Our Philosophy
At UBC, we are more than just builders. We are creative thinkers and Artisans—and we love what we do.
For us, simply building a large home does not invigorate or challenge our team. This is why we always encourage our clients to come to us with unique, ground-breaking ideas. This is where we excel!
As innovators and craftspeople, we love to push the possibilities to the limit. This includes using a vast array of materials and techniques.
We specialize in locating, outsourcing, and managing almost anything you can imagine, and we are constantly in search of new and interesting materials to use.
With access to any just about any type of material you can think of, from hardwood to exotic woods, you are only limited by your imagination!
Keeping on top of current trends and new technologies is also an important part of what we do. We are actively involved with implementing “Green” and “Leeds” building techniques and technologies.
