Mighty Buildings

Mighty Buildings is an Oakland, California-based construction technology company, now operating as a LUMUS INC. brand, that has pioneered what it describes as the world's most complete 3D-printed exterior wall system for residential and commercial construction. The company manufactures two factory-produced wall system variants — MWS Residential, a load-bearing panel system requiring no separate superstructure, and MWS Commercial, designed for integration with structural frameworks — enabling complete wall assembly with only a four-person crew in as little as three days. The 3D-printed material has been rigorously tested for fire, wind, and seismic compliance, and the construction process is designed to meaningfully reduce labor costs and construction waste relative to traditional methods. Mighty Buildings is committed to achieving carbon neutrality across its operations and was named among Time Magazine's America's Top GreenTech Companies. The company has completed projects internationally, including work in Dubai, and has been featured in HUD's Innovative Housing Showcase.
