Hi Mary Beth, I've consulted a general contractor I use often who says that you should budget a minimum of $75 per square foot in the Augusta, GA area for the sunroom alone if the project requires electrical work but no plumbing work (we're assuming you don't want to install a wet bar or sink). He couldn't offer a masonry estimate, so you'll have to contact a masonry contractor for an estimate for your brickwork. Depending on the finishes in your sunroom, the actual per square foot cost could go much higher. The most important thing to do is to contact at least 3 general contractors for estimates who are recommended to you by friends and neighbors and then do a very thorough analysis of each contractor's estimate taking into consideration what each would be offering in terms of quality of work and finish. Don't be afraid to ask LOTS of questions.
