About Us

In 1971, James Lamphere joined Richard “Dick” Wiemann in establishing Wiemann Lamphere Architects. The two were successful in building a considerable design practice and becoming leaders in the design community, in and around Vermont. 

In 1985, the second generation of partners was established with the offering of a partnership to Gary Lavigne, a native Vermonter who went to the Boston Architectural Center and practiced in the Boston area, as well as Dennis Webster, a graduate of Colgate University who practiced in Ohio. 

Richard and Jim went on to retire in 1994 and 1998, respectively.

David Roy, a native Vermonter and graduate of Vermont Technical College and Kansas State University, did his internship in Wichita Kansas prior to starting with Wiemann Lamphere in 1994. David accepted a partnership in 2001. The following year, David’s brother Steven Roy joined the firm. Steven is a graduate of Wentworth Institute of Technology in Boston and worked in Boston for two years before moving back to Vermont. By 2008 Steve also became a partner, establishing himself and David as the third generation of partners at Wiemann Lamphere Architects. 

Dennis Webster retired in August 2014, and Gary Lavigne retired in May 2016.  

David and Steven Roy began spearheading the firm’s new direction with renewed focus on sustainable and environmentally friendly architectural design, while continuing the firm’s long history of design excellence across multiple industries and functions. 

In 2017, Kelley DesRoches, a graduate of Roger Williams University, joined the team, bringing with her 20 years of experience in architectural design work and a strong background in interior design. She became the newest partner in March 2023, establishing herself as the root for the fourth generation of principals at Wiemann Lamphere Architects.

Together, David, Steven, and Kelley are building on a solid foundation of quality projects while focusing on providing leading edge, dynamic and sustainable architecture for today’s world.

Design Philosophy

Creative, sustainable design solutions that respect the environment, the building’s occupants, the budget, and the timeline

— our mission, and our promise to you.

Successful design is functionally effective, aesthetically pleasing, and environmentally sound. It makes a statement about a commitment or brand without making a lot of “noise”. Wiemann Lamphere makes every effort to design architecture that fits this criteria. We craft creative solutions that integrate and fit within the environment,  withstanding the test of time and remaining beautiful and efficient for its lifetime. Collectively, we address and incorporate your needs while employing the latest sustainable technologies to improve quality, reduce costs and continue our commitment to environmental preservation and global climate change mitigation.

At Wiemann Lamphere, we understand every project impacts the environment, economy, health, and productivity of its inhabitants and surrounding area. We are among a growing number of building and architectural design professionals who develop high-performance, sustainable buildings. Our five LEED Accredited Professionals implement sustainable practices and design features into each project. Our staff works collaboratively with owners, design professionals, contractors and all project stakeholders to develop projects that perform at high levels and set new standards across the five essential Sustainable Design Categories - Sustainable Site; Water Efficiency; Energy and Atmosphere; Materials and Resource; and Indoor Environmental Quality.

Sustainable building development is an opportunity to improve lives, address social issues and revitalize urban and rural areas. Designing a housing development involves careful consideration of all aspects of a neighborhood and the people who will live there. We work with our clients to look beyond the individual building structures and focus on environmental impacts, mobility of pedestrians, traffic flow, aesthetics from all directions, and more.

A successful project starts with a fundamental understanding of the issues involved, the project constraints, and the client’s needs and requirements. We will listen to you and establish the parameters and scope of the project from the beginning, as the project develops, and use these parameters to guide the decision-making process along the way.
