Benois House, Apartment building on Kamennoostrovsky Prospekt, Petrogradsky District, Saint Petersburg, Russia

Benois House is a neoclassical apartment complex on Kamennoostrovsky Prospekt in Saint Petersburg, built 1912–1914 for the First Russian Insurance Company to designs by Leonty, Yuly and Albert Benois with Alexander Gunst. Its light grey-beige facades are clad in Swedish talc schist, with rusticated lower floors, pilasters and pedimented windows; the entrance courtyard is framed by a double Doric colonnade of red Gangut granite. The complex holds 250 apartments, 25 numbered entrances and more than ten courtyards.

The First Russian Insurance Company commissioned this residential complex in 1910, with construction completed two years later in 1912. The project arose during a period of major urban growth, when the city needed modern apartment buildings for its expanding population.

The structure takes its name from the Benois family, who produced several generations of notable architects in the city. Julius, Leontiy and Albert Benois worked together on this neoclassical design, reflecting their family tradition of architectural practice.

The building was equipped with advanced facilities for its time, including steam heating, electric elevators and a telephone station. Visitors can view its exterior architecture from Kamennoostrovsky Prospekt and the adjoining streets.

The attic of Benois House sheltered a colony of homeless children in the 1920s; after they were evicted, they set fire to the attic in the winter of 1927. The composer Dmitri Shostakovich lived in apartment 5 on Bolshaya Pushkarskaya Street from 1937 to 1941 and wrote the first three movements of his Seventh Symphony there.
