Workshop 150 square feet with loft

Posting has been infrequent as I complete my saw shack, a 150 SF workshop with a loft, the largest allowed without a building permit in my county.  It's on a low crawl space 10 feet 8 in. by 14 feet, with 2x8 treated SYP joists on 16 in. centers and 3/4 in. plywood subfloor.  Walls are balloon framed with 10-foot 2x6s on 2-ft centers.  The loft has 2x8 joists on 24 in. centers at a height of 7 ft., supported by 1x4 ribbons.  Loft access is by half an old stepladder located on the end with the door, and the other end of the loft is a vaulted area 3 ft. 6 in. wide. 

Rafters are furred down with 2x6s, allowing for layers of R-19 plus R-13 fiberglass in the ceiling, and walls are R-19.  The OSB wall sheathing is glued at all edges, making a very tight shell and hopefully draft-free and comfortable working conditions without heat.  Siding is Hardieplank with S-W Duration paint, and it took a while to complete; if I had used vinyl I'd be sharpening saws by now.

The new lightweight drywall was fantastic.  I've put up the old stuff alone with a lift, and this was almost one-handed, but then there was 230 linear feet of taping.  Doing drywall returns turned out to be more trouble for me than wood jamb extensions and casings would have been, but they make the interior seem larger.  Interior painting is about done and I am trying to get the vinyl flooring down this weekend.  I have already started moving saws into it.  If you tried to buy a Disston No. 12 for under $50 on eBay in the past year and lost, this is is where it is; sorry about that.

Power is 2 20-amp receptacle circuits and a 15 amp for lights; the workench receptacles are just 2 feet apart.  Lights will be 4-ft. strip fluorescents, and I also have a bunch of machine lights and 2 Dazor articulated fluorescent lamps.  My extra Foley equipment will have to stay in the old 1-car garage, and I will have 2 filers, a retoother, and power setter set up here.  I found a 54 pound steel cube at an estate sale which will be a ideal saw anvil.

Recycled materials include heavy duty outlets and bed molding between the exposed joists from Habitat ReStores, the R-19 from my crawl space (replaced with R-24 back when it was available), and window stools made from an unused yellow pine 1x6 in my house's attic.

Windows are vinyl with integral J-channels, modified with a ripped cellular vinyl strip spot-glued with clear PVC cement in the top channel and vinyl drip cap spot-glued to both and aluminum drip cap over all.  This prevents water from draining behind the siding in the J-channel.

While no building inspector has seen the shop, it passed both the earthquake and hurricane tests.  The week of the quake, I was off work to complete the insulation, and was on the 8-ft. stepladder where you see it in the photo.  Although the epicenter is only about 30 miles away, there was no foundation damage that I've found.
