    I have a huge house and yard, and I wanted something that would compliment it. This was a great option, I’m thrilled with the finish product. My wife is glad we saved so much money on the plans, I was quoted $3500 from our local architect.

    I bought this 3 car garage, and when I took it to planning they said it was too big for my yard. I was super disappointed, I fix old cars and wanted the biggest possible garage. accr-rated sent me the 2 car instead at no extra charge.

    This was my top choice for a new garage, but I really wanted a single garage door and a double garage door. I emailed Accu-rated house plans and they said they didn’t have that option. I bought the expensive plans with the electronic version. I took them to a local draftsman I found on craigslist, he changed the door for me and only charged me $75!
