Bolshoy Gnezdnikovsky Lane 10, Art Nouveau building in Tverskoy District, Moscow, Russia.

The Nirnzee House at Bolshoy Gnezdnikovsky Lane 10 is a nine-storey apartment building completed in 1913, shaped like the letter P around a corridor system with four lift shafts. Its facade mixes Art Nouveau, Constructivism and Neoclassicism: rows of windows divided by vertical red strips, five bay windows, and a top floor with vases and flower garlands. A pediment carries Alexander Golovin's mosaic panel with swans.

Ernst-Richard Nirnzee built the house in 1912–1913 as Moscow's tallest residential building, after the construction commission tried to cut one storey and he proved the structure could bear the load. In 1915 he sold it to banker Dmitry Rubinstein for 2.1 million rubles. In October 1917 it was a White Guard stronghold and was taken on 28 October; in July 1918 it was nationalized and nicknamed the Fourth House of the Mossovet.

The house is nicknamed Tucherez, "cloud-cutter", for its height, and its top is crowned by a ceramic panel with swans by artist Alexander Golovin. Metal flower boxes designed by Nirnzee survive on most windows; he intended the facade to come alive with flowering plants in warm weather.

The building stands in a narrow, curving lane, so Nirnzee widened the stairwells on every floor to let rescue equipment through in case of fire. Apartments had high ceilings but no kitchens; a floor attendant on each level ordered meals from nearby taverns and restaurants. A shared kitchen installed in Soviet times served residents until the mid-1980s, after which small kitchens appeared in all flats.

The building's nickname, "Tucherez" (cloud-cutter), came from its record height. In 1915 a film pavilion for winter shooting was set up on the roof by the Kinochaika partnership, founded by V. Gardin and V. Vengerov. During the Second World War anti-aircraft guns on the roof defended against air raids.
