Avtovo's unique and highly ornate design features columns faced with ornamental glass manufactured at the Lomonosov factory. Although glass was originally supposed to be used on all of the columns in the station, white marble was substituted on some due to time constraints. This marble was supposed to be temporary, but it has never been replaced. The walls are faced with white marble and adorned on the north side by a row of ornamental ventilation grilles. At the end of the platform is a mosaic by V.A. Voronetskiy and A.K. Sokolov dedicated to the theme of the Leningrad Blockade during the second world war.
Unlike the other stations on the first line, Avtovo is a shallow-level station and was constructed using the cut and cover method. It belongs to the shallow column class of underground stations.
Avtovo's entrance vestibule is a large Neoclassical building with a domed cupola, located on the east side of Prospekt Stachek.
