What TR,i Architects does

TR,i Architects is a private, full-service architectural firm founded in 1989 and headquartered at 1790 S. Brentwood Blvd. in St. Louis, Missouri. The firm provides architectural design, interior design, and consulting services across eight vertical studios: Commercial, Educational, Healthcare, Hospitality, Industrial, Institutional, Interiors, and Residential. Its core offering is project-based professional design services delivered to enterprise and institutional clients, with a supplementary design-build delivery model that integrates architectural design and construction under a single contract. The firm navigates municipal approval processes and develops prototypes for multi-unit franchise clients, exemplified by 60+ Starbucks locations across seven states.

The firm serves a diversified enterprise client base spanning defense and military (Leonardo DRS), grocery and food production (Dierbergs Family Markets), publishing (Pulitzer/Post-Dispatch), government and institutional (Jewish Federation, Missouri State Highway Patrol, Missouri S&T), hospitality (Marriott AC Hotel), healthcare (United Surgical Partners International), automotive (Lear Seating, Clement Automotive Group), and retail (Starbucks). Notable projects include the St. Louis Kaplan Feldman Holocaust Museum (36,445 sf, completed 2022), the AC Hotel Chesterfield (128 rooms, 60,000 sf, completed March 2022), the Leonardo DRS Bridgeton manufacturing facility (171,500 sf), and a recurring relationship with Missouri S&T (2011 renovation and 2020 addition). The firm received the 2022 St. Louis Business Journal Best Mixed-Use Project award for WildHorse Apartments and a 2003 Industrial Regional Excellence Award.

The business model is traditional professional services: project-based fees, quote-driven pricing, and multi-year contracts, with revenue generated per engagement. The go-to-market is direct enterprise field sales through RFPs, design/build competitions, and long-standing client relationships, supported by a digital presence on LinkedIn, Facebook, Instagram, and Twitter and a website portfolio. Recurring design/build partnerships with general contractors (Brinkmann Constructors, G.J. Grewe) and developers (Midas Hospitality) form a core distribution channel. Operating geographies span MO, IL, AR, IA, KY, NE, TN, and KS. The firm is privately held with no disclosed investors, funding rounds, or parent company, and operates with 11-50 employees.
