Twenty years ago, the modular housing industry walked around with quiet confidence. Sales representatives stood at home shows, builder meetings, and industry events and proudly explained that modular construction could deliver a home for as much as 20% less than conventional site-built construction.
At the time, many of them were right.
Factories were relatively lean, transportation was manageable, building codes were less complicated, overhead was lower, and most modular buyers were satisfied with homes that did not test the limits of architectural design or transportation logistics. Factories could build similar floor plans repeatedly, purchase materials in volume, and move modules through production without stopping for constant engineering revisions.
Today, that story has changed.
In many markets, modular construction comes in at approximately the same price as site-built construction. In some cases, it costs more. Developers, investors, builders, and prospective homeowners are now asking an obvious question: What happened to modular’s promised 20% savings?
Having watched this industry grow, stall, innovate, reinvent itself, and occasionally break its own heart, I believe the answer is relatively simple.
The world changed, and modular did not change fast enough.
The reasons behind the disappearance of that cost advantage, however, reveal something important about where modular construction is today and where it needs to go next.
