Hello,

If youare building a 14 x 14 platform can you use 2 x 4's for the
joists, if the platform is sitting on a floor, and still put kitchen
appliances on it? Would putting the joists closer than 1 ft. help? The
floor boards may be 1 x 4?

Thank you.

If you're gonna use 2x4's as joists, then you'll need to make sure they
are either:

a. sitting flat on an existing floor or
b. supported (suppose you have to level it or something) every 2 feet or
so. i have done just this myself to make a level spot for a washer and
dryer in a kitchen owlcove, and used tapered door shims every foot or so
to support it. then i poured wood glue over each spot to make sure they
didn't work out from under there.
