This confluence of challenges has resulted in over a decade of underproduction of new homes.

Experts estimate that the U.S. needs an additional 3.4 to 6.4 million homes annually to meet demand. Did You Know? According to a report by the National Association of Realtors,housing starts hit a 10-month low in April 2024,further exacerbating the supply shortage.

Federal Policy: A key Enabler

While technologies like 3D concrete printing and AI hold immense promise, federal policy support is crucial to overcoming systemic barriers to innovation. This support can de-risk innovation for builders and encourage broader adoption of new methods.

“Our policy dilemma is that the nation is not reaping economic and social returns from innovation when the industry is not innovating as much as possible,” said McCoy. “We tend to think of housing as an economic indicator, while we need to see housing innovation as an economic driver.”

Virginia’s Innovative Approach

Virginia state agencies and local governments are actively working to reduce barriers to innovation.These efforts include zoning and regulatory reforms, as well as new funding options that incentivize the adoption of cutting-edge housing technologies.

For example, a Community Innovation Grant from the Virginia Housing Development Authority supported a Virginia Tech research team in using 3D concrete printing to construct affordable housing units. Pro Tip: Explore local grant programs and incentives if you’re a builder looking to adopt new construction technologies.

Ten more 3D-printed homes are planned, with the potential for many more, demonstrating the scalability of this approach.

Workforce-Centered Solutions

These new technologies are not about eliminating jobs; rather, they are reshaping them. Augmented reality tools can definitely help framers work faster and more accurately,while electricians can gain enhanced visibility into walls and equipment.

Virginia Tech is preparing its students for these changes by training them on state-of-the-art building construction technologies. This ensures that the future workforce is equipped to leverage these advancements.

The Coalition for Smart Construction at Virginia Tech is pushing the boundaries of engineering with backing from industry and government partners.

Overcoming Industry Hesitancy

Mobilizing the traditionally risk-averse home building industry to embrace large-scale changes will require significant effort.This is why advocating for federal policy and financial support for construction technology is essential.

“The goal isn’t to automate people out of housing,” McCoy told legislators, “but to build a better industry around them.”
