Perfectly located in the heart of Gibson Island, this exquisite American Craftsman residence offers timeless architectural character and tranquil views overlooking Otter Pond. A stone walkway winds through mature landscaping to a striking covered entry, where a handcrafted wood front door, lantern-style gas lit sconces, and exposed wood eaves introduce the home’s thoughtful design and refined craftsmanship. Originally built in 1930, this property was comprehensively rebuilt and expanded in 2023 by the current owners. Designed by architect Bryian Swanson, Swanson Design, and constructed by acclaimed builder Delbert Adams, the home blends classic, high-quality Craftsman elements—textured stucco, copper gutters, architectural shingles, deep overhangs with natural wood detailing, custom mahogany vaulted ceilings and front hall cabinetry, and custom Andersen windows—with modern enhancements. Throughout the home, tranquil pond and woodland vistas reinforce a sense of privacy and connection to nature. Both welcoming and secluded, the setting captures the essence of Gibson Island living--architectural integrity, natural beauty, and year-round appeal. With an interior footprint of 6,348 square feet above grade and a 1,150-square-foot finished basement, the floor plan includes six bedrooms, five full baths, and two half baths across three finished levels. A chef’s gourmet kitchen designed by renowned kitchen designer, Jennifer Gilmore, is at the heart of the home. The house includes a breakfast room, living room, “pond room, ” den, and stunning wet bar. The private, wooded property spans 1.1 acres, is thoughtfully landscaped and has an irrigation system for the upper lawn and garden areas. The property conveys with a separate 3,225-square-foot waterfront lot off Stillwater Road below the house, ensuring permanent views and direct access to Otter Pond. If a dock is to be built there, it must be approved by the Gibson Island Corporation Architectural Committee, the Gibson Island Corporation, and Anne Arundel County, and other governmental entities. More information on this may take additional time. The grounds are thoughtfully landscaped. Information on Gibson Island: Gibson Island is a private island within one hour of Washington, D. C. and Baltimore offering an absolutely extraordinary setting. The Island comprises 1000 acres with seven miles of shoreline. Two thirds of the Island is undeveloped and is owned by the Gibson Island Corporation, the homeowners' association. The remaining third is residential home sites. Gibson Island is located on the western shore of Maryland, so there is no need to cross the Bay Bridge. On the Island is a 43-acre spring fed freshwater lake in which one may enjoy non-motorized watercraft activities such as paddleboarding, canoeing, kayaking, fishing and swimming. The Island offers enormous privacy and security--there is an entry gatehouse staffed 24+Hours, and the Island is patrolled by the Gibson Island Police Force (GIPD). The Gibson Island Corporation Service Department offers yard maintenance and landscaping and other services for homeowners. There is a full-service yacht yard. From the Island, it is just a 20-minute drive to BWI Airport and the neighboring Amtrak train station. The Island houses a private country club (membership by invitation) offering yachting, fine dining year-round, tennis, an award-winning Charles Blair Macdonald designed 9-hole golf course, swimming, croquet, skeet shooting, and more.
