I think we've finally found someone who can do our house, and come in under budget. It'll be a 12x24, which is smaller than we had planned, but we'll work it out. So, the question is about how many piers to put in. I haven't checked with the code guy (and will, obviously) but the builder told me they need to back their trailer up between the piers to drop the house on it, so we can't have any down the middle of the house. he seemed to think that four down each side would be plenty for a house that size. What do you all think? By the one pier per 50 square feet rule, that's more than enough. But the lack of central support concerns me. Will beams really be strong enough without some sort of support in the middle of the floor? This is, of course, a single floor home. We will have a wood stove, but it'll be a small one.

Hopeful, do you know what the floor joists are made out of (2x10,2x8, 16" on center, etc ?)

No idea. he might have told me, but I don't remember. He does know that this needs to be up to code for a house, and has built houses before, so I assume he'll put in whatever will be required by code. Tomorrow I'm faxing the sheet that the code guy sent us to be filled out, so I'll have all the details when it comes back.

Just to throw a couple thoughts in. You will definately have to coordinate the exact spacing of the piers with the builder....example, if the outside skids of the structure will be 11' on center then the piers will need to be the same so the outside skids ride exactly on the piers...another thought is are the joists pressure treated? if not then the piers will have to be in the 14" to 18" above grade range plus the height of the skids, as untreated lumber will need to be at least 18" above the ground so they don't rot. Treated lumber you would be ok below that, but I would want that height anyhow, you might want to get under there at times. Another thought is, you should have center skids on the structure as they will be needed to load it on the trailer, you could have them hand block the center with cement blocks as part of delivery, as you will have the height where they can do that easily. The blocking won't be in the ground but should add good stability.

I really wish we had help with this. I'm so afraid we're going to mess something up.

just a thought. You could use deck blocks and get the Amish to build you one. I have a price list from them and they will build you 15x10 for 1500.00. It has a steel roof and built out of rough sawn pine. This will allow you to do all the finish work and buy everything else on Craigslist.You can negotiate with them and they would probably set the doors and windows for the same price. Just a thought keeping your budget in check. Is this a weekender or a residence?I guess that would make a difference
