Builders recommended, middle tennessee

My wife and I are looking to begin construction around July or August of 21, and we're looking to build a large, simple 3 bedroom 2 bath barndominium with a large attached shop. We want a simple, open living space in the center with the kitchen, living room and dining room combined, two bedrooms on one side sharing a bathroom in the center, and a large master bedroom and bathroom on the other side, with the garage/shop on the back side of the house. We want sturdy, simple construction, and the potential to easily add access for those with disabilities. A solarium may be a possibility if the budget allows.

Can anyone point me in the right direction?
