While we have enjoyed our basement here, I think every basement on the planet has some problem or another. It doesn't need to have problems , ventilation and a good perimeter drain system can insure a dry useable basement . So, we want to go pier a beam. Besides the avoiding basement issues, pier and beam is cheaper ... and you don't have to tear up the land to do it. But I have some questions. Post and pier means a crawl space , so not a basement , but still a space that needs insulated and ventilation. Best Insulation -- While R30 is available in bats, I have seen too many pictures of fiberglass hanging out from under floors to be impressed. Closed cell seams like the way to go -- if you have a treasure chest of gold to dig up and spend. Suggestions? Again , installed properly batts no not have to hang down or be unsightly. I Ohio yu might go with a flash and batt system , a few inches of spray foam with batts applied after the foam is cured. Am I Nutz? -- Most of the buildings on this site promote pier and beam -- many in cold climates. But I will soon be celebrating 30 years of marriage -- and would like to have a few more. If my wife puts her feet on a cold floor too many times, I will be outside in the dog house. Do pier and beams mean cold feet?Most of the building here are considered cabins , BUT even if you go post and beam you'll still have floor joist bays to insulate. I think your confusing pier and beam with a car decking / no floor joist floor system . Moisture Problems -- With a little bit of trellis to keep out the skunks and raccoons, I am guessing a pier and beam is still open enough that it will not develop its own climate to create condensation in the summer. Is this true -- or does a pier and beam create the same issues as a crawl space. Yes sort of , you are still creating a under floor space , commonly called a crawl space , as to get around under the house you'll be crawling , not standing. So the space needs to be vented and enclosed to keep uninvited guest out. NE Ohio Soil -- I think this last question will really require specific information about the building site. But generally speaking, it seems that the footers do not have to be dug down to bedrock. I have read about cases in the south where piers are dug very deep to hit bedrock. When is digging to bedrock a necessity? When is a good footing enough? NE Ohio , you need to get what ever footings you under under the frost line , or you may be able to use a slab on grade foundation. Which becomes the sub floor on the ground level. It would need to comply with codes in the local area , be thicked at the edges , and at any bearing points . So it's a different way to build off of than you've been talking about.
I am not confusing this with anything. I am referring to the type of foundation discussed on this site: http://countryplans.com/foundation/index.htmlWhen I am referring to a crawl space, I am referring to a continuous vented or unvented wall like this:The "best practices" for crawl spaces these days indicate these need to be completely encapsulated and dehumidified (aka conditioned). I want to avoid that -- depending on the answers I get.Slabs have an advantage of thermal mass. But they are extremely expensive to fix if they fracture. However, a pier & beam or crawlspace are easy and cheap to fix should as they settle.My questions were related to foundations that look like this:
While extra bracing sure doesn't hurt anything, under a certain height (as well as local wind loads), it isn't required. And the compressive strength of a 4x4 post is pretty substantial, but I would bet those 4x4s are placed closer together than your 6x6s, to make up for the smaller size.The houses in the pics are probably built to code...
Assuming the side window on the house on the right is 3' wide and using it as a visual aid to determine the spacing of the posts,
I would not be happy about their unbraced stability unless they were no higher than about 6".
The houses in the pics are probably built to code...
I wish the OP would tell us where these pics come from because these houses look really familiar...
Arky:If I had a blue ribbon to give you, I would. That is the nicest pier and beam foundation I have ever seen. Some fine looking wood and thoughtful construction. I could see elephants dancing on that foundation without a problem.Are you planning to add a skirt? If so, how are you thinking of constructing it?BHH
Erin:These came right off of www.countryplans.com. (http://www.countryplans.com/leblanc.html)BHH
Arky:We're planning on building a shotgun house as well. While we live in Ohio, we are originally from Georgia.A shotgun house has a southern appeal.BHH
