On the interior, you have a painted drywall finish with two parking stalls; each measuring 18′-8″ deep x 9′-4″ wide.

Access to the garage comes from a dedicated garage entrance off a 36″ wide side entrance door or through the dual 8′ wide by 7′ tall rolling overhead garage doors.

Windows are placed at 42″ above the concrete floor making a workbench or freezer can be made to fit in nicely beneath.
