You would get the best answers to all your questions if T & D was one of those giving you an estimate. They build the pools for The Villages and have done thousands of birdcages and pools in TV. The one negative is they are very busy, pools are sometimes a 4 month wait for start time. My neighbor got a birdcage from them, he's very happy. He found out his CYV backyard needed for the cage to be 10' from the property line, they knew that, and made the adjustments when giving an estimate.
