Welcome to Tiny Homes, an idea that is more popular with minimalists than with neighborhood associations and zoning boards. We'll point out the fun parts. You'll have to check out the logistics and legalities - but this one's probably older than some of the ordinances.
Open a wall and add the great outdoors to what would otherwise be a tiny space. Someone took a 1940 beach cabin, made it new with doors instead of walls, upgrades to kitchen appliances, new siding, roof, and decking, added another deck beside the sea wall so you can lounge without having to look past any obstructions. They basically did so much work that you might not notice that it is a 336 square foot studio floor plan with only one extra room: the bathroom - and even it has a great view. They're asking $424,500 for a tiny house, but it is waterfront on Camano Island's Tyee Beach, an island property that can sound quite remote, but is only a drive away. No ferry required. The house is tiny but the lot is a sizable 15,000 square feet. At low tide, there's a lot more to play with. Depending on your preference, there's also the opportunity to catch fish, clams, and maybe crabs. It's already equipped with an essential beach appliance, an outdoor stainless steel sink for cleaning seafood so none of the mess or smells have to come inside.
