Designing new garage

I am looking for some advice on door spacing for a garage I am planning on in my backyard. Planing on 4 bays that are double deep. I was thinking of two 9' and one 18' garage door on the front with 5' spacing between them and the side walls (see drawing). Told at least one double door is a good idea. This makes it 56' wide. Was planning on 46' deep. 12' ceilings for a lift. Wondering if I need the 5' spacing but hope to be able to have some cabinets on the side walls and have room to open doors without worry about hitting another car or the wall.
Some questions are: Should I space the doors closer (4') and have more on the sides (6')? Is the depth enough? Have 2 full size pickups would like to include a bathroom and sink somewhere too. Was thinking of a 2 or 4 post lift in one bay, probably the right 9'. Looking into 10' and 20' doors if possible. Interested in insights from anyone who has been through this process. Am taking to the designer next week. I am limited by the depth as have a max roof height of 16' (will be exactly this with 2/12 slope) and don't want a flat roof.

Would be grateful for any advice.

Thanks for the quick reply. Now for a very ignorant question: What is Silver?

 

Thanks! I didn't even realize there was a separate subscriber forum. Done.

 

Thanks to both of you for the advice. I appreciate it. I am now thinking of going to 10' doors (my F-150 is 8' at mirrors) and moving them in a bit to provide more space at the walls. This will help with shear too. Am planning on a 2 post lift in probably the back right bay but ceiling will only be 12' (actually probably 11.5') so will need to figure out some way to vault the ceiling around it to get a higher lift model. My neighbor recommended the 18' door, said it is nice with larger vehicles (he has several vintage Cadillacs) to be able to pull in without concern for the sides. Thinking about a drain in the center for washing cars inside (would be great in the summer!) Hopefully will get some preliminary drawings next week. One challenge is I am limited to a mx height of 16' but want 12' ceilings. Will need a 2/12 pitch roof which will be a challenge to make stylish.( a requirement of my wife, otherwise I would have gone with a metal building!)
