The modern property No. 12 on Mira Avenue, formerly known as 1st Meshchanskaya Street, consists of three buildings erected in different eras. Closest to Sukharevskaya Square is the recently restored 18th-century carriage house located in the courtyard (d. 12, bldg. 9), adjacent to a service building facing the street (d. 12, bldg. 3). Next to it stands the main two-story house, which retains the chambers of the 17th century (d. 12, bldg. 2), as well as a three-story building from the late 19th century, reconstructed from a one-story wing (d. 12, bldg. 1). This property is often associated with the name of General Field Marshal Yakov Vilyamovich Bruce, a companion of Peter I and a scholar who was considered a 'sorcerer and wizard' in Moscow. However, the history of the property traces back to the 17th century and does not include Bruce, which does not diminish its historical value.

In 1675, merchant Ivan Isaev acquired part of the current property No. 12 from the trader Kuzma Grigoryev. In the following years, he expanded his holdings by purchasing neighboring plots. Thus, the boundaries of the current estate were formed, which remained in the Isaev family until 1777.

Ivan Isaev, the founder of a merchant dynasty, was originally from the Belarusian town of Dubrovna. He was captured during the Russo-Polish War of 1654-1667 and was brought to Moscow, where he became a serf. After the Treaty of Andrusovo, he was freed and settled in the Meshchanskaya sloboda, engaging in trade. Having become wealthy, he became a member of the merchant hundred. His son, Ilya Ivanovich, held the positions of president of the Main Magistrate and vice-president of the Commerce Collegium.

Under the Isaevs in the late 17th century, stone chambers were built, which were repeatedly reconstructed but retained the brickwork of the 17th century, cellars made of white stone with stoves and hooks from doors. The southern and northern facades have been restored with the window frames and decorative elements of that time.

In the second half of the 19th century, the estate passed to the Baskakov family. The last owners before the revolution were sisters A. I. Zvonova and O. I. Voznichikhina (née Baskakova).

House No. 12 on Mira Avenue is a federal cultural heritage site.

As for Y. V. Bruce, his property was located on a different plot of 1st Meshchanskaya Street, the modern property No. 34, where historical buildings have not survived.
