We have bought a high school gym and we are making it our home. It has great bones. We are going to build a second floor and was thinking that it would be ok to use 2x8 floor joist instead of 2x12 floor joist, What do you think?
So you have a big open area that is most likely on a slab and you will be framing walls on top of this slab around 14'-14' 6" supporting a second floor. What do you intend to do about footings underneath these walls that will be supporting the second floor?We have bought a high school gym and we are making it our home. It has great bones.

We will be adding walls...
Span will be 14 ft to 14 1/2ft and it will have 2 bedrooms 3/4 bath and a sitting area.
And aren't those the load bearing walls set at.14' supporting the second floor? These are the walls I've been talking about. If so....where do they land on the 2x12's?wesshe69 said:Joe, Only the interior walls will be perpendicular to the joists.
You designing this yourself and drawing it up to bring to the building department for permits and inspections?wesshe69 said:Span will be 14 ft to 14 1/2ft and it will have 2 bedrooms 3/4 bath and a sitting area.
Where will your walls land on these 2x12's?wesshe69 said:Joe, yes this is a wide open space. The gym sits on concert footers that runs the length of the gym (80ft) and then it has 2x12 joist sits across them (36ft-width of gym), it has a subfloor that is TG, then has the wood floor TG on top of it.
Any walls perpendicular to the joists...if so where?wesshe69 said:Just measure and if it ends up in between the 2x12 then build additional floor joist and support underneath.
