House Support

[kermit911]

If I was to build a house 88 feet x 54 feet with a full size basment. Would there be away to support the house without having support beams going down the middel of the house? I would like to put a small theater in the basement, but the support beams would mess up the atmosphere. Here is the site with the house I want and all the info on it, http://details.coolhouseplans.com/details.html ?pid=chp-30174&FoundID=64&sid=chp23

Thanx

You need to pay a structural engineer for a proper answer.

For a non-proper answer (ie; don't go and try 'cos I said!) it might be possible, but unlikely (and expensive). You'll need to use some very deep steel beams running transversely across the house. Even then, it's possible that you won't be able to get them stiff enough within the space available, so the upper floors will sag towards the centre of the house under the weight of the furnishings and interior fit out.

Thanx, so it is posible? Just expensive.

I cannot see a basement on your link. Where would it be and what is the plan size?

[kermit911]

That site should give you the demensions but it dosn't show the basment. THe basment is an option that I can get with it. Thanx for the help

So the basement will be the same length and width as the house roughly? And is it to be a timber framed and timber clad house?

[kermit911]

that is correct

Am I right in thinking that your 54 feet in your opening post is wrong and that it should be 24 feet ?

you need a structural engineer to do the business. really you do!! I'm doing civil engineering and common sense says to me that you're going to need columns or a wall running at least down the middle to cut the span in half if not into three. as well as this you would have to use some big steel i beams instead of some pretty timber. you won't get a bit of timber much bigger than 6m long at best thats 18ft.

as in the first post imagine the sag of the wall above.

please pleas get a structural engineer in.
