Who we are
Built on Integrity. Licensed to Build.
Green Castle Environmental is a licensed Alberta home builder focused on high-performance, sustainable residential construction in Southern Alberta.
Why We Started Green Castle
Green Castle Environmental was founded on a straightforward belief: Southern Alberta deserves homes that are actually built for Southern Alberta. Not homes designed for a milder climate and adapted as an afterthought — homes engineered from the ground up for the cold, the wind, the sun, and the temperature swings that define life on the prairies.
We started with a single question: what would a truly high-performance home look like if you designed it specifically for this climate, with responsible materials, and without cutting corners on the building envelope? The Timberline Bungalow is our answer.
Every home we build is a reflection of that commitment — to our clients, to the communities we build in, and to the land itself.
Honesty First
We tell you what a home will actually cost, how it will actually perform, and what the trade-offs are. No surprises after the contract is signed.
Science Over Trend
Building decisions are made on building science — thermal performance, air sealing, moisture management — not on what looks good in a brochure.
Built for Longevity
We specify materials and systems that will still be performing well in 50 years. A home is the largest purchase most people ever make — it should last.
Rooted in Alberta
We live and work in Southern Alberta. We source locally where we can, we hire locally, and we build for the community we're part of.
Licensed and Accountable
Green Castle Environmental is a licensed Alberta home builder registered under the Alberta New Home Buyer Protection Act. Every home we build carries full New Home Warranty Program coverage — protecting your investment from day one.
