This building on Ostozhenka in Moscow is surrounded by many interesting myths and legends related to its unusual architecture. On the roof of the house is a dome in the shape of a bell, resembling an inverted glass. The house belonged to merchant Yakov Mikhailovich Filatov, who founded a company selling plumbing and electrical goods.

Despite a successful business, Yakov Mikhailovich had a penchant for alcohol, which grew over time, and one day he nearly lost his company due to drinking. After this incident, he decided to quit alcohol and allegedly ordered the architect to install an inverted glass on the roof as a symbol of a new sober life. According to another version, Filatov was an Old Believer, and this architectural solution emphasized his adherence to traditions, as Old Believers were sometimes excommunicated from the church for their addiction to tobacco and alcohol.

However, both of these versions raise doubts among Moscow researchers. Firstly, the design of the house was handled by two different architects. Ernst-Richard Niernsee, a supporter of constructivism, built the lower part of the building, while Valentin Dubovskoy, a fan of pseudo-Gothic modernism, worked on the upper part from 1907 and decided to install a massive dome. Secondly, the glass-shaped dome was not a novelty for that time; it just happened that this example was more noticeable.

In addition to the glass, the house features other architectural peculiarities. Its facade is adorned with images of mermaids, fish, and sea monsters. After the October Revolution of 1917, the building was converted into communal apartments. During the last restoration of the Filatov house, the original glass was replaced with a copy.
