JAW,
firstly, binaries should be posted to alt.binaries.pictures.woodworking or alt.binaries.pictures.furniture with a reference here in the wreck (rec.woodworking). Most won't see your post as ISPs will discard it in a text group.
To answer your questions:
Put the BS on wheels and stick it in a corner until needed.
a. I can't see natural lighting or ventilation in your finish room. b. You may want to rethink the size of the entry door and make it bigger; looking at the bench and saw - they won't fit in. Also taking out large projects is a pain. c. Try to have the door where long pieces can be fed through the door to the TS. d. I can't see where the dust collector is, you may want to think about installing one. e. pendant outlets over the bench are great, they keep cables off the floor.
A raised floor is great if you can afford it, otherwise dropped from the ceiling is fine.
I'm sure others will "chip-in" with their comments.
g'luck
Greg
