Mansion of the Sun or Château du Soleil was inspired by the finest traditions of 18th century French architecture. A gated entrance introduces the estate which spans over 3.8 acres in the heart of the revered Langley Farms neighborhood, distinguishing it as one of the largest estates in this storied enclave.  A gracious driveway leads through meticulous gardens and specimen trees to reveal the 22,000 square foot, limestone and brick mansion discretely positioned on the top of the hill.   Massive wrought-iron doors introduce the interiors which are both grand in proportions and finishes. An impressive plaster dome soars above the foyer and hints at the intricate plaster molding and custom finishes found throughout the home. Italian marble blends seamlessly with contemporary white oak hardwoods and forged iron railings. Throughout the estate, dozens of custom crystal chandeliers illuminate throughout the expansive and open floor plan.  Positioned across the entry hall, the richly paneled library would be right at home as the centerpiece of an Ivy League Club.  Just beyond, the grand ballroom appointed with floor-to-ceiling mirrors was inspired by the opulence of the Palace of Versailles. Upstairs, the primary suite spans a total of 3,300 square feet and boasts panoramic views of the pool and the gardens beyond. Not to be overshadowed, the primary closet encompasses 1,100 square feet and spans two levels with the finest Italian cabinetry and custom lighting throughout.  The nine additional bedroom suites are also gracious and include ensuite baths featuring stunning mosaic work and beautiful views of the gardens.  Separate guest or staff quarters are discretely positioned above the garage. The list of amenities continues elsewhere in the mansion: a spa with a massage room, sauna, fitness center, private hair salon, safe room, three wet bars, four kitchenettes (in addition to a main and spice kitchen) a wine cellar, card room, and a professional home cinema are among the amenities in this luxurious retreat. A full-service elevator accesses all four levels of the mansion. Outdoors, expansive terraces overlook a modern lap pool surrounded by dancing fire bowls, fountains and a dramatic waterfall. A fire pit, separate cabana, and a 250-inch outdoor television provide yet another dramatic venue for outdoor entertaining. Extensive landscaping includes a large koi pond, jogging path, and a French garden inspired by palaces in Normandy. Behind the scenes, commercial-grade equipment allows the entire estate to be self-sufficient and secure; a full-house generator ensures continuous power.  Smart home technology equipment controls lighting, the sound system, HVAC, and security systems and can be controlled via voice activation anywhere in the world. Ten HVAC zones provide separate thermostats for each bedroom, and 30 cameras around the fully-fenced and gated property provide an additional layer of security. After the sun sets, 350 landscape lights illuminate the estate, and a full irrigation system keeps the landscaping lush and verdant. For the car enthusiast, there are five stacked parking spaces available — enough to house a collection of ten automobiles. An additional, separately deeded building site within the estate provides room for a separate guest house, gatehouse, and 30 additional parking spaces. Situated an equidistant and just a mile from the George Washington Memorial Parkway and the Capital Beltway, convenience is part of the equation as the estate is only 15 minutes from the White House, embassies, fine dining, and entertainment venues in Washington. World-class shopping at the Tysons Galleria is less than ten minutes away.  The mansion is in the very final stages of construction and scheduled for completion in Q1 2023. Unquestionably, Château du Soleil is a rare example of uncompromising luxury and one of the finest properties ever to be offered in the region.
