Here are a couple of pictures of my carriage house. One is when I had the Gravely, now replaced by my 2004 JD 4010; the pic shows it open at ground level and also the Gravely with some implements in the basement. The other picture has one part of it showing the basement of the carriage house where the implements are. (The other part of the picture just shows a breakfast room that was redone with the same Hardy Plank exterior.)
This carriage house was built for $40,000. The builder says he couldn't do it again for less than $100,000. The basement is tornado proof with VERY thick roof and sides.
