Prefabs We Love for 2021

By Camille LeFevre Home Features Editor
Dec 30, 2020

In the last decade, "prefab" has come to mean something quite different from the "manufactured" (otherwise known as trailer or mobile) homes of the past. Innovative architects and builders, even "starchitects," are now designing homes that can be prefabricated. These modular components can be built off-site in quality-controlled factories, then transported and constructed to the worksite in a matter of days.

Now, designers are also innovating prefab homes that are LEED, Passive House, or Net-Zero ready. Dodge Data & Analytics recently released a report entitled the Prefabrication and Modular Construction 2020 SmartMarket Report. It compiles information and insights from designers and architects, engineers and contractors already working within the prefab industry.

The report's authors write that prefab and modular construction are on the rise as the "industry seeks to improve safety, productivity, quality, cost, schedule, and sustainability performance." In particular, they add, "Construction sites are greener due to less waste being generated, and safer due to working with assemblies and modules produced off-site."

We agree and are equally enthused about prefab's potential. So much so that we'd like to share with you our favorite prefab manufacturers and models and why we're fans. Let's get started.

Plant Prefab 

The company, based in Rialto, CA, is the first custom modular and panelized home builder dedicated to sustainable building, materials, processes, and operations to achieve B Corporation certification. "As a socially responsible business, we've always been committed to wedding purpose and profit in our work," said Steve Glenn, founder, and CEO, in a press release.

They went on to say that they used the US Green Building Council's (USGBCs) LEED program for many years to secure third-party verification of their sustainability and performance. They consider B Lab to be an equivalent authority to measure the company's impact. They have an extremely comprehensive process and require that companies undergo verification every three years to maintain compliance.

Moreover, Plant Prefab believes "everyone deserves to live in a well-designed, beautiful, functional, and healthy home. We believe that you should never have to sacrifice form for function, aesthetics for efficiency, or style for sustainability." In partnership with architects, including Douglas W. Burdge, Brooks + Scarpa, Ray Kappe, and Geoffrey Warner at Alchemy Architects, Plant Prefab manufactures an array of modern sustainable prefabs, including Alchemy's lightHouse ADU (accessory dwelling unit).

In February 2020, the company debuted its own ADU, LivingHome 10, during Modernism Week in Palm Springs, CA., designed and built according to Plant Prefab's Z6 environmental health and sustainability framework. The company also offers larger homes through its LivingHome series, such as this one in rural Sonoma County. The home includes many sustainable features including:

  • High-performance heating and cooling systems
  • Energy Star appliances
  • Smart energy monitoring
  • LED lighting
  • Recycled high-performance insulation
  • Drywall with a high recycled content that's also mold-resistant and non-combustible
  • Low-flow water fixtures
  • Solar-ready or net-zero design

Ahead of the curve, Deltec won a US Department of Energy's DOE Housing Innovation Award in 2019. We featured one of Deltec's non-circular, net-zero panelized homes from the Renew Collection, which uses two-thirds less energy than a non-sustainable home. The homeowners upped the ante by powering their all-electric home with 18 solar panels.

Phoenix Haus 

We recently found out about Phoenix Haus, which has its own plant in Grand Junction, CO, where the company fabricates its net-zero, Passive House prefabs. That's quite a combination—and it works. On your next trip to the Rockies, you can experience one of the projects, H19, which is now on Airbnb.

After working through numerous iterations, Phoenix Haus came up with Passive House design and construction underscored by its certified Alpha building system. H19's super-insulated roof and wall panels, triple-pane doors and windows, heat pump, and 12 solar panels powering the electric house are quite the winning combination.

The sustainability key here is bamboo, which the company uses in its prefab construction instead of wood. Bamboo is a fast-growing natural material and provides options for building practices that save forests and natural resources. Bamboo, the company says, is a renewable resource that requires less energy and creates less pollution and waste. The tiny-home model, delightfully named Bonsai, is an excellent option for off-grid living.

Inspired by homes they enjoyed in Europe, the founders of Urbaneer designed three modular home models (with more to come). All three allow homeowners to live large in 300 to 1,800 square feet—due, in part, to innovative convertible spaces. The Huron has a hidden wall-bed system. The Grand is a one-bedroom, two-level home with a movable-track wall system that easily converts rooms from one use to another. The Tioga started it all with its European-inspired design and the patented room-transforming innovations for which Urbaneer is now known.
