For $$$ your name here
I would think your utilities will be quite high with that setup, as you are always using fresh make up air. Of course sharing a common wall between the garage and house might more than offset the increased utilities.

Not enough time
I run a unit heater - reznor 80k btu. It's enough to keep the shop 70* when its -20* outside . I'm sure it would go higher but I have never tried. I heat my apartment separate . I build hospitals, airports, college housing, military barracks etc.. Government work. I end up with nice left overs from projects. All my walls are r38 or higher or 2 layers of r19 which I staggered the joints on plus the existing shop insulation which was probably equal to r10. If I build an entirely new building when this ones paid off I'll be going in floor with pex or the like.

Could be.. Seams it could go either way..
1/2-1psi pressure differential is enough to shut a door..

125K is very reasonable
This is exactly what I'm building. The shop is 40x64x16 fully finished interior with Spray Foam, 4" rebar concrete 4500psi, with a 12x24 lean to that is the office/bathroom.
Inside: bottom 8' will be FRP board, and the top 8' steel.
Apartment will be 28x40 2 story with a 1 car garage. 3 bed, 1.5 bath (this part is being built this fall)
This project will be near $125k all said and done.

Cummins. What else?
Commercially we try to keep our buildings 0.01"-0.02" positive.
More and more residential HVAC systems bring in and condition outside air to positively pressurize the house. Makes for a cleaner space and prevents 'sick houses'. A 5-ton residential unit is generally between 1800-2000cfm and 10% would be slated for outside air.
If you think about it, many houses are actually negative a lot of the time, dryers blowing exhaust outside, exhaust fans for bathrooms, vent a hoods, etc... The air is sucked in through door and window seals etc... Much better to pull it in through the HVAC system, filtered and conditioned.
Yes small utility impact, but a better system overall. And could help with the shop fume/dust infiltration problem!

Never enough.
Agreed. I have been doing a lot of the labor myself....and costs of living/labor is pretty inexpensive here compared to many area. But like all my projects, I'm sure I'll go overboard from what I planned. If I can keep it under $150k i'll be happy.
