Yep, agree with most everyone... 7' tall doors suck... single doors seem better for cars, large double-wide door better for junk...
2 car attached and workshop detached seems to work out well for me and several others...
More utilities would certainly be a plus...
Mine is 24 x 34 with a large double-wide door on the 24 side that faces the street...
We're in an older-ish subdivision (1974 is relatively "older-ish" for real estate, right?) but my shop was built in 1994... but here's the key... subdivision WITHOUT HOA FEES... I was not kidding around about that with my better half, that was a deal breaker for me...
Set up that expectation early and it will help with the "Oh, Honey, this subdivision without trees and houses stacked like pancakes is sooooo beautiful, isn't it?" conversations...
FWIW, they marketed my 24x34 garage as 4 car plus the two car attached, makes 6 in the MLS listing... I found it very easy to filter MLS listings by garage... and we looked passively, actively, passively, actively for over 9 years... (hope that doesn't bum you out... the right place is there to make everyone happy... just a matter of time to find it)
