The Strands could potentially hold about 80 houseboats, a neighborhood of floating abodes at Port City Marina. A one-bedroom model home (above), staged by Ethan Allen, is already open for tours. A second house, a two-bedroom, is under construction, and both versions are beginning to be sold, said Dan Rambadt, director of business development/sales for Atlantic Houseboats. He said the plan is for the houses to take up two docks, with pocket parks at the end of each on the Cape Fear River side. The one-bedroom homes are 616 square feet and start at $279,900, and the two-bedroom models are 1,102 square feet and start at $319,900.
