A small two-story mansion with a mezzanine, located slightly off the bustling Spartakovskaya Street, could tell much about its owners.

Until the mid-19th century, the plot on Pokrovskaya Street with a large garden and a small gentleman's house belonged to the Gildebrandt family. Several generations of this family, known for their medical profession, lived in Lefortovo in this house. The first to arrive in Russia was Johann Conrad von Gildebrandt, born in 1747 in Arensburg on the island of Saaremaa. In Russia, he was known as Ivan Karlovich. He lived in Moscow until 1831, working as a military doctor. In 1771, he participated in the "campaign against the departed Kalmyks," and in 1774, during the siege of the city of Uralsk, which was defending itself against Emelyan Pugachev's troops. His nephew, Fyodor Ivanovich, also became a doctor, was a professor of surgery, and a renowned operator in Moscow, authoring books on eye treatment. Fyodor Ivanovich's son, Ivan Fyodorovich (1806-1859), graduated from Moscow University, worked there as an adjunct to Professor Inozemtsev, became a surgeon, and earned a Doctor of Medicine degree.

In the 1870s, the estate was acquired by Pyotr Semyonovich Galtsov, a trusted person of the Malyutin merchants and the main manager of the commercial part of the Malyutin textile factory in the village of Ramenskoye, Bronitsky district of Moscow province.

Pyotr Semyonovich began his career as a clerk and held the position of commercial director of the factories for 40 years. His son, Semyon Petrovich Galtsov, continued his work, employed at the company "Malyutin and Sons" and lived in a house on Yelokhovskaya Street with his brother Sergey.

On the eve of the revolution, the house was acquired by Boris Mitrofanovich Serikov, director of the Central Joint-Stock Company for Cement Production and owner of the trading house "B. Serikov, E. Ringel, and A. Starostin." The house belonged to his wife, Nadezhda Ivanovna.

Boris Mitrofanovich Serikov was one of the founders and a key figure in the establishment of the Voskresensky Cement Plant, which celebrated its centenary in 2013.
