design for a better world

We are community design innovators. Over the last 50 years we have built a practice based on integrity, collaboration and trust, creating innovative and original human communities.


Donald C. Westphal established a small land planning and landscape architecture firm out of his Rochester, MI, home in 1969. However, his passion for manufactured home community design soon became the flagship of his business, providing a level of service rarely seen in the industry.

His firm soon grew into eight full-time employees, becoming one of the nation's foremost authorities on manufactured home community design. Simultaneously, the firm also expanded its services to include single-family subdivisions, RV resort design, high-end recreation facilities, commercial developments and resorts.

Don’s commitment to design and planning excellence in these areas has been recognized by respected industry publications and trade shows. Developers, manufacturers and designers alike travel across North America to listen and watch his lectures and presentations, hoping to engage his services for their projects.

MHI has awarded Don the Land-Lease Community of the Year Awards seven times at its MHI National Manufactured Housing Congress & Expo. They also inducted Don into the Manufacturing Housing and Recreational Vehicle Hall of Fame in 2006.

Don has served on the MHI Board of Directors through his leadership positions as Vice Chairman and Chairman of the MHI Suppliers Division, and Chairman of the Manufactured Housing Educational Institute. He has represented the Michigan Manufactured Housing Association on the board of governors of the MHI National Communities Council and the Federated States Division, and served as chairman of MHI's Site Development Committee and co-chaired MHI's Urban Demonstration Project.

Don has been a member of the Michigan Manufactured Housing Association since 1969. He has served on the MMHA Board of Directors, the MMHRVCA Executive Board of Directors, numerous committees and task forces for the association, numbering over 20 years of association service.

He now manages two other employees at Westphal Associates who possess a wealth of experience in consulting and design services to meet clients’ needs.

A Note From Don:
"It's amazing how time flies when you're having fun! For nearly 50 years, we have had the privilege of participating in the planning of several hundred thousand homesites, RV campsites and many other development projects across this beautiful country. I don't know what life would be like if we did not have an exciting and challenging project on the next day's agenda. We cherish our role in changing the face of the earth for the better, one parcel at a time and are proud to have created so many environmentally sensitive site plans and attractive images.

We look forward to the future and our next challenging design with the same enthusiasm and excitement we felt in the early stages of our career and would be honored to bring that excitement and commitment to your next project."
