About this home
Designed by renowned architect Gary Nance, the custom estate was created for sophisticated everyday living and grand-scale entertaining, while its scale and configuration offer uncommon flexibility for residential or commercial use, including a private estate, bed and breakfast or multi-family concept, subject to applicable zoning and approvals. The interiors feature 6 bedrooms, 10 full baths, and 5 half baths, along with 3 kitchens, 2 theaters, a commercial-grade wet bar, billiards and gaming areas, a private bowling alley and generously sized ensuite bedrooms. The thoughtful layout accommodates multigenerational living, extended family and guests, while also lending itself to a variety of potential uses. Waterfront living takes center stage outdoors, where a spacious deck with docking capabilities creates a natural extension of the property. Spend summer days on the lake, gather for sunset dinners overlooking the water or enjoy the privacy and natural beauty of the setting. A 5-car garage provides abundant space for vehicles, boats and recreational equipment. The opportunity extends beyond the existing estate. Buyers may acquire either or both adjoining 2.5-acre parcels, creating the potential for an expansive private compound or further development. Promontory combines privacy and natural beauty with convenient access to Downtown Zionsville, top-rated schools, dining, shopping and everyday amenities. Buyers may also choose membership at either Holliday Farms or Chatham Hills, 2 premier private club communities offering additional opportunities for golf, recreation and connection. For those seeking a property with private lake access, expansive acreage and extraordinary versatility, 9825 Windy Hills Drive offers a rare combination of scale, setting and potential. Whether envisioned as a private residence, commercial venture, bed and breakfast or multi-family property, the possibilities extend well beyond the traditional estate.
