1516 Castle Street is a custom shipping container residence designed by acclaimed local architect Rob Romero -- one of the only homes of its kind in the Wilmington market. The exterior is immediately striking: dark corrugated container steel, architectural board and batten, oversized black-framed glass, and a horizontal slat fence that creates a private urban enclosure without feeling closed in. Inside, heated polished concrete floors run throughout the main level. The kitchen is built around dark custom countertops, full subway tile to the ceiling, a matte black farmhouse sink, stainless appliances, and a bold rolling island with bar seating. The living area is anchored by a deep forest green accent wall and flooded with natural light through floor-to-ceiling glass that opens directly to the yard. The upper level holds the primary suite, which opens onto a private rooftop balcony. Adjacent is a custom flex room with warm wood open shelving and a pegboard feature wall -- ideal as a studio, office, or dressing room -- flowing into the full bath with a glass-enclosed shower, encaustic tile floors, dark charcoal vanity, and matte black fixtures throughout. The ground floor suite operates independently with its own private entrance and half bath. It functions cleanly as a home office, guest quarters, or short-term rental. UMX zoning permits all of it -- professional office and live/work use included. The yard is gravel with concrete step pavers and requires essentially no maintenance. No HOA. The Castle Street antique district is a short walk and the Cape Fear riverfront is minutes away. The property sits in the center of the Cargo District, one of the more creatively active and entrepreneurial neighborhoods in Wilmington right now. For the right buyer this works as a primary residence, a creative live/work space, an investment property, or some combination of all three.
