Built in 2007, the upcoming featured property for Alex Thornhill and Stephanie Oliver of Dielmann Sotheby’s International Realty is 20 Upper Warson Road, also known as the Westbury Estate.

Drawing from the legacy properties of iconic American and European families, the Westbury Estate was inspired by classic Georgian design and features timeless English architecture. “Decades from now, there is nothing about it that will seem outdated or was trendy at the time,” Alex Thornhill confirms. “The property will be just as classic and beautiful as it is today.”

The Westbury Estate was a labor of love by the owners and designers, with more than five years of research involved in finding the expert artisans and craftsmen. The owners took inspiration from the Westbury House and Gardens in upstate New York – the Gardens themselves taking inspiration from Charles II style – and has been reinterpreted for modern living and entertaining.


“The quality is unparalleled,” Thornhill adds. “These owners are probably the most attentive to detail I have ever met.” She explains that the estate was constructed using the best of the best: Minton Homes, Architect Pat Nolan, L’Atelier Custom Woodworking and Leonard Masonry replicating the limestone exterior carvings from the original Westbury House. “It’s all in the details with this house,” she adds. “The craftsmanship is meant to withstand the test of time.”

Thornhill sites the Parish glass conservatory at the back of the estate as an example. “It’s truly a work of art. The company dates back to the Victorian era, and was handcrafted in England. Each piece was labeled, disassembled and shipped to the United States. The English Parish contractor flew out on-site and reassembled it here.” It’s that dedication to every element of the estate that Thornhill says makes the Westbury Estate stand out.


For interior design, the owners turned to Carter Noel Miller. Having worked in the business for more than 30 years, Noel Miller was no stranger to designing for stately and elegant spaces. “I was referred to [the owners] by several past clients, and it was a very big and interesting project.”

After the owners visited the Westbury House in New York for research, Noel Miller derived inspiration from the Georgian revival aesthetic found in grand country manor homes. “I really enjoyed combining the more formal areas of the house so that it would flow with the more casual ones to create a warm family atmosphere,” Noel Miller describes. “From the dramatic front hall entry to the cozy family rooms, garden room and pool house, there is certainly a room for every occasion.”

This estate boasts more than 20,000 square feet, with six bedrooms and nine baths. Thornhill details amenities that homeowners won’t find anywhere else: “The pool and pool house, the tennis court, the putting green, the large health and fitness space with a gym, a massage room, an aromatherapy sauna and a juice bar, the six-car garage – these are rare finds in the St. Louis market, particularly all in one home.”

Thornhill and Oliver are giving this elegant estate the presentation it deserves, allowing every detail to shine when prospective buyers start looking. Pat Nolan meticulously designed every inch of the home, incorporating significant multi-piece Dentil, Egg and Dart, and Ogee moldings, inlaid wall panels, relief ceiling medallions, and four-sided Ionic capitals. The Georgian style calls for a bi-symmetrical design which gives the home an incredible sense of balance throughout. Even the orientation of the structure on the property was carefully considered to create a thoughtful approach to give residents and visitors time to absorb the home upon arrival, while aligning the home among the gardens, landscaping and outdoor activity centers.

Although the home took its inspiration from a classic Georgian estate, Thornhill encourages buyers to look at the Westbury Estate as a legacy property in and of itself. The classicism in the design and the quality of the craftsmanship ensure that this is a home that will stand the test of time.
