As if that wasn’t odd enough, the couple got the approval of the Russian courts earlier this year concerning the idea.
Margareta says she didn’t have time or money to build a second staircase before a team of builders instructed by her husband constructed the grey brick wall.
She posted pictures of the wall being built on social media before speaking of the scenario.
“Me and my son were having a breakfast when builders came into the house, dragging in blocks of concrete,” she wrote on Facebook.
“A court official came too, armed with a statement saying that I should have built my staircase by now.
“I showed him the earlier court’s decision that gave me more time,” she said.
The wealthy couple, who have three children together, split in 2010 and have spent much of the last six years in court against each other.
When the divorce was finalised a court ordered them to split their assets 50/50 between them, but their main asset was the house in Moscow, worth around $3.2 million.
Margareta told Russian media they did not want to sell the house as “the Russian real estate market is in crisis” and they wouldn’t have gotten a good deal for it.
