Location: Long Beach, California

Price: $9,950,000

In most developments, a corner lot means additional acreage and some breathing room from the neighbors, at the cost of privacy and an uptick in road noise. Well this corner lot in Long Beach, California, certainly has the extra space, but none of the auto interference. That's because the lot juts out into Alamitos Bay, affording direct waterfront on two sides. The seven-bedroom house at the center of this choice property takes the setting and the island's name -- Treasure Island -- to heart. The wood-paneled den is crafted to resemble the interior of a square-rigged ship of yore, where a giant aquarium makes up one wall. As usual with this sort of unique personalization, the present owners might not see a return on that dramatic renovation, even with the heady $9,950,000 price tag.
