If you are doing new construction, a courtyard entry is better than a back entry as you can build more turning radius into driveway. Always have big door on outside with door height of eight foot. Try and have at least 28' of depth. Additional width is also helpful
Don't skimp on size of driveway as tuning radius is very key to access on a side entry garage. I have a 30' deep side entry garage. If I was to do it over again with same house design and lot, would go 28" depth with more driveway, but make garage wider with a 18' door.
The single car garage door needs to beat least 10' wide to be useful on a side entry.
Add fan over boat and lots of lights. The new LED's are wonderful.
