Chilston Court Brings 78 Luxury Residences to Downtown Greenwich

KEY TAKEAWAYS: Chilston Court is a 78-residence development at 275 and 290 Mason Street in downtown Greenwich, with completion planned for 2028. The project is led by Caspi Development, a Westchester, Fairfield County, and New York City-based developer with more than six decades in the business, whose past work includes the five-star Fouquet's New York. Architecture comes from Robert A.M. Stern Architects, known for some of New York City's most prestigious residential buildings, while interiors are by Bryan O'Sullivan Studio, an AD100-recognized firm whose portfolio includes Claridge's in London and the Westmoreland at the Frick on Manhattan's Upper East Side. Residences will range from two-bedroom units to penthouses, priced from roughly $4.5 million to over $10 million, with two-bedroom homes measuring approximately 2,000 square feet.

The scale of the residences sets Chilston Court apart from much of what's come before it in Greenwich. Two-bedroom units running close to 2,000 square feet push well past typical downtown condominium proportions, and the design team has aimed for something closer to a backcountry estate feel in a walkable location near the Greenwich train station and the shops and restaurants along Greenwich Avenue.

Robert A.M. Stern Architects drew on Greenwich's own architectural history for the building design. Renderings show a brick-and-limestone facade with a central pedimented pavilion and arched, triple-height windows - a direct nod to the Georgian and Classical Revival buildings that define much of downtown Greenwich, reworked at a larger residential scale. Paul Whalen of RAMSA described the goal as reinforcing what already makes the town desirable to live in, while still raising the bar for what residential architecture in Greenwich can look like.

Inside, Bryan O'Sullivan Studio's design work is built around materials and craft. Renderings of a model kitchen show rift oak cabinetry with brass hardware, a waterfall marble island, and fully integrated appliance paneling. A model bathroom features book-matched marble flooring and a marble-clad shower and vanity. Living spaces are designed with ceilings exceeding nine feet and custom millwork throughout.

Public and amenity spaces follow the same material language at a larger scale. Renderings show a private dining room finished in saffron lacquer with a botanical mural and brass branch-form chandelier, seating close to twenty at a single table, and a speakeasy with a green-marble bar backed by brass shelving and a mirrored liquor display. A garden room features a sage-green ceiling, limestone flooring, and a wrought-iron chandelier, opening onto planted courtyard space. A separate clubroom, shown in walnut paneling with a pool table and gallery-hung art, adds a more informal social space to the building's program.

The full amenity list is intended to function like a five-star hotel rather than a typical residential building. Planned spaces include:

• An indoor pool and wellness spa
• A fitness center outfitted by Technogym, with a sauna, steam room, and treatment rooms
• A private dining room and speakeasy
• A residents' lounge and a separate library lounge
• Landscaped gardens with sculptures, fire pits, and water features
• A pet spa
