A Leader In Innovation

  • In 1978, after reading an article entitled “38 Reasons Buildings Often Fail” Lloyd Reaves, with his years of experience in mobile home manufacturing and sales, realized that wood truss technology could be the solution to all the reasons why buildings fail. After spending many years perfecting the process of applying wood truss technology to other building components, such as wall and roof brace panels and special columns, Lloyd was awarded Patent #4,468,218 for his invention. This tradition of innovation and progress has lead Reaves Building Systems to develop four styles of totally engineered buildings that use this exclusive technology: The Reaves (RB-R), the Modified Reaves (RB-MR), the Silas (RB-S), and the Douglas (RB-D).
