It will have a 5 car garage. One stall being 20ft wide (18ft door) and 42′ deep and the other 10ft wide (8ft door) and 21′ deep.
Cannot go any bigger because of city ordinance issues.
Sounds like I am more than good with 8′ height doors
If I can put me 2 cents in because I am going through another build right now. If you have 30′ of total garage width and 26′ width of doors your not going to have very much room along your walls at all to have anything along them. My last house had 2′ of room along outside walls and it sucked. Couldn’t even have my roller toolbox along the side wall. Lots of wasted garage space.
Also I would re-think an 8′ wide door if you plan to park anything midsize or better in it, after door trim you are going to lose almost 2″ of width. I had dual 9’W (2″ less with door trim) by 8′ high doors and even the 9′ was not very great. Backing a boat in that’s 8’6″ wide in wasn’t horrible but not great. Half ton pickup mirrors were pretty close also. 8′ height seemed to be ok, backed my MX2025 with 300 offshore in just fine and I could get my enclosed trailer in the garage and it just cleared the bobble vent on top.
My current house build is going to have one 18×9 and one 10×9.
Sounds like you are limited in square footage by your city but figured I would give my 2 cents.
