About This Home
Update: Offers are due at 6pm on Monday June 15th. Set along one of Westport's most coveted stretches of the Saugatuck River, 18 River Lane is a timeless 1939 English Manor offering a rare blend of architectural character, waterfront serenity, and exceptional potential. Privately sited on 1.38 picturesque acres with sweeping river views and mature landscaping, this six-bedroom residence embodies the elegance and craftsmanship of a bygone era. Rich in period details, the home features graciously scaled rooms, distinctive architectural elements, and an inviting floor plan designed for both comfortable living and entertaining. The versatile layout includes a full walk-out lower-level apartment/studio, ideal for guests, extended family, a home office, creative workspace, or au pair accommodations. The spectacular riverfront setting provides a sense of tranquility and privacy while remaining just minutes from downtown Westport, the train, beaches, and top-rated schools. An extraordinary opportunity exists to further expand the estate, as the adjacent 1.13-acre building lot is also available for purchase, creating the potential for a remarkable compound or future development opportunity. A truly rare offering where historic charm, waterfront living, and limitless possibilities converge. Septic system is only 750 gallons. If making an offer, please indicate if you would like to also make an offer on the adjacent property, #20 (the tennis court property).
