The house belonged to Roman Andreevich Diederichs, the son of one of the owners of the oldest piano and grand piano manufacturing factory in Russia, "Brothers Diederichs." The project was approved by the owner and implemented, but over time R. Diederichs wanted to change the building's facade. In 1914, A. Bubyr most likely sought help from architect N. Vasiliev. This is not definitively known, but A. Bubyr often worked together with his friend. As a result, the building's exterior features a blend of Art Nouveau and Neoclassicism. The project modification was retroactively approved in December 1914, when the private construction department of the city administration permitted "the continued existence of the building, erected with a modified facade contrary to the plan approved on April 6, 1912."
The building is in fairly good condition; the doors were originally severely damaged, and most of them were replaced with metal,
but even then, the upper part preserved images of owls. The doors have now been fully restored.
