This garage has been a dream of mine since I bought my house in 2017. I started with a some tree clearing and stump pulling, decided to go bigger and did more tree falling. Finally in the winter of 2024 I decided to begin making real plans and architectural drawings to start the build in the spring.

Got some cheap architectural software to start creating layouts. This is close to the final product:

The location on my property where I wanted to place the garage had some significant grade , so I knew the foundation would require some careful design. I asked my dad (civil engineer) to create the foundation plans for me. We had done a detailed survey of the lot the summer before.

I went out and bought a copy of the IRC so I could start on the architectural drawings and make sure I made everything code compliant!
Quick sample of the drawings:

Met with the town building inspector to discuss , he signed off without issue!

I had not intended to do all the work myself at this point, I started gathering quotes, and I was in for some sticker shock! For context I am located in southern NH.

First quotes were for a “Weather tight” structure, no electrical work. Came in at $170-190k.

Next I wanted to see what framing labor only would be: $65k

And finally foundation only $40-50k.

Certainly I was not expecting numbers even close to that.

I ended up signing up with one of the concrete contractors, since I knew at least I would want that done by the pros.
He got started and I continued to plan out materials and learn framing ( a lot of reading and watching videos).

Foundation finished on July 3rd, and I started framing on the 4th!

Bought engineered trusses , rented a man lift and moved the trusses up one at a time. Also built a temporary wall in the middle of the room to facilitate easier truss installation.

Ended up hiring a roofing contractor to finish sheathing and shingle the main roof. I was getting pretty burned out at this point and needed to take something off my plate… so I let them finish that while I built and shingled the shed roof!

Digging the trench for electrical conduit.

Electrical is mostly complete for the winter, nothing really on the second floor and only minimal lights and outlets on the main floor. But the garage doors open and close, and I can plug in my truck.

Progress to resume spring 2025 with vinyl siding.

I have a ton more pictures and I am probably forgetting a bunch, so ask me anything!

Wow!! You just built a house!! Good work! With the trenching, your soil looks very sandy!

I’m very impressed you were able to accomplish this by yourself.
Thanks! It was quite the summer project.

Not entirely by myself, I had friends over for setting the girders and then later, the trusses.

It is just about a house, haha. Eventually I want to finish the upstairs into a full apartment.

Yes, the soil is very sandy, there is a small stream on the property, I think it was larger at one time. Mostly everywhere you dig it’s just yellow sand and gravel.

After the long winter I got going again on this garage build.

Since posting last, I got the electrical complete and inspected. Insulated the 1st floor, and installed a mini split . Working on siding now, which is ~85% done.

Got to add some new tools to the collection for the HVAC and aluminum trim work, having never done that work before :) .

Nice work! Tell us more about the insulation you went with?
Thanks!

The insulation is nothing special, just faced Owen’s Corning fiberglass r19. I bought rolls instead of batts, wall cavity is non-standard height.

I know there is some controversy with the faced flaps getting stapled inside the bay, or on the face. Supposedly stapling to the face of the lumber makes a better vapor barrier, however can make drywall install a little more difficult. Since I don’t care if the drywall comes out perfect I opted for the face staples. I guess I’ll find out if if what they say is true :)
