WESTCHESTER, Calif. — As COVID-19 continues to keep many of us working remotely, more people are trying to create a permanent home office.  One option is an accessory dwelling unit, or ADU — also known as a guest house.

Earlier this year, Oakland-based Mighty Buildings started making them with a 3D printer.

"We developed a 3D printing technology that allows us to build and manufacture buildings faster and more efficiently than traditional construction," said Natalia Dobrynina, head of sales for Mighty Buildings.

Through September 22, the company is showcasing its 3D-printed ADU at a pop-up location near Westchester, which L.A.’s mayor has called a good neighborhood for ADUs because of the number of large backyards.

The company says its building plans are pre-approved for almost anywhere in California.

"Depending on your access to your site, we could use a crane to pick it up and drop it into your backyard," Dobrynina said.

Mighty Buildings is looking to disrupt the residential construction industry and make housing more affordable. Since the shell is manufactured using a 3D printer, the company says there is more flexibility in the design.

"We could print angles. We could 3D print corners, so there is less waste," said Dobrynina.

Mighty Buildings can currently print a 350 square foot ADU in less than 24 hours.

The small studio also features a murphy bed — once put away, the same space can become a common area.  The interiors come with countertops, cabinets, and all appliances, but there are additional costs to secure proper permits and utility hookups.  All in all, the company says an ADU could be ready to go in 4-6 months.

Since 2017, California has passed multiple bills making it easier for homeowners to build ADU on their property. Several laws took affect this past January, which streamlined the construction and approval process throughout the state.

"Everyone is stuck at home, and you realize you have that space in the backyard," said Dobrynina. "Why don’t you use that and create an office space or keep your family close?"

Mighty Buildings says the structure is made from a light, stone-composite material that is recyclable and more resilient than concrete. It’s also resistant to moisture, water, fire, and other environmental factors such as earthquakes.

"A lot of people don’t know what 3D printing is, so we’re here to educate homeowners and make sure they understand the process," Dobrynina said.

It's a process that could eventually change the game for homeowners, renters, and developers alike.
