Sea Dunes
Sea Dunes is an 8-story oceanfront condominium at 5400 N Ocean Drive on Singer Island in Palm Beach County, Florida, built in 1969 and comprising just 32 residences arranged four per floor.

This boutique association offers a heated oceanfront pool, a fitness room, a community/social room, a renovated lobby, owner storage, a guest suite, and direct private beach access, along with common laundry facilities and ample parking. In recent years the building has completed concrete restoration, wiring updates, roof work, and a new seawall, and it does not permit pets. Sea Dunes sits on the northern end of Singer Island, a low-density barrier-island community known for its quiet beaches and proximity to Peanut Island and the Palm Beach Inlet, offering easy access to snorkeling, boating, fishing, and paddleboarding just outside its doors.
