So am I crazy with my new garage plan?

[MonzaRacer]

Was wondering about any thoughts on building pole barn garage with second floor to make livable, at least temporarily.
My plan at first was nice 24wx32l building. plan for good concrete floor, 6-8" so I can have lift.
Basiic pole barn plans all call for 8 foot on center posts. I thought maybe up grade posts to proper 6x6 set in concrete( use proper UC4B posts and such and rot is not a problem. My plans were to see about 4ft or 6ft on center, frame for side garage door and end garage door and entry doors and windows later on, Possibly finding over stock or take outs for garage area.
Then my plan had been as I build the building and walls are up start putting 16" engineered floor trusses in ceiling, then build 6-8' tall upper room. Nice bath/bedroom on one end, kitchenette on other. MAYBE single shower/urinal at other end in corner, near kitchen and entry door. come in have washer/dryer right there.
Figured all kitchen stuff along one end ,maybe small bar to eat at.
Living space be open as much as possible.
Simply finished as I can, with open concept that I can section off as needed inside.
The trusses have hvac/plumbing runs to go through so do that as I can, have local heating and cooling people run floor duct through center of truss, maybe 3 to 4 branches towards wall.
My plans had been to add couple of wall propane heaters with proper fire protection (off when not home) and use down draft furnace from trailer(its nearly new) to heat upper level.
Plans were to do a lot myself or as funds allow use local contractors to do certain parts of project.
electric I had plans to just use same meter and run to both upstairs and down stairs boxes.
Figured look around for decent deal on the romex and just buy large role to wire building with. Bathroom only needs couple outlets, smae on bedroom.
In living quarters figured 6 to 8 outlets max.
Kitchen would need, dryer, washer, stove, 4-6 outlets max.
The idea is keep it simple yet livable till I move on, as in possibly build small 1 floor on slab stick home elsewhere on small plot I have.
My idea was keep garage area basically enclosed till ready to finish it out THEN open up garage doors opening(already framed but not open).
If garage area is closed off and floor is properly insulated I should not have issues.
Fellow I work with has buddy with extra windows and doors from his project I might get cheap to get them out of his way. Which would set me up for upstairs.
I can live with bare dry wall and such and throw rugs to start. Plans are get it up right and ready, move crap in, get rid of my trailer and re landscape rest of property.
Throw up ideas, planning sites, etc.
Basic idea"
24' wide north to south, 32 ft long east to west. Figured building total to eaves height 22-24' +/- then roof.
Open ceiling with scissor trusses so no dead space, just heated and insulated to roof.
Open concept, basically 12x12 bedroom/bath on west end. 24'x24' for living space (me and my cat) entry on south side near east endcoming up from old deck next to my trailer,just add in stair strinnger up.
Maybe another door,stairs down on north side, not sure.
Basically kitchen stuff, along north west end. small shower/urinal on south west end, possibly washer/dryer right thier.
Still planning and such.
Dont have much in codes here and septic from trailer will line up with west end of building. Water and electric can come from east end.
Sorry if my post is disjointed, Im thinking and planning as I type.
But help,ideas,criticisms welcomed.
