Portsmouth, RI Mott & Chace Sotheby’s International Realty completed the sale of 230 Briarwood Ln., for $4.5 million. The sellers were represented by Joseph Costa and Kylie McCollough, both sales associates of Mott & Chace Sotheby’s International Realty. Benjamin Willett of Serhant Rhode Island represented the buyers.

According to data from the MLS, this is the highest sale in town since the sale of 483 Vanderbilt Ln. in December of 2024 in which McCollough also represented clients.

“Sea Farm”, an eight-acre estate designed by Estes Twombly Architects, blends modern style with classic New England charm. Views over gardens and conservation land flow directly into the indoor-outdoor living in which the home shines with a Solisysteme pergola, 2,000 s/f granite terrace, and a saltwater pool. A separate four-car garage with a studio apartment adds versatility for guests or creative work. 

A perfect balance between a touch of country living, luxury and traditional craftsmanship in a stunning natural setting.

“Bringing Sea Farm to market was an honor,” says Joseph Costa. “The home’s design, craftsmanship, and natural setting created an experience that captivated buyers instantly. It’s a rare property that perfectly balances modern luxury with timeless New England charm.”

 “Sea Farm offers the rare union of privacy, coastal elegance, and contemporary design, an architectural estate of exceptional caliber,” adds Kylie McCollough. “It was a privilege to represent this extraordinary property and, for the second consecutive year, achieve the highest sale in Portsmouth for my clients.
