In just four years, the Silicon Valley start-up Katerra has grown from a sizable construction firm to one of the industry's biggest disrupters. Now, with support from one of the tech industry's biggest investors, the California-based construction company has announced plans for another investment round that will have it valued at more than $4 billion.

SoftBank, the billion dollar venture capital firm helping to bankroll companies such as Uber, WeWork and the indoor farming start-up Plenty, is expected to lead the $700 million round of financing for Katerra. This comes less than a year after the Japanese holdings company invested a prior $865 million into the company. 

In Katerra, SoftBank is backing a revolutionary approach that promises to redefine the $12 trillion construction industry. The company's aim is to make the building construction process cheaper and more efficient and while Katerra is not unique in this quest, it is remarkable for its end-to-end design-build process which promises to handle everything from the architectural design of a building to off-site construction and installation. 

Over the course of its aggressive growth, the company has built up a factory in Phoenix that manufactures wall panels, cabinets and countertops; a facility in Spokane, Washington churning out mass timber; and has acquired the architecture firms Michael Green Architecture and Lord Aeck Sargent. 

A one-stop shop for buildings, the company is hoping to consolidate a messy system by approaching building construction more like the auto industry, which is known for practicing a high degree of vertical integration. 

Already, the company is set to deliver $3.7 billion in new projects with a team of nearly 4,000 employees. The additional funding will help prepare the company to build out a new facility in Tracy, California and produce an additional 12,500 multifamily units per year.
