includes an outbuilding and the main house. The feature of the angular location of the land on which stands the manor house, influenced the choice of the structure of the Foundation. The Foundation consists of two parts: one part of the quarry, the second belt. The ground floor has a limestone finish, this was applied, the so-called "Putilov plate". The so-called plates, are made of limestone mined in a quarry near the town Putilov. Walls built of brick, covered with plaster. In the mansion there are two kinds of slabs: wooden beams form a flat slab, and brick – vaulted. The floors in the building is also of two types: there are simply stone and tiled flooring. This dualism in architecture ends. All Windows have a standard form of the rectangle. The roof is covered with iron. The building itself is very high, the extra height to three floors adds quite a high base. The building has a rectangular shape, with a projection (protrusion along the entire height of the structure, which is beyond the facade and forms a single whole with the construction) in the yard semicircular. Due to the projection, the building has a unique look and is on a par with the Finland station, St. Petersburg mint, known for its avant-corps. The outbuilding also forms a rectangle and has three floors.

Beautiful view of the facade of the mansion is from St. Isaac's square. Window openings on each floor is decorated differently. Ground floor Windows are decorated with smooth frames and sills are fastened by means of brackets. The bas-reliefs above the window openings, made in the form of sculptures on the ancient theme of a rectangular shape and men's textured round shape profiles. The two images above the Windows are alternate. On the second floor trim by the Windows – simple profile, they are decorated with garlands and keystone, which have a volute shape. Further, above the second floor Windows is a frieze, above it is a cornice. On the third floor Windows are square, framed with profiled frames, horizontal elements which rastrepany, this technique in architecture was widely used in the days of ancient Rome.

In the center of the building is the entrance, made by a portico: a balcony over the entrance on the second floor, supported by two pairs of columns without flutes, the so-called Tuscan order. Balcony restricts wrought-iron fence. Balcony door with two sides is the framing of a series of panels of rectangular shape, the reliefs on panels – carved. Right above the doorway is a semicircular shape, surrounded by sculptural elements.

Domestic premises have a perimeter layout. Through the entire second floor stretches front Suite. Now it is impossible to judge how were decorated interiors in the building during the construction, they just did not survive. You can only make assumptions on the individual remaining to the details, which miraculously survived to our time. In the front hall of a rectangular shape, the walls of which are processed by a pair of pilasters, and at the end of the colonnades is four columns. A set of lobby – korbuly. From the lobby goes three-flight staircase. Stairwell semicircular shape, it is corbel. Originally the second floor of the building was intended for ceremonial rooms, which were spacious hall, with galleries supported on pillars. Decorated the hall with marble pilasters. Some rooms have survived the furnace, lined with tiles.

Currently the building is occupied by the city Prosecutor's office and the building was used for its purposes: the room is divided into cramped offices, redevelopment corridors significantly narrowed.
