I was hoping to get some input on this.
We just purchased some land in BC, and planning building site for the future.
This home isn't being built right now, but here is what were planning anyways.
What we were thinking, is a quonset home, not round, but where the sides are angled about 20 degrees, and the roof is about 40 degrees.
From what I've been told, this is the only style of metal building that can handle the snowload and have an importance factor of "1".
Or in other words, the rating of a home residence.
Where were building, there is no zoning. So aesthetics don't matter.
I actually think it will be a neat home, with lots of windows in the front facing the lake.
Maybe a 50x120 building, with a divider so the rear portion can be a large garage and shop.
We are planning to spray foam the entire metal building, installing wood stringers on the inside just strong enough to hold wall covering.
That seems to be the simplest most reliable method to go about this building type.
My main question, is the foundation.
The metal structure would be forcing outward, as the weight of the metal and snowload would force the walls outward.
So it seems to me like pilings are not a good idea, not only would they possibly shift outwards, but the building needs to be fastened along it's length, not just pilings.
To make it work, the pilings would need a footing poured across the top of them, also would need some type of tension cables from side to side,
to counteract the forces of the walls pushing the pilings outward. Seems elaborate and expensive.
I am really thinking the best way, might be a pad foundation. The pad foundation would provide the strength needed, and the mounting capability.
I have been reading, and I can find some information about pad foundations for homes, but it seems to be rare, so hard to learn much.
Ground contact foam seems to be key, to disrupt the freeze line under the ground under the pad.
A pad foundation seems like it would be ideal for this home, it could be poured over foam boards, and run in floor heating tubes when pouring it.
So wondering if anyone has any ideas or thoughts to say about this.
I have worked in construction when I was younger, I remember building a heated garage with in floor heating, the floor was 4" thick, but the edges went up to 6" thick
to support the wall weight. I'm basically thinking of the same design, but up-size the dimensions to accomodate the weight.
The goal is to have a long lasting home, little to no maintenance, and simplicity in design and construction.
With the metal building and closed cell spray foam, we should really never have to worry about things like moisture barrier or insulation installation quality.
With the pad above grade, and foam under it, along with plastic moisture barrier, we should never have any humidity coming in.
The pad brings up a different set of problems, like either elevating showers and toilets and running plumbing over the pad, or building a sub-floor.
Thoughts?
