I am soon to be a homeowner, and need some assistance from the IBB collective to help achieve success the first go around on some projects I have planned.

I am in the final stages of closing on a 5 acre parcel with a small house and two outbuildings. The house is a small one bed / one bath unit on a 24X36 slab. The house is liveable as it is, and will be fine for me and the dog. I am more concerned about getting the outbuildings up ready for use.

One is a 24 X 24 two car garage and one is a 15 X 24 shed. The garage has 15 amp service pulled from the house, but the shed has 100 amp service and a panel.

The garage needs some work (building on the left), but it is going to wait until next summer to get all titzed up. I am planning on starting the small shed next week (the one behind the truck)

I don't have any good pics, but here is what I was able to pull from the appraisal report:

This property used to operate a greenhouse, and the small shed I am starting on was where they grew the seedlings every spring. The humidity caused the drywall to mold/mildew and it has a pretty nasty smell going on. Since I don't need to do electrical in there, I figured it would be a good spot to start.

My current plan is to pull all the drywall and insulation, re-insulate and put up steel siding with a corrugated galvanized steel ceiling.

I am a construction newb, have a lot of questions.

Few questions I have right off the bat.

The exterior has vinyl siding with OSB sheating underneath. I am not sure if there is any house wrap installed under the siding. If I use paper faced fiberglass insulation, will I need house wrap between the insulation and steel?

How do I handle the outlets and switches? I have seen two options on youtube:

Option 1:

Leave the outlets where they are and cut holes in the siding to accept the boxes and standard face plate. Not sure how the outlets would line up with the ribs, and how to make that look decent.

Option 2:

Move the outlets a little closer to the breaker panel so I can rough out the electrical through the steel and then mount the boxes externally to the furring strips.

End goal for the building is to have a nice, clean, organized space for lawn equipment, four wheeler, and misc junk.
 
More questions:

I wanted the galvanized steel on the ceiling to add a little character, is that a dumb idea? Cost seems to be about the same.

How do you add inside corner trim to steel siding? I am coming up blank on options.

There is no access to the attic, best way to go about that?

You should be able to source inside corners for the siding.
 
I researched Metal panel materials extensively for a barn/shop roof project this spring.

The silver raw galvanized look is called galvalum(e) and is the cheapest color- Ag panel in 29 ga will be cheapest material at around 60c/sf around here;

you can Use this webstore linked below familiarize yourself with the product names and trim styles/materials available then generate a materials list and shop quotes from your local suppliers.

for example here is what gunracer refers to above:
 
I wish we had a shop and tools forum. :flipoff2:

The receptacle boxes on my shop are recessed and screwed to furring strips. Those metal boxes look good but take up a lot of space.
 
House wrap goes outside.
6 mil vapor barrier inside.
That is just plastic sheeting? That is easy enough.

Cool, I will look into it. Thanks for the info.
 
Why not sheet rock it? If you're not running an indoor grow I don't see it being an issue again
 
Don't use the paper faced insulation with plastic. Its one or the other. Paper face and no plastic or unlaced insulation and plastic.

Congrats on the new place. looks kick ass for a guy and his dog. :smokin:

about putting tin inside your shop......don't.

If you plan to work in the shop at all with any kind of loud tools, you will hate it. I had a 40x60 with the entire inside done in metal. it sucked. giant freaking echo chamber. my new shed has spray foam 6'' thick over the entire inside of the exterior tin(walls and roof) then I put up 3/4 osb 8' high from the floor. shop is much better for noise now.
 
I surface mounted my outlets and ran conduit , makes a good place to hang shit.

Ceiling panels I ordered 21ft for a 36x60 , I was not planning on installing it but ended up doing it, 21 was a bit long to handle.
 
OSB panels everywhere instead of steel.
Easy to work with, easy to rework, easy to paint white and keep clean.

No idea on the vapor barrier and actual technical details sadly

I have OSB and it's definitely not easy to keep clean aside from repainting.

Interesting.

The end goal is to have the small shed be mower, atv, pit bike storage. I just want it clean and tidy. I don't plan to work in there.

I am in the planning stages of building an actual shop shop. The echo chamber gives me something to think about though.

My OSB wipes down nicely. I sprayed it with 3 coats of semi-gloss floor polyurethane. I went with the OSB because I like the way it looks. It would have been nice to do 5 coats.

That being said, I would like to put tin or sheetrock in in my welding/fab area. The fire hazard worries me.
 
I'm not a fan of OSB for a wall treatment. I think it collects most of the worst qualities of both drywall and metal. Its still porous and so not impervious to mold/mildew, needs to be painted or makes for poor light reflection and easy staining, and screws will pull through it with minimal effort.

If you insist on wood, I'd put plywood sheathing up since its not much more expensive than OSB in the current market.

easy to paint white

I'd dispute the easy part, but it is indeed paintable with some effort. In my experience it soaks up like 3 heavy coats of paint until it absorbs enough paint enough to not appear overly splotchy.
