20 Lighthouse Way, Darien, Connecticut 06820

About this home

Welcome to 20 Lighthouse Way, where coming home means stepping straight into a waterfront lifestyle. With a private boat mooring and the Long Island Sound at your doorstep, the transition from the workday to the water is effortless. Launch a paddleboard for a sunset outing, hop in a kayak, take the boat out for a spontaneous cruise, or enjoy waterskiing-all from your own backyard. Here, the best part of the day may be what happens after you get home. The heart of the home is a newly renovated, crisp white kitchen that flows effortlessly into a sun-drenched dining area and spacious family room centered around a cozy fireplace. Whether hosting a summer soiree or enjoying a quiet morning coffee, the open floor plan feels airy and intuitive. For those who need space to spread out, the first floor is versatile, featuring a bright living room with fireplace, dedicated office, oversized playroom, and functional mudroom with ample storage to keep coastal life organized. Upstairs, the primary suite and a second bedroom offer breathtaking water views, serving as private sanctuaries to watch the sun sparkle on the water. With four bedrooms and three updated baths, there is ample space, plus the flexibility to easily convert back to a five-bedroom layout. Outdoor living is elevated here-literally. Expansive decks on both levels overlook the water, providing the ultimate backdrop for alfresco dining and family gatherings.

From the Darien assessor's public property record. These figures describe the property as the town has it on file and can differ from the listing — a finished basement or an addition may not be reflected in the assessor's living area.

Recorded sales

Deed transfers on file with the Darien land records, newest first. These are recordings rather than MLS sales, so they include transfers that were never listed. Nominal and $0 transfers (estate, trust and family conveyances) are excluded.
