For Sale: McLean's Most Expensive Planned Home

Ten bedrooms, 15 bathrooms and more than 6.5 acres of property overlooking the Potomac River. If you throw in eight fireplaces, a swimming pool, an amazing kitchen, marble everywhere and a five-car garage, how much would you pay for it?

The Building Group, Inc., which still plans to build the now-infamous "Le Chateau de Lumiere," is betting someone will pay $45 million for a to-be-built 25,000 square foot mansion at 636 Chain Bridge Road.

Long & Foster posted the above YouTube video showing a virtual tour of the planned home in late January, indicating a new push to market the property.

"Quietly obscured at the end of a winding drive on 6.5 gently rolling acres with park like setting, this magnificent embassy style estate will be perfectly sited to capture the alluring sounds and expansive views of the Potomac River. This ambitious vision by award-winning The Building Group could well be considered the most significant residential estate to be constructed," according to the official listing.

634 Chain Bridge Road, located right next door, is on the market for $9.8 million. That property, built in 1968, once was owned by Sen. Ted Kennedy. Long & Foster presents the property as "a rare opportunity for new construction." It was assessed by Fairfax County in 2012 for $5.4 million. 636 Chain Bridge Road is listed by Fairfax County as vacant land.

Both 634 and 636 Chain Bridge Road are owned by River Song Limited, based in Hong Kong. The properties would be combined to create the 6.5-acre parcel that "Le Chateau de Limiere" would sit on.

The home site is secured with a gate, cameras and an alarm system.

The blog Home of the Rich reports a healthcare entrepreneur, Young Yi, was going to build the home but was unable to do so. The Building Group owns the plans and is still very interested in building the home for the right buyer.

In 2012, The Huffington Post reported neighbors of the planned property were upset that the planned estate would not fit in with the rest of the neighborhood and construction would require cutting down many trees. One neighbor filed a lawsuit over the plans, the Washinton Post reported.

Correction: We have adjusted the address from Great Falls to McLean, and the chateau is spelled Lumiere. Thanks, readers!
