Based in Concord, Massachusetts, The Windermere Group, Inc. has been renovating and building custom homes since 1987. Patricia and John Austin of England began in the construction industry by doing small remodeling projects. The company began to see success as they started building custom homes. Quality is a must in a Windermere home. We don't just build beautiful homes, we build homes with integrity and strength. We pay attention to details that can't be seen as well as the details that can only be seen by the experienced eye.
