rhizaFAB is

A sister company of rhiza Architecture+Design. As a prefab and construction company we bring deep experience in custom fabrication, metalwork and prefabricated building systems. Our practice sits at the intersection of art, architecture, and construction—where technical rigor supports creative expression.

With a background in complex fabrication and on-site installations, we understand the full lifecycle of a project: design intent, engineering constraints, fabrication realities, transportation, and installation. This holistic approach allows us to solve problems early, streamline timelines, and maintain quality from shop floor to finished build.

We are known for our collaborative process, clear communication, and ability to deliver highly customized work at multiple scales—from public artworks and architectural metal features to compact, thoughtfully designed pavilions, studios and dwellings.

We Provide

Prefab, fabrication and construction services that bridge design, engineering, and craftsmanship. From detailing to the final installation, we specialize in translating ambitious ideas into durable, buildable, and beautiful structures. 

Our work spans custom metal fabrication, architectural features, public artworks, and prefabricated building systems. We collaborate closely with artists, architects, designers, engineers, developers, and private clients to deliver solutions that are structurally sound, aesthetically refined, and tailored to their specific site and use.

Whether producing a one-of-a-kind sculptural artwork or a repeatable prefabricated system, we focus on precision, material integrity, and long-term performance.
