In recent years, Los Angeles has become a hotbed for innovation in prefab architecture. From tech-driven ADU designs to next-gen panelized wall systems, new construction techniques are producing prefab homes that are more energy efficient, resilient, and beautiful than ever before. We’ve rounded up nine prefab companies in Los Angeles spearheading the effort.

Minarc

Fueled by a commitment to environmentally friendly design, Santa Monica–based Minarc is best known in the prefab world for creating mnmMOD, a wood-free prefabricated wall system that can be used to make durable, energy-efficient homes ranging from Icelandic-inspired tiny houses to spacious family residences. Designed to exceed Title 24 standards, mnmMOD panels are made from Cradle to Cradle–certified extruded polystyrene (EPS) insulation and 30% recycled steel, and they are not only free of harmful VOCs, but also resistant to fire, mold, and warping.

Sander Architects

Rooted in the belief that efficiency is an essential element of beauty, Marina del Rey–based Sander Architects have developed a new building method that they call “hybrid construction.” Designed to be more cost-efficient than traditional site-built construction, the approach combines the advantages of prefabricated components with the flexibility of custom builds to create one-of-a-kind residences that range from 2,000-square-foot urban homes to 10,000-square-foot rural retreats. The award-winning firm has completed hybrid construction projects all along the west coast and abroad.

Cover

Founded in 2014, Cover is a tech-driven prefab startup that uses computer algorithms to streamline the home building process—from design and permitting to final construction. The company focuses on creating flexible, modern ADUs, and they can produce custom designs in as little as three business days. Cover’s patent-pending building system and small build sizes allow for rapid assembly without cranes or heavy machinery.

Marmol Radziner

Since its founding in 1998, design-build practice Marmol Radziner has successfully tackled a variety of fields—from restoration work and interior design to custom furnishings and jewelry. However we’re particularly fond of the firm’s high-end prefabricated homes. Modern and minimalist, the luxury prefabs emphasize and enhance the landscape through their design and use of materials.

LivingHomes

Based in Santa Monica, LivingHomes is the design studio behind Amazon-backed Plant Prefab, and the firm has completed dozens of modular homes—including the nation’s first LEED Platinum prefab. In addition to fully custom builds, LivingHomes offers a wide range of customizable prefab models—dubbed the Standard LivingHomes—that include designs by Ray Kappe, KieranTimberlake, and Yves Béhar.

Connect Homes

Founded by Jared Levy and Gordon Stott, two architects who previously worked at Marmol Radziner Prefab, Connect Homes offers turnkey green homes constructed from patented modules. Their streamlined approach to prefab has earned them numerous accolades. Connect Homes currently offers ten models that range from 460-square-foot single-module homes to large ten-module residences that span upwards of 3,000 square feet. Each home is constructed to approximately 90% completion in their San Bernardino factory before it’s shipped off to the site.

Office of Mobile Design

For the past two decades, architect Jennifer Siegal has been a pioneer in the field of portable and prefab design. As the founder and principal of the Los Angeles–based Office of Mobile Design (OMD), Siegal has completed a variety of award-winning modular builds that range from mobile classrooms to the recently unveiled prefabADU series.

Proto Homes

Founded in 2009, Proto Homes combines their proprietary system of integrated component–based construction with their patented Hyperspace+Core system to create their prefabricated residential designs. Each of their contemporary prefabs features a flexible open-plan layout with a streamlined appearance. The company’s Proto Core is a “centralized factory-made engine” that houses all of a home’s key functions—from the HVAC and electrical systems to security and smart technology components.

kitHAUS

Using a patented M.H.S. aluminum construction system resistant to rust, termites and mold, kitHAUS produces modern modular builds that offer endless flexibility. Founded in 2005, the design and build firm is best known for their smaller builds that start from just 64 square feet—yet their modular system allows them to build larger projects as well.
