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 if the house is old enough, it was probably built before there were rules.
How about 100 feet of lakefront on 90% of an acre for $139,000? There's a 1 bedroom 1 bath, oops, just a 1 bedroom, 330 square foot tiny cabin that hugs Long Lake. How minimal do you want to be? Here's a fine exercise in building up from the most basic of basics; but with a lot of lot, and a lot of possibility.
At some point, extreme minimalism leaves many behind. Maybe that's the case here, but every house is only going to have one final buyer. They say one bed, and it looks like one mattress. The kitchen is a range and a table and chairs, and nothing else. Anything like a bathroom needs water coming in and a place for whatever is flushed out. The closest this property gets are designs on file for the well and for the septic.
Everything is solvable. Surely there's one person who knows how to make this work.
Maybe this solves Tinies' biggest problem: finding a place to live. The ones built on wheels are meant to move, or at least to maneuver around zoning and building codes. The cabin on the property may be too rustic for some, but a new tiny on an existing lot that has designs for septic and well, (oops, evidently the water isn't in yet, either) may just find a site either in place of the old building or somewhere else on the 0.9 acres.
This cabin was built in 1964, probably for the simple idea of getting away from the city and peacefully enjoying a lake. Thanks to the ferry, the commute is only about an hour to downtown Seattle, theoretically. Most hour long commutes leave you in places that cost more and have more restrictions. Lots of pieces are in place here. They just take a bit of work, and money of course. After which you've got a quiet place to live, fish, and relax.
