What Teass Warren Architects does
Teass Warren Architects is a Washington DC-based architectural and interiors practice, co-founded by Will Teass (Managing Principal) and Charles Warren (Principal of Design), operating from 609 H St NE Suite 600 and serving the Washington DC metropolitan area including Northern Virginia and Maryland. The firm delivers full-service architectural design across custom single-family residences, multi-family and affordable housing, mixed-use development, commercial and retail projects, historic preservation, and adaptive reuse. Its technical approach centers on sustainability-integrated, high-performance design: documented work includes Energy Use Intensity as low as 1.9 (versus a typical DC rowhouse target of ~30), 88.6% solar energy offset in year one for the NetZero Rowhouse, and certifications across LEED for Homes Gold, EnergyStar, EPA IndoorAirPlus, Zero Energy Ready Home, and Arlington Green Home Choice Silver. The firm is a DC-Certified Business Enterprise and is aligned with the AIA 2030 Commitment through its 2025 Sustainability Action Plan.
The firm has developed proprietary expertise and research tools tailored to DC's regulatory environment, including SINGLECORE, a research framework and design typology for single-stair multifamily buildings that quantifies more than 5,200 eligible infill sites and over 11 million square feet of potential development in DC. Leadership actively shapes local zoning rules: Will Teass testified before the DC Zoning Commission on alley lot reforms in 2026, and both principals serve in AIA|DC advocacy leadership (former AIA|DC President and CRAN Co-Chair). The firm pairs these capabilities with deeper sustainability offerings like LEED consulting and high-performance building modeling (via partners such as Jay Hall and Associates) and complements design work with landscape and interior collaborators including Studio Sophiste, Studio AKA, and Clinton Ries Landscape Architects.
Commercially, Teass Warren operates as a professional services firm on a project-based, quote-based engagement model. Revenue derives from architectural design fees for custom residential work for high-net-worth homeowners and from commercial/multi-family developer clients across the DC region. Client acquisition is sales-led, relying on referrals, professional reputation, digital content (blog/Journal articles on zoning, sustainability, and design), an active Instagram presence, an email newsletter, and industry participation (AIA conferences, career fairs). The firm's productized offerings include Custom Home Process Guides, LEED certification consulting, and an Investment Property Development Consulting service targeting developer/investor clients. Pricing is not publicly disclosed and is determined per project.
