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.
