Rarely does a home combine views this dramatic with privacy this complete. Set on an oversized, beautifully landscaped homesite at the end of a quiet cul-de-sac, 70 Deerfield Road enjoys captivating marsh and Port Royal Sound views, with the newly renourished sands of Pine Island Beach at Dolphin Head visible from multiple rooms and accessible just steps away via the beach path. Comprehensively refreshed in 2025-2026, this custom residence offers effortless Lowcountry living with every bedroom featuring an ensuite bath, a separate dining room, and a richly wood-paneled den with pocket doors. The primary retreat occupies a private pod all its own; hidden behind a discreet door off the living room, it reveals what may be the most spectacular sunrise view from bed you will ever experience. Outdoor spaces include a private courtyard, screened patio, expansive deck, sunken hot tub, propane-fed grill station, and zero-step ramp access, while a large folding living-room door invites the outdoors in. The well-appointed kitchen features a spacious island with seating, dual ovens-one convection-a five-burner cooktop, generous pantry storage, and an adjacent wet bar. Significant improvements include crawlspace encapsulation, extensive spray-foam insulation, refreshed skylights, three geothermal HVAC systems, a metal roof, PSD water, and well-fed irrigation. With extraordinary privacy, exceptional indoor-outdoor living, beach access, and one of Hilton Head Plantation's most remarkable marsh-to-Sound settings, this is more than a beautiful home-it is a truly special retreat.
