Versailles house, Châteauesque mansion in Windermere, US.

Versailles house is a châteauesque mansion in Windermere, Florida, covering 90,000 square feet (8,360 square meters), with marble walls, Brazilian mahogany windows, and multiple indoor and outdoor swimming pools. The rooms spread across several levels and include nine kitchens and fourteen bedrooms, among other spaces.

Construction began in 2004 but was interrupted during the 2008 financial crisis when the property was listed for 65 million dollars. Work resumed later, though the project remained unfinished for many years.

The house takes its name from the Palace of Versailles in France, and its story reached the public through the 2012 documentary The Queen of Versailles, its 2024 theatrical adaptation and the Discovery+ series The Queen of Versailles Reigns Again (2022). The Siegels' children grew up during construction, so playrooms were converted into a yoga studio and a teenager's cave with a second movie theater.

Versailles is a private residence under construction, not open to visitors; the property sits behind a green chain-link fence at 6121 Kirkstone Lane in the gated Lake Butler Sound community. It can only be seen from the public road, and the house remained unfinished as of July 2024.

The ballroom floor displays a butterfly pattern in memory of Victoria Siegel. The living room was designed to recreate the interior of a private passenger cabin on an aircraft.
