So building a basement of stone wide enough to hold cob, would be a huge time consuming effort?
It would take longer the building a room of cob?
I was gonna pour a few inches of pumice below the structure to insulate and in-between the stone and the earth, thought I had it all figured out. Where I live we have an abundance of stones, I thought i'd be putting local resources to good use.
The houses with basements around here tend to have warmer floors in the winter, they do however occasionally flood during spring thaw, when the snow melts quicker than the earth unfreezes, leading to unusual moment of surface water..which is why all of them have sump pumps. Also our frost line is at about 4' I would have to dig in 4.5' in any event to accommodate the drain, so why not just put a basement in if I have to dig that deep any way?
Could I leave berms of earth inside the basement, to reduce the work, where loads would be above so I don't have to put Stone Walls every where I'm going to have a load.. rocket stove and bench, large bath tub, and a middle supporting wall, (because the second floor is only half the size of the first floor)?
Jay- in your estimation how much longer would it take?
Basements in general, unless prefabbed and/or formed, are always gong to be more effort than a wood structure above grade. It is also a "skill set" related topic, as the more building skills (knowledge) one has, the easier it becomes. I would also suggest that if you build with stone the only cobb that would be needed would general be used for a traditional cobb mortar. If plastering is used that is consider a finish treatment and I would suggest lime over cob in that case. I don't like cobb in basements or below grade in most (not all) designs.
I love the idea of a house on boulders...but it is too cold here in the winter for that not to increase heating costs.
I want a cellar, a walk out cellar because I do not want to store hundreds of gallons of collected rain water in a cob room, and I prefer my laundry piles out of my living space, and I need a place for my batteries, and solar equipment. Seems that all that stuff is best put in a basement...
I have a (eek) plastic potable water tank designed for holding water tight! until my soldering gets better and I learn how to make or come across copper one,or win the lottery and buy one, its going to be the only plastic thing in the house. I hate plastic.
I have a box I had built to my specifications with vents medium low and a chimney vent with a vent fan up high and a very tight lid for my batteries.
I have a chain hoist and a lever bar, and I forget what they are called.... a rock hammer? For making thing fit, And an abundance of Rocks of every size, I look forward to the puzzle. I work with people all day and they puzzle me the most, I look forward to one I can hopefully solve.
...am I forgetting anything?
The frost line doesn't matter? I JUST NOW understand your saying I don't need a cellar...
I think stone and cob are so beautiful together. Do you think it is a misuse of resources? will I be disturbing nature too much by using them for my cellar instead of leaving them where they are?
Did I say I redid my design to be 15x20 on the inside.. I guess that 20x 25 on the outside..I was trying to make it sound small.
