What Miller Dunwiddie does
Miller Dunwiddie is a full-service architecture and design firm headquartered in Minneapolis, Minnesota, founded in 1963 and organized as an employee-owned company under an ESOP established in 2016. The firm delivers architecture, interior design, and planning services across seven practice segments — Aviation & Transportation, Education, Faith-Based, Historic Preservation, Workplace & Commercial, Public & Civic, and Building Science — serving enterprise and institutional clients on projects that range from airport terminals and light-rail stations to campus buildings, religious facilities, and historic rehabilitation. Its technical stack centers on mainstream AEC tools (Revit, SketchUp, Adobe Creative Suite, Enscape) and specialized performance-analysis tools (Flixo, Autodesk Insight, Tally), complemented by a dedicated building envelope/forensics group and a preservation practice operating since 1970 under National Park Service Professional Standards.
The firm's revenue model is professional services: fees are earned for programming, predesign, master planning, design, historic preservation consulting, building envelope/forensics, interior design, and construction administration. Pricing is quoted project-by-project based on scope and complexity and is not publicly disclosed. Go-to-market is enterprise field sales — direct engagement with clients through relationship development, proposals, and participation in civic and professional associations (AIA Minnesota, USGBC, ACE Mentorship), supported by a corporate website, social channels, and case-study content. The firm is a signatory to AIA's 2030 Commitment (since 2017), targeting LEED Platinum/Gold, Minnesota B3/SB2030, and International Living Futures Institute Zero Energy certification outcomes.
In November 2024, Miller Dunwiddie acquired Bentz Thompson Rietow (BTR), a 50-year-old Minneapolis firm focused on public projects for higher education, parks, and libraries; BTR President Ann Voda joined Miller Dunwiddie's leadership team. The combined firm operates from a single Minneapolis headquarters (100 Washington Ave South, Suite 500) with a hybrid work schedule, maintaining the BTR brand alongside the Miller Dunwiddie brand. Notable named clients include MSP International Airport, Jackson Hole Wyoming Airport, Metro Transit, the University of Minnesota, Benilde-St. Margaret's, Waseca County Courthouse, and Berean Baptist Church.
