Sandcastle I is a mid-rise beachfront condominium completed in 1982 and rising 16 stories with roughly low-density occupancy (about 92 units). The collection of primarily one- and two-bedroom residences emphasizes coastal layouts with split bedroom plans, multiple primary-suite possibilities, and living areas that open onto expansive wraparound lanais or balconies with gulf and beach vistas. Interiors commonly feature tile or woodlike flooring, granite counters, updated kitchens with stainless appliances, in-unit laundry, high ceilings, custom closet cabinetry, and a mix of traditional and modern bath fixtures such as dual sinks, jetted tubs and separate showers. Building amenities reflect a full recreational profile: a large pool and heated spa, covered and assigned parking, a fitness room, social/community room with catering kitchen and bar, tennis and pickleball courts, outdoor grilling stations, storage and outdoor showers. Security measures include impact-resistant sliders/windows and storm shutters on many units. Elevator access serves public corridors; lower-floor condos provide easy stair access to the pool and beach. Onsite management, good reserve levels reported in listings, and rentable units for investment use round out the services. The location on Marco Island’s desirable south end places Sandcastle within short walking distance of restaurants, shops, a movie theater and island entertainment, offering a resort-like, beach-centered lifestyle with straightforward access to shorefront leisure.
