Our Why

The homebuilding industry has a problem: too many houses are built to minimum standards — compromising health, durability, and efficiency. Families end up with homes that look good on day one, but underperform for decades.

At Costner Building Group, we believe you deserve better. That’s why we’re setting a new standard — where fine architecture meets sustainability, wellness, and performance.

We build purposefully:

• Guided by building science and proven best practices
• Designed in collaboration with our clients
• Crafted to be healthier, smarter, and more efficient

Our commitment is rooted in our core values:

• Healthy and Durable Homes.
• Respect for All People.
• A Continuous Pursuit of Excellence.

It’s all part of our mission:
Building Better So You Can Live Better
