About Us

Design Evolutions Inc., GA is a building design company operating in Snellville, Georgia (metro Atlanta). Founded on January 4, 1999, the business began as a residential drafting and design company. Services included drafting construction documents for home builders, architects, other designers, as well as designing custom homes for local builders and private homeowners.

In January of 2000, Design Evolutions was incorporated and became a full service building design company focusing primarily on the creation of ready-made house plans and residential design service. Later that year, Design Evolutions began publishing a collection of home plan designs on a national basis through several popular internet publications. Our house designs are now published on a limited number of broker websites in addition to our website. Today, Design Evolutions continues to develop custom home designs for home builders and private clients throughout the United States.
