Shortly after he fled Kiev, reporters descended on the lavish mansion of deposed Ukrainian President Viktor Yanukovych, calling the villa everything from a show of "crazy luxury " to a "grotesque monument" to his vanity. It turns out that some of the more opulent detail work at the Mezhzhirya estate was carried out by German companies, SPIEGEL has learned.

Documents secured at the property by journalists include numerous invoices from German companies. Among the details found in the documents is that a Bavarian firm called Butzbach supplied the door used for a helicopter hanger located on the property. An interior design firm called Brunold Innenausbau und Design apparently provided the "installations in the master and madame's bedroom to on the third floor" to the tune of €4.5 million ($6.25 million).

Another document lists the fittings in the pool room, including "half columns" and a window sill with marble insets.

Despite the generous commission, the firm Brunold has since gone bust. According to the company's bankruptcy administrator, the value of Brunold's total work at the villa was in the double-digit millions. The documents can be viewed on the YanukovychLeaks  website, which was created with the help of Berlin-based programmers Friedrich Lindenberg and Stefan Wehrmeyer.
