The building of the Reformed School was one of the most modern for its time due to its equipment and design. Innovative teaching methods were also implemented here, which persisted into the Soviet period. Notable figures such as poet V.M. Gusev, polar explorer E.T. Krenkel, pianist L.N. Oborin, film director E.L. Dzigan, and bard and playwright A.A. Galich studied at the school located in this building.

The Evangelical Church School is part of the architectural ensemble of the 19th and early 20th centuries, which shapes the development of Bolshoy and Maloy Trikhsviatitel'sky lanes. The school building defines the compositional and planning structure of the block.

The volumetric-spatial composition of the U-shaped three to four-story building with a semi-basement, built in 1913-1914, as well as numerous architectural elements and interior details, are protected as a cultural heritage site of regional significance.

The Reformed School, which functioned as a gymnasium, was founded in 1908 by the parishioners of the Evangelical-Reformed Church. It had three preparatory and eight main classes, and boys and girls were taught together, which was a novelty at that time. Admission was granted without restrictions based on nationality or religion, and uniforms were not required. The first three graduating classes were small, with the first consisting of only 12 students.

Initially, the Reformed School was located at the corner of Pokrovka and Armenian Lane, but soon it became cramped in the small two-story building, necessitating expansion. A new three-story building was then constructed next to the Reformed Church, designed by architect Adolf Ernestovich Erikhson.

Erikhson, a Moscow resident of Swedish descent, was a member of the Evangelical-Reformed Church community. In 1891 and 1896, he worked as an architect for the Moscow Treasury Chamber and designed Prechistenka, Tverskoy, and Nikitsky boulevards, as well as the square around the Cathedral of Christ the Savior. His projects included the building of the Central House of Architects and the building of the Society for Printing, Publishing, and Book Trade of I.D. Sytin.

The first director of the school was Anilina Pauner, followed by educator and mathematician Martin Berg. The building featured spacious, bright classrooms, a gymnasium, and physics, chemistry, and natural science laboratories equipped with everything necessary.

During World War I, a hospital for the wounded was opened in the school in 1915, while classes for students were held at the Practical Academy on Pokrovsky Boulevard. During the Soviet era, the school was nationalized and changed its numbers several times: 42, 43, 24, 35, 327, 1227. Currently, the building houses a branch of school No. 2095 with an in-depth study of the English language.
