A pair of Billy Cotton–designed residences on the Upper East Side

AD100 designer Billy Cotton has created homes for renowned artists Cindy Sherman and Lisa Yuskavage, as well as performers David Harbour and Lily Allen—and he’s spent time as the creative director at Ralph Lauren Home. Now, the designer has unveiled two luminous model units in the The Treadwell, a new condominium on the Upper East Side.

Both homes are furnished with a mix of custom pieces and vintage finds sourced at the Paris Flea Market, creating a sophisticated lived-in quality in the spaces. Distinct textures and custom millwork combine for a truly sumptuous atmosphere that offers a tranquil antidote to the hustle of the city.

“The vision for these homes was to create spaces that are natural, simple and elegant,” Cotton said in a statement. “I wanted to create a design that felt sophisticated and welcoming, while paying homage to our setting in the Upper East Side.”

The two-bedroom, two-bathroom unit, 18C, will be available for $2,905,000, while the three-bedroom, three-bathroom 19B’s list price is $4,075,000.
