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.

Deltec

Well-known for its round-house prefabs, Deltec works with clients to achieve the level of sustainability they're seeking. Whether homeowners are simply seeking energy efficiency or aspiring to net-zero, the company designs homes that seamlessly connect the indoors and outdoor landscape. The prefabs are fabricated in a factory powered by 100% renewable energy. Based in Asheville, NC, the company also has a recycle and reuse program that diverts more than 80% of waste away from landfills.

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.

Bamboo Living

Based in Pahoa, HI, this fascinating prefab company creates the "only internationally certified, permit-ready bamboo homes and buildings in the world," according to Bamboo Living's website. Durable, low-maintenance, pest- and insect-resistant, and able to withstand hurricanes with winds more than 200 mph, these prefabs are built for resilience.

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.
