How Much Does It Cost To Build A Custom Home in Lethbridge?

How Much Does It Cost To Build A Custom Home?
If you're dreaming about building your perfect home in or around Lethbridge, one of the first questions you're probably asking is: "How much is this going to cost?"
Fair question, but not such a simple answer. At K2 Prairie
Builders, we believe in being transparent. The truth is, every custom home is different, and the cost depends on a mix of factors like design, size, location, materials, and even the weather.
For example, below are two sample floor plans both 525 square feet. With additional windows, doors, more exterior surface area, and a more complex foundation, the cost to build the house on the right will be more than the house on the left. If you phoned us and asked how much is your price per square foot and we told you $300 a square foot to build before any design or consultation is complete we would either be ripping you off on the simple design or losing our shirt on the more complex design.

Don’t worry we are going to break it down in plain English.

Understanding the Key Factors Affecting Custom Home Costs in Southern Alberta
Before you get a final price tag, here are the biggest things that influence what you’ll pay:
• Size of the home - More square footage means more materials and more labour.
• Design Complexity - Simple shapes are cheaper. Vaulted ceilings, extra corners, or custom features add cost.
• Finishes & Fixtures - Choosing luxury items like granite countertops or hardwood floors will bump your budget.
• Labour and Trades - Skilled trades cost more (and are worth every penny), even more so in high-demand seasons.
• Site Conditions - Is the land flat or sloped? Easy to access or remote? These all impact pricing.
• Utilities & Infrastructure - Need a septic system, well, or power hookups? That adds cost too.
Understanding Location Costs - Building in Lethbridge vs. Calgary or Edmonton
Average Cost to Build a Custom Home in Calgary
Calgary is a beautiful city, but building there isn't cheap. Expect to pay
anywhere up to $400 per square foot, depending on how custom your build is. In high-end areas or with luxury features, it can go up to $1,000+ per square foot.
What to Expect When Building a Custom Home in Edmonton
Surprising as it may seem Edmonton tends to be a bit more affordable. Costs range but tend to stick around the $300 per square foot, with more flexibility in land pricing and slightly lower trade rates.
Cost Considerations for Building in Rural Alberta
If you’re heading out into rural Alberta (like many of our K2 clients), you’ll often get more land for your money, but might need to budget for extra infrastructure like septic systems, wells, and access roads. That said, you’ll also have more freedom in design, fewer zoning headaches, and a unique setting.

Choosing the Right Builder for Your Custom Home
The best way to stay on track financially? Work with a builder who you respect and one that takes budgeting seriously.

• Features and accessories
You will get a more detailed estimate, so you can make informed decisions moving forward.

Now we get serious. By this stage, we're finalizing:

• Windows, doors, fixtures, and more
This leads to your fixed price quote, so you know exactly what you're getting and what it will cost.
