A tiny bit about me..
I'm a decently skilled builder with a low budget. While 20k isn't NOTHING, its not even scratching the cost of a modern home. 20k likely doesn't even cover a permit, let alone everything else.
But I've done a lot of construction in the past and am probably adept as a builder. But mostly with modern/ "to the code" homes.
My big question is how long would people expect a simple offgrid house with these key parts would end up costing in time? If you ballparked hours of manual labor from start to finish, how many hours would you guess this below project would take upon starting?
Any and all your knowledge or info provided would be amazing! I have searched - but suggestions help me fill in the places I've missed in my own search and discovery.
Key house points:
-Post and beam, in the style of old barns but wrapped in plywood/paneling and insulated for home living space.
-Low roof, low slope roof, live grass/flower roof.
-One level, cement/earth/cobblestone flooring, no basement. (House will be on the top of a hill, low drainage in the area or on this spot. But likely I need to tamp down a hefty amount of gravel with some French drains just in case?)
-One doorway.
-Insulating walls after wrapped in plywood/paneling.. Wofati is interesting to continue a live roof with earth burmed walls for the insulative factor.. but I don't know a ton about it - would I still require insulation on the inside?
Luxury:
-Windows are a luxury that I'll invest in after the key points are finished.
-Internal paneling after installing insulation is a luxury ascetics item.
-Internal furniture.
Key questions if people have links or advice:
1. Anything and everything anyone can provide to me about living roof construction/materials/whatever. I've bought the 50$ underground house from Mike O and everything else he has available and many other materials besides his. Lots of discussions about Polyurethane or Pond liners for the sealing layers. I can't think of something better then a pond liner though.. if its designed to hold tons of water from draining away, it could likely keep water off the roof too. But I'd love anything else anyone can provide or give me insight on! Please and thank you.
2. Flooring, as it'll likely be a mixture of cement and stonework. While we're on the top of a hillside in the mountains I'm not too worried about water and drainage. A healthy layer of tamped gravel then concrete. But its never too early to ponder drainage ideas.. water is deceptively destructive if you don't respect drainage. Would I want to also use pool liner below the gravel to reduce ground moisture from working its way up?
3. Internal insulation for walls/roof after wrapping and the space is enclosed. After the live roof is installed properly, do I insulate it again from the inside? From many videos and documents I've seen it does not look like I would. But its worth an ask here! As for the walls I know unless I did a wofati style with earth burmed on the outside walls I'd likely need insulation.. or both?
