Housing

i figure best way to keep land for organizations and activity’s would be to setting up a NPO (non profit organization) to pay the land taxes yearly. maybe make a open camp site or something. might even be able to buy a country that way.

trailers these days 76′ trailer can be purchased for under 20,000 dollars for a peaked roof, 10k for septic system, 10k to subdivide land and get an entrance made to your lot, 8k for power pole and hookup.

new windows double pain are essential in canada otherwise you’ll be heating way more than you need. pretty easy to frame in any size window with 2×4’s and drywall overtop of it.

replacing soft spots in the floor cut old floor out and put in 2×4 braces all the way around and put new peice of floor onto it.

moving the used trailer will typically cost 3-5k if its within hour drive.

things to check are black mold around window areas, soft spots around toilette, intact bellybag, and hitch to move it with usually tucked under the front.

some companies have assembly line where they make 6 mobile homes each day.

another good option is just a small 16 x 16 foot shack for 10k dollars in materials. the hardest part is flipping the floor over we were able to do it with a tractor but the back wheels were coming off the ground a bit.

Septic Systems

i’ve herd good things about the sunmar toilette if you don’t want to get a septic tank and just run grey water out the back. also have herd of people making septic systems from things like 45 gal drums tied together. you can pour your own and get it inspected or sometimes buying used one + bung can be a cheeper option

use one of these and pressure washer for unplugging septic systems

Insulation

non moving air is the best insulation you can get for building materials.

hemp plastic with air cavities like coffee crisp could replace polystyrene in some applications.

aerogel still expensive but is space quality stuff.

 

insulated siding.

Roofing

tin roof is probably best and sounds good in the rain, i’ve seen people just screw right into the old shingles to seal the holes, lapping can be used aswell if you want to put a gap between the shingles and roof for better moisture dissipation.

heating

rocket stoves

solar hotair / hotwater

campers addon/integration can be a great way to have extra room + facility’s needed. be sure to make everything airtight. fireproof cotten or straw + adobe walls might have enough insulation. if you put these on skids as living dwellings it would be in the mobile home tax / insurance range.
