Are you going to use the double or the single the most?

How will you use the 3 bays?

What will normally be parked in the garages? If you have a large SUV that will be parked in the double bay, I’d put the single closest to the street to give yourself more room to turn in with the big car.

I think we need to also know the arrangement of the driveway, of the interior space (how much space is there between the single and double?), and of the entrance into the house, as well as how the bays will be used (Including, do you do your own yard work and/or snow-clearing).

Thanks all. Snip is below. I would envision parking 1-2 cars toward the front of the garage. In the rear near the steps into the house, we would have a workbench and probably storage for bikes, etc. I like the idea of having the single door in the back if we wanted to get at toys, bikes, sports equipment, etc. Anyone think that's a mistake? Unfortunately there isn't enough space for a service door.

From the image you posted, I still don't know if the garage bump-out (at the bottom of the image) is facing the street or the back yard. At any rate, you still seem to have a spot for a pedestrian door, and you could put a workbench in the window bay (which would give you necessary light when working at the bench.

I would say it's depending on how you enter the garage. If the turn in is tight at all, I'd have it so your radius pushed you into the garage and not toward the wall for the single door. However - as stated - it depends. If you will use the garage and the weekend car occupies that bay, put it further away from the entrance to the house to avoid all the inhabitants walking past it with purses, groceries, packages, bikes, etc.

What are the garage dimensions?

I can't tell from the diagram and lately (last decade or more) builders are making the garage dimensions so tight that a 3 car garage is really only room enough for two cars and a little bit of storage - not 3 cars.

what is the depth of the garage? I would have your architect drop in your cars and look at the walk path as the stair direction requires walking in front of the cars to get in the house which means the car slot closest to the house is kinda useless and back wall cant be used for wall storage - maybe contact a local garage storage company like gorgeous garages to see if you can share plans and have them do a storage layout so you know what you have.

If the house is still in the design stages its a good idea to add a stairway inside the garage leading down into the basement.

Currently living in a rental with a garage that has no man-door. It’s awful. I curse at the garage all the time. I’d bend over backwards to figure out how to make that work. I’m not sure that the orientation of the doors matters that much really.

My personal preference is to have one door for each car. This minimizes the exposure of the garage every time the overhead door is open. A man door in a garage is paramount.

Definitely drop a car in there, and see if there is room to move the door to the house away from the corner 1.5-2”.

Where would you like to keep the trash and recycling bins? You don’t want them to block the man-door, but you want them easy to get to and easy to roll outside.

Layout similar to picture. We don't have a man door and I don't miss it. Our garage door has the key less entry which makes it easy for all of us to get into the garage.

The man door would just be another door to make sure it was locked. If I went out the back of the house and wanted something from the garage, you would need a fancy keypad entry to the man door or carry a key.

Where is the front door and where will kids run out to the carpool car? A man door in this layout would make it difficult to wait at for a ride.
