Condominiums at Chilston Court in downtown Greenwich are selling for as much as $12 million, shattering the town's previous condo price record and drawing interest from New York City buyers fleeing a new tax.

Developer Joshua Caspi said the 78-unit project at 275 and 290 Mason St. is approaching 50 percent sold, with more than a dozen units priced above $10 million. The previous Greenwich condo record stood at $6.7 million, paid for a unit at the Modern on Field Point.

"I didn't expect the strong response. We're getting close to selling almost half the project, nearing 50 percent," Caspi told Greenwich Time.

Demand for top-tier units outpaced expectations so sharply that Caspi raised prices repeatedly and pulled remaining high-end inventory to release later rather than let buyers bid each other up, according to the New York Post.

Most buyers so far are from Greenwich and nearby Westchester communities including Purchase, Rye and Scarsdale. Many are homeowners in their 60s looking to downsize from large homes. The Post reported Aug. 14 that about a quarter of buyers have or had places in New York City, and several have sold their city residences to make Greenwich their secondary home, partly in response to Mayor Zohran Mamdani's new pied-à-terre tax on high-value properties.

The project sits on the former Honda dealership site at Bruce Park Avenue off Greenwich Avenue. Designed by Robert A.M. Stern Architects with interiors by Bryan O'Sullivan Studio, the two buildings rise five and six stories and feature Indiana limestone bases and bricks imported from Holland. Units include 8-foot-tall windows, ceilings above nine feet and single-slab marble kitchens. Two-bedrooms start around $4.5 million; penthouses begin at $11.5 million.

Amenities include a 55-foot indoor pool, wellness spa, fitness center, private dining room, speakeasy, wine cave with individual lockers, library lounge, landscaped gardens and a pet spa.

"The amenities are much more robust than anything that's been created out in the suburbs," Caspi said.

The Greenwich Planning and Zoning Commission approved the project in late 2024 under Connecticut's 8-30g affordable housing statute, requiring 32 percent of units to be designated affordable. Superior Court Judge Claudia Baio upheld those conditions in early August 2026, dismissing a challenge from the developer. Developer spokesperson Michael Thomason said the project would proceed as planned with no impact on current buyers.

Caspi, 47, also serves on the Central Middle School Building Committee overseeing construction of Greenwich's new school. His past projects include Fouquet's New York hotel and the Chambers Hotel in Manhattan.

Chilston Court is expected to be completed by the end of 2028.
