And not just any house. The building located just outside the Russian city features a futuristic style, and many believe it looks like a spaceship.

The unusual house, which is dubbed Capital Hill, looks like it could be a tool to take over the universe, both on the exterior and the interior.
Russian entrepreneur Vladislav Doronin has been dating the British supermodel since 2008, and reportedly plans to live in the mansion after they get married.
It features gigantic glass panels, smooth curves and extremely tall ceilings.
The 2,650 square meter house will have many luxuries, including a Finnish spa in the basement, a Turkish bath and a Russian bath where the 42-year-old supermodel can pamper herself.
Of course, it also has its own gym and indoor swimming pool that can reportedly turn into a dance floor should the couple want to entertain guests in the evenings.
Two large white towers are situated on top of the building, about 20 metres above the ground, which are said to be the couple's bedroom.
The house that resembles something out of TV's Star Trek is surrounded by a pine forrest, so the lovebirds will be ensured some privacy.
It's not the first time Naomi's lover has built her a house. Last year, he bought her a vacation house in Turkey which looked just as unusual as the new mansion.
And Vladislav clearly has a penchant for odd looking buildings. The vacation home is situated on one of Turkish islands has 25 rooms and is shaped like an Egyptian eye.
