Architectural Dimensions

What Architectural Dimensions does

Architectural Dimensions is a privately held, full-service architecture, planning, program management, and interior design firm founded in 1982 and headquartered in Oakland, California (operating out of the historic Rotunda Building since relocating from Walnut Creek in 2012). The firm delivers nine core service lines—architecture, interior design, program management, project management, construction management, master planning, agency management, information management, and communication management—and serves two principal customer verticals: branded hospitality developers (Hilton, Marriott, Virgin Hotels, Hampton Inn, OTO Development, Kade Development) and public-sector/civic clients (Port of Oakland, City of Oakland, California Capital Group).

Revenue is generated on a project-by-project basis through negotiated professional service fees, with architectural design fees running approximately US$20,000 per hotel key (translating to roughly US$2M+ for a typical 100-room Bay Area hotel). The firm has delivered or is delivering projects with a cumulative portfolio value in the hundreds of millions of dollars, including the US$1 billion Oakland Army Base redevelopment (as Program Manager), the US$87 million Fox Theater renovation (National Preservation Award, 2009), and the US$49.6 million Rotunda Building restoration. Geographic reach is centered on the San Francisco Bay Area and broader California, with selective expansion into Hawaii, Washington, and the Los Angeles metro.

The firm operates a sales-led go-to-market, relying on direct developer and brand relationships, RFP responses, industry event participation (BisNow panels, Why Oakland CRE Meetup hosting), and earned media in regional business publications. Pricing is not publicly disclosed and contracts are negotiated per project based on scope, complexity, and scale. There is no evidence of external institutional investment, private equity backing, or parent ownership; the firm is independently owned and led by founder and president Jim Heilbronner, with leadership including Margit E. Whitlock (VP Interior Design) and Erika Ramirez (Chief of Staff).
