How do I get a new garage built?
There are contracting outfits that specialize specifically in doing garages. I used one to build me a 28x36 foot garage that had the capabilities to do all the work of preparing the site, making the foundation and floor structure and building the garage itself which they were happy to customize a bit as to where I wanted windows and service doors. When the garage was finished they were there to lay down a huge new driveway.
