I like your storage-below idea. I assume you're going to put drawers/file cabinets and that sort of thing down there. It's not going to be a very accessible space for other stuff because you'll end up with about 4' of height below your platform. Personally I'd keep 7' of head room, because 6.5 would make me feel claustrophobic.
Maybe you should wrap the workspace in one-way glass, so you can look down on the room like some sort of manager. :p
ok... ... so assume I do a short wall on the ends using 2xX studs and I
span this with 2xY's on Z" centers and I want to support W pounds...
what should X, Y and Z be to support W? If W is 3K pounds... what
are X, Y and Z? Is there an easy ( cheap ) way to get this answer?
How do I come up with a good guess for W?
I'm just worried ( I've never looked at doing anything like this before )
that the ends / short walls will have too much load on them and put too
much downward force on the concrete slab. The reason I said use the
cinder block wall along the back was just to spread the load....
Lastly... if I use two short walls on the ends with the floor joist spanning
them... I can always ( slowly ) jack up the floor and adjust the height of
the side walls. Try it out with a 6' walk space up top for a few weeks and
lower it 6" if it's too claustrophobic... The more space up top... the less
space down below... this assumes that I can just use some short walls
on the side to support this structure.
Here is a thread
High Ceiling utilization
that I can use to talk about the interior design aspect of this if anyone
