Commercial Experience

KBS Builders is not a single unit modular builder. We have worked with commercial clients from day one and understand the pressures of a commercial job.

KBS offers precision modular construction for commercial projects

Production Capacity

Unlike other providers, KBS has multiple factories and lines, so we are able to produce a much higher volume of units. This translates into faster completion times.

KBS Builders offers custom engineering for modular projects


KBS Builders can take your requirements and design a product around those needs. With KBS you are not locked into stock plans or blueprints.

Build Smarter with Prefabricated Panels

KBS now offers our high-performance prefabricated wall and roof systems as individual components. All components are engineered with virtual models and fabricated in a controlled work environment, resulting in a durable, energy-efficient structure.

Building residential and commercial projects with pre-assembled panels allow you to move faster and with more confidence over traditional building methods.
