How do you propose to get large items upstairs?
I am adding a trap door on the opposite end of the stairs. I will build some sort of ladder lift or maybe just use my compressor room as a means of getting larger items up there.

I am in the process of trying to get quotes for insulation, I have been told that I need to insulate between the garage space and the second floor for 'code.' I do not believe that this is true, but is it a good idea to insulate between the lower space and upper floor?
don't know that I would bother with getting quotes for insulation. could probably knock yours out in a weekend by buying it straight from Lowes, where you also get bulk discounts
A weekend?!?! I think I would need a little bit of help to accomplish that. You volunteering?
however, you should probably accomplish electrical before you insulate
Yeah, truth. I need to get it all wrapped up, signed off, then I can pull another permit to do the additional electrical work. Hopefully we will be up and running by.........March/April/May?
I don't know when.....I think my contractor believes the government shutdown includes him......

Yeah, upstairs will be completely insulated. It will have it's own dedicated mini-split (or at least it's own blower unit).I am in total agreement with that-guy, I don't think that is a code thing either.
Anyway, if it were me and you want to keep either floor somewhat temperature controlled, I would insulate it. but you would still have to do something about the opening at the top of the stairs to keep cold from coming down or heat going up. YMMV
Are you totally insulating the upstairs?

It seems like every time my mud starts to dry out, we get some more rain......

Thanks!Nice build! Thanks for bringing us along for the ride.
Wish I could answer a few of the questions you've had, but unfortunately I have no clue what the answers are[emoji38]_hitti
I like your spiral staircase solution with the mini set of stairs at the top [emoji106]
My vote (for what it's worth) would be to fully close off the upstairs with a door of some kind. This will keep bad smells (car exhaust), sawdust, metal dust, or whatever else you happen to generate downstairs from migrating upstairs and making a mess
BLUE, yes, to keep the heat from the garage from escaping into the attic. the GREEN is a must. the ORANGE you can take or leave, but if you want the extra comfort, i say go for it
Yep. Reason being: Let's say it's the dead of summer. It's been a week of 85+ temps. Your HVAC and insulation have been doing a great job keeping the garage space and upstairs nice and comfortable. I'm assuming you'll have two separate thermostats (or 3 if your unit has 3 zones). You need to open up the one of the overheads to move some stuff in and out... No sense in the upstairs getting uncomfortable just because the doors were opened downstairs, right? The insulation will keep the two areas more or less separated as far as temperature is concerned. Yeah, the downstairs being conditioned will make much less work for the unit to take care of the upstairs, but the insulation will keep things from having to work that much harder.Even if the lower level is conditioned?

Thanks, Rocketman!To expand on this reply: I would take the green the full length of the trusses. This will keep the storage space between the trusses and the walls of the upstairs room from freezing cold or blistering heat, even without HVAC feeding them treated air. I would also do the orange areas....

I would insulate the whole attic floor. If money is an issue, insulate under the attic flooring first and add it to the open side bays later. In the summer most of the heat transfer into the attic is radiant and it will heat that space quite well. You could probably just put up the foil bubble wrap stuff to cut down on the radiant transfer. If you have one of those IR thermometers from Harbor Freight, you can see the difference pretty dramatically. Insulated ceiling on an 85-degree day will be close to 85-degrees but the un-insulated can be over 100-degrees. The load on your spit unit goes up dramatically in those conditions. I'm no expert, just a hack who tries different stuff until I get something to work. A 12,000 btu window unit keeps my 700 square foot garage at 78-degrees all summer long without breaking the bank (less than $250 a month for all-electric 2,600 square foot house in South Florida).Not sure about the attic floors yet. Like you I plan to condition the lower space, at least in the winter time (have PEX in my slab for heating). So if some heat flows up into the attic room, big deal? The insane mass of the concrete slab also does a good job at preventing the whole building from ever getting too hot in a Michigan summer, but I might run a mini-split downstairs as well, to hold 80°F and control humidity in the summer time. In this scenario, why have insulation between downstairs and upstairs? Same temp setting, basically. If I have leftover R13 or poly iso sheets, why not put them under the floor I guess. But not worth spending another thousand bucks on, IMO.
I have not checked in for a while so I just reread the whole thread over lunchdamn nice build! A couple thoughts... your home built scaffold- that deck is being supported by the fasteners that secure it to the posts, and I dont see any lag bolts or ?? - with one or two guys and tools and materials up there, it is going to be a LOT safer if you add "jack studs" to each of those corner posts under that deck to carry the load down to the base... or at least use some overpriced Simpson metallic connection
I was looking at that pony wall at the top of the stairs and thinking that with a door at the top of the stairs I would do a simple frame to match whatever you trim the room with and use glass or acrylic to close in from the top of the pony wall to the ceiling.
