It cost approximately $140 million to build, according to a spokesperson for Vladislav Doronin, who commissioned the home.Doronin is the billionaire founder and chairman of real-estate development firm OKO Group and owner of luxury resort chain Aman. Instead of its futuristic nickname, Doronin refers to the home as the Capital Hill Residence.The first design visuals of the home were seen in 2008, but it wasn't completed until 2018, two years after Hadid died.Rublyovka is an ultra-exclusive, leafy suburb that's home to government officials and old money, where homes can cost up to $80 million, according to Leonid Nikitskiy, the head of country real estate at Moscow Sotheby's International Realty.In their business dealings, the two became friends, Doronin said in a 2018 interview with the Financial Times. Hadid referred to him as the Russian James Bond.After Doronin bought the land in the forest, he asked Hadid to design him a house there.We had lunch at the Wolseley in London and I asked her to build my house, Doronin told the Times. I said, I want to wake up in the morning and not see anybody, just to look over the top of the trees. 'She drew a sketch on the napkin and I said, 'You're hired.'She wanted this skinny leg, he told the Times. The contractors and engineers said, 'We can't do this' — but she was right.

And I said, 'Yes.'Source: DezeenSource: Architectural DigestAccording to Dezeen, the home's lowest level includes leisure facilities. Doronin told the Times that the partially-underground section of the home features his very own nightclub.On the ground floor are the living room, kitchen, a lounge, and the swimming pool.
