About Us

Honesty Upfront

The building process is complex. For this reason, we take a straightforward and honest approach to communicating with our clients to ensure the best outcome for everyone. If we’re not the right fit for the job, we will be happy to direct you to the right builder for your needs.

Our Mission

The Garrison mission is to strive for complete customer satisfaction by fulfilling every task with the highest level of professionalism, integrity, and quality construction.

Here’s what drives us.

Our Core Values

1. We Succeed When Our Clients And Partners Succeed

What drives us most is knowing we’ve done an excellent job. Our clients’ happiness gives us satisfaction in our work, which means everything to us.

2. We Are A Good Neighbour In Our Communities

We build our own homes, and we’ve carefully vetted the trades we’ve chosen to work closely with. Extremely conscientious of the communities we serve, we keep our sites safe and clean.

3. We Demonstrate Integrity By Doing What We Say We Will Do

Open communication, honesty and accountability are at the forefront of everything we do.

4. We Are Committed To The Value Of Our Work 

Demonstrating reliability, discipline and diligence allows us to produce quality semi-custom homes our clients can be proud of.

5. We Seek A Respectful and Welcoming Environment

Through our behaviour, we show empathy and care for others, acknowledging that our decisions impact those around us.
