This building is a true architectural masterpiece. Its facade is painted a delicate green, and the arched rotunda along with a variety of architectural styles and ornaments make the Sevastyanov estate unique. It is located by the city pond and is as significant to Yekaterinburg as the Winter Palace is to St. Petersburg. This Ural landmark has even been included in the Central Bank's project "Architectural Monuments of Russia," and its appearance has adorned coins.

Currently, the house is state-owned, but it was previously owned by several private owners, each of whom left their mark on the facade's design. The mansion combines elements of classicism, baroque, and neo-Gothic, and there is no equal to it in the Sverdlovsk region.

The history of the building began with Alexander Razderishin, a mineralogist and the first owner of the wooden house. In 1817, under the new owner, industrialist Ivan Polkov, the house became a stone mansion with a corner rotunda. Polkov, a fan of classicism, sought correct forms and simplicity, which reflected in the architecture of the building that adorned Ekaterininskaya Square.

In the 1860s, the house passed to the office clerk Medvedchikov, who sold it to Nikolai Ivanovich Sevastyanov. The new owner, a hereditary nobleman with exquisite taste, decided to add elements of neo-Gothic and baroque to the classical features. He was assisted by architect Alexander Ivanovich Paduchev, who created the design for the updated house.

Restoration began in 1866. The architect planned to add a balcony and a light extension, but ultimately replaced them with a lace-like loggia in three tiers, which unfortunately has not survived. Along the facade facing the pond, there was a suite of rooms with a staircase and two halls: neo-Gothic and neo-Renaissance. The marble fireplace of one of the living rooms has survived to this day.

After the restoration, the house acquired a fairy-tale appearance with intricate patterns on the facade. There is a legend that Sevastyanov did not live in the house but rented it out, preferring to observe the mansion from a bench on the street. There are also rumors of his intention to cover the dome of the rotunda with gold, for which he was allegedly punished.

Sevastyanov owned the house for 20 years, after which he sold it to the state and moved to St. Petersburg. The building housed the district court, and in the early 20th century, another reconstruction was carried out.

The February Revolution changed the fate of the estate. The mansion was looted, and the court was disbanded. Subsequently, the Ural Labor Commissariat was located here, and later, the regional council of trade unions.

After the restructuring, the building changed owners again and began to deteriorate. However, in 2009, ahead of the Shanghai Cooperation Organization summit, the mansion was thoroughly renovated and became the president's residence during his visits to the Urals.

The Sevastyanov house consists of three floors. On the first, there is a vestibule and a living room; on the second, a cultural and entertainment area with a fireplace hall, a historical hall, and a column hall. On the third floor, there are rest rooms. Excursions are held here for schoolchildren and city guests, where they can see the interiors and antique furniture. The facade of the building is adorned with numerous small details that one can examine all day long.
