What Kuth Ranieri Architects does

Kuth Ranieri Architects is a privately held architectural practice founded in 1990 and headquartered in San Francisco, with a secondary office in Massachusetts. The firm delivers full-service architectural design — from master planning through construction administration — across residential, commercial, institutional, municipal, aviation, wellness, and cultural sectors, with a stated specialization in climate-responsive and sustainable design, adaptive reuse of historic structures, and net-zero energy systems. Core services include architectural design, climate action and sustainability design, master planning and urban design, historic preservation/adaptive reuse, and interior architecture.

The firm operates a project-based professional services model, generating revenue through customized fees that vary by project scope, complexity, and duration. It accesses large-scale commissions primarily through joint ventures and associate-architect roles with major firms such as Gensler (SFO Big Room, Chase Center Stadium) and SOM (SFO International Terminal Refresh), supplemented by direct engagement with institutional, governmental, and private clients. Its proprietary Folding Water™ ventilated levee concept, which won the 2009 Rising Tides International Ideas Competition, exemplifies a parallel R&D track focused on climate-adaptive infrastructure, alongside conceptual projects such as the Climate Clock and Micro-Hood.

The firm has accumulated multiple AIA National Honor Awards (2006), regional AIA honors, and Spark/Architizer recognitions, and has delivered LEED Silver-certified projects (Tooth Spa 2008, SF Green Dental 2009). Its portfolio spans 50+ completed and in-progress projects on both U.S. coasts and selectively internationally (Shishan Aviary in Suzhou, China). The practice is principal-led by Byron Kuth and Liz Ranieri, with no disclosed external investment, subsidiaries, or holding-company structure.
