What Wiemann Lamphere Architects does

Wiemann Lamphere Architects, Inc. (WLA) is a privately held architecture firm founded in 1971 and headquartered in South Burlington, Vermont, with a second office in Manchester, New Hampshire. The firm employs 17 staff, including 15 design professionals, six of whom are LEED Accredited and one of whom is Passive Haus Certified, and is led by principals David Roy, Steven Roy, and Kelley DesRoches alongside design director Michael Minadeo. WLA provides comprehensive architectural design, planning, and construction administration services across four practice areas: municipal (libraries, city halls, public safety facilities), hospitality (resorts, distilleries, hotels, restaurants), residential (multi-family, senior, vacation), and commercial (offices, mixed-use).

WLA's core technical differentiator is sustainable architecture: the firm designs net-zero energy buildings using biophilic design principles, solar photovoltaic systems, geothermal heating and cooling, and mass timber construction, with the goal of eliminating fossil fuel use in projects. In-house LEED administration is performed by the firm's own accredited staff rather than outsourced consultants. Notable projects include the South Burlington Public Library + City Hall (50,000 SF, geothermal heating, 150 kW solar array, LEED Gold seeking), the Barr Hill Distillery (83.7 kW DC photovoltaic system), Jay Peak Stateside Lodge (86,000 SF), Mount Snow Carinthia Base Lodge, and the Bayview Crossing senior housing development.

The firm's business model is project-based professional services. Revenue is generated through architectural design fees tied to project scope, complexity, and requirements, with no publicly disclosed pricing or recurring revenue streams. Projects are acquired through competitive bids, RFPs, design competitions, and client referrals, supported by an award-winning portfolio (multiple Efficiency Vermont Best of the Best awards and AIA Vermont Excellence awards), a content-driven website portfolio, and professional networks. The firm is independently owned by its principals with no institutional investors, parent company, or acquisition history.
