Using building materials from all over the United States, the 48,000-square-foot Champ d’Or mansion took five years to build. Constructed on a 25-acre parcel and completed in 2002, it was meant to mimic the Vaux-le-Vicomte chateau in Paris. It cost $52 million to build but the original owners never moved in and it just stood there for years after. Eventually, “The Olana,” as it was named, became a wedding and events venue under Walters Wedding Estates.

Now, it’s set to undergo a significant renovation and expansion. The Dallas Business Journal reports The Olana is set to become a 110-room hotel and spa. The work is also expected to include the addition of villas and a pool building, costing $40 million. Twain Financial Partners is the group behind the renovation.

Work on the The Olana Hotel and Spa began on Sept. 1 and is expected to be delivered in fall 2025.

Duncan & Miller Design is listed as the design firm for both projects.
