Building Graphics, Inc., designs family homes. In the 1990s, BG designed three plans that were later sold to other builders. Two of the designs were used to build a pair of houses (one per design) in the Charlotte area. The designs were also available online for purchase as “stock” plans. The third design’s plans were available offline for sale. All three were copyrighted.
Lennar Corporation builds homes in 18 states. Before jumping into a market, they conduct “due diligence” of recently built homes in the area, which includes analyzing floor plans, features, and prices. However, Lennar maintains that it is limited to homes currently being built and sold, not completed examples.
