Founded in 1979, RDC is a 160-person architecture, planning, and interiors firm whose San Diego office operates out of the historic Lloyd Ruocco-designed Design Center on Fifth Avenue. The firm leads retail, mixed-use, grocery, hospitality, and entertainment work nationally from offices in Long Beach, San Diego, Washington D.C., Bentonville, and Phoenix — a national multi-office footprint distinct from the single-studio scope of DGA planning | architecture | interiors. The San Diego studio is currently designing three mixed-use high-rise multifamily residential towers in Downtown San Diego and delivered the ongoing redevelopment of Fashion Valley and the transformation of Horton Plaza. Store-planning and retail-rollout services build customer-journey mapping, visual merchandising strategy, and prototype documentation into the architectural package, work that frequently coordinates with public-realm designers including Sotelo Landscape Architects. Recent typologies include adaptive reuse of historic department stores into destination grocery and wellness anchors — the approach taken on the former I. Magnin building in Pasadena — and cannabis dispensary design. Master-architect commissions for regional shopping centers are the firm's most complex delivery, resolving tenant coordination, phased construction around operating retailers, structured parking, and landscape placemaking across multi-block sites.
