Mighty Buildings, a California-based developer of prefabricated single-family housing and accessory dwelling units (ADUs), has announced that it has delivered a 3D-printed net-zero home.

The 2-bed 2-bath house is a part of a community of 40+ housing units expected to be developed in Southern California. According to the company, this is the world’s first net-zero energy home built using prefabricated 3D-printed panels.

Mighty Buildings also announced that it hopes to expand its B2B operations to enable housing developers to build sustainable housing communities at scale.

Analyst QuickTake: Mighty Buildings takes a different approach to developing houses by using 3D-printed prefabricated panels that are 60% made of recycled materials compared to other companies that use concrete to fully 3D print the house. This enables the company to offer more sustainable solutions than its competitors. The company has also partnered with materials technology company Fortera to develop a new type of cement that reduces carbon dioxide emissions by more than 60%. On a separate note, Mighty Buildings appointed a new COO and a CFO in April this year to support the company’s growth plans.
