The Demidov Estate Museum is an ensemble of three stone buildings in the Empire style, located by the Tagil pond. The estate is surrounded by a small park known as the Demidov Estate Garden. The complex includes the main two-story building and two one-story wings. The central building is adorned with a turret featuring a tall spire and a weather vane. From Krasnogvardeyskaya Street, it appears to be a one-story building, as the entrance leads to the second floor. From the pond side, the building looks like a two-story structure, with the entrance leading to the first floor. On the second floor, there is a spacious balcony overlooking the pond, Fox Mountain, and Old Galyanka. The building is decorated with ornamental elements at the corners and roof joints.

The wings, located on either side of the main building, are small one-story houses closer to the pond. Between them, in front of the main building entrance, there is a paved area with flowerbeds at the corners. All buildings are painted in a yellow sandy color, while the roofs and spire of the main building are made of burgundy metal. A path leads from the main building to the pond, ending at a stone pier, the central part of which serves as a viewing platform with a railing, and stairs descend to the pond on both sides. Along the path and in front of the main building, there are lanterns in an antique European style. From the street, in front of the estate's entrance, there is also a platform leading to alleys in the garden. In the center of the garden stands a concrete sculpture from the Soviet era depicting a naked couple of a young man and woman. The entire estate and garden are enclosed by a metal fence. On the first floor of the main building is the office of the first owner of the estate, mining engineer Foti Shvetsov. The second floor features a presentation hall known as the 'Demidov Hall.' One of the wings houses a kitchen with a cellar, while the other contains rooms for museum staff and security.

The estate was built in the first half of the 19th century by the famous Tagil engineer-innovator Foti Shvetsov, who owned it until 1855. On the General Plan of the Nizhny Tagil District from 1843, the area along the Nevyansk tract is marked as 'Matildino Suburb,' named after the wife of Anatoly Nikolaevich Demidov, the French princess Mathilde de Montfort. The second owner of the estate was Prince San Donato Pavel Demidov.

During the Soviet era, the estate was handed over to the railway workers and used as a Komsomol committee, a rest house, a technical school, a kindergarten, and a sports base. In recent years, the building fell into disrepair, the park overgrew, and the sculpture was partially destroyed. The estate became a shelter for the homeless and dogs, and the building caught fire several times.

In 2012, Nizhny Tagil Mayor Sergey Nosov decided to restore the estate. The Sverdlovsk region allocated 50 million rubles for reconstruction, and 8 million rubles were spent from the city budget on project documentation. Restoration work began in the spring of 2013 and lasted for three months. Since much of the building was damaged, it was decided to dismantle about 70% of its upper part, including the second floor and turret. The second floor was rebuilt, the wings were constructed, paths were paved, new lanterns were installed, and the stone pier was restored.

On September 23, 2013, the restoration of the estate and park was completed, and the 'Demidov Estate' museum was ceremoniously opened. In 2014, the Soviet sculpture was restored.

On the first floor of the main building, there is an exhibition of Foti Shvetsov's office with furniture and portraits. The second floor features the Demidov Hall, decorated with portraits of the Demidov dynasty and items from Kasli casting. In 2015, an exhibition of author's porcelain was held here.

The southern wing is open to visitors, where one can see 19th-century kitchen utensils. The estate museum also hosts presentations, buffets, promenade walks, and vernissages, attracting photographers from all over the country.

After reconstruction, the Demidov Estate Museum has become a popular place for recreation and cultural events for the residents of Nizhny Tagil.
