With over 20 years of experience in the building industry, David Bundellu founded Keystone Building Company with a simple goal: to deliver high-quality builds with honesty, reliability, and exceptional workmanship.

Backed by a small, skilled team and a network of trusted trades, we take pride in bringing each client’s vision to life. From bespoke renovations to new custom builds, we believe great building is about more than just the final result—it’s about the journey, the relationships, and the care taken at every step.
