[Planning Stage] 24x60x20H Post Frame Building w/ Loft

[NitroGarage]

I've been doing a LOT of reading on here lately and I'm looking to build my own workshop in the back yard. Due to the lay of the land I'm limited to something 24-30' wide and can go back 60' or so before I get close to the septic leach bed lines that run diagonally across my back yard to the back left corner of the lot - I do NOT want to get into relocating that mess.

Rough plan thanks to Menards planner tool:

The reasoning behind the height is for framing in a full second floor above the 14' shop which I will be installing a lift in down the road. With the span only being 24 feet I can use engineered lumber to clear span it without a 60' center beam or add supports. I will need to consult with them or whomever ends up doing the final engineering on this in regards to scissor trusses to open the ceiling height up on the second floor as well as column loads with a second floor applied (for humans and light storage only, no engine blocks, there will be pallet racking for that). Although, after doing some math, it appears the compressive strength of the posts is more than adequate and them going from 2x6 lam columns to 2x8's is mainly for side loads at this height than compressive loads that a second floor would apply.

Now I'm most likely going to need to figure another foot higher because a 14' door won't open up into a 14' ceiling which I'm mandating for the ability to put an RV or semi in the main bay.

Floor heating. After building my brother's place with it I won't not have it.

Those that have a long narrow garage, what are your gripes and what would you do differently?

I'll post up an aerial photo with a rough layout showing land features and what I'm thinking this evening.

I would suggest if cars go in the building to be looking at 30 feet or wider. I think you are going to be disappointed at only 24 feet deep. But then it is your money, not mine.

Good luck!

Do you really think a full two story building with 21' sidewalls is a good fit for pole barn construction?

Personally I think you are at a point where it makes more sense to build on a foundation, frame a first floor, frame a second, roof it and call it good.

Sure it can be done, but by the time you add everything to float a floor in there, and finish it beyond some metal siding, it isn't going to make sense imo.

I've got a couple feelers out to engineers at pole building firms to verify.
