 Building on mountain or rural land in Colorado often means facing long delays, high costs, and serious uncertainty with traditional well drilling.
Wells must often be drilled thousands of feet through solid granite, with no guarantee of reaching a reliable water source — and property owners are required to pay per foot, even if no water is found.
Worse yet, well drilling contractors often have waitlists stretching months or even years, delaying new home construction and occupancy.

At Tri-Lakes Contracting, we offer a smarter, faster solution:
Underground potable water storage systems that provide clean, reliable water — helping you meet county water supply requirements and move into your dream home without the risks, costs, and long delays of traditional well drilling.

At Tri-Lakes Contracting, we are the only active Monolithic Dome builders in Colorado offering complete ground-up construction. Each dome is built with a revolutionary process unlike any other:

• An inflatable airform shapes the structure
• Layers of closed-cell insulation deliver superior energy efficiency
• A reinforced grid of rebar provides unmatched strength
• A thick layer of shotcrete (sprayed concrete) seals the shell for maximum durability 

These homes can be built above ground or underground, giving you flexibility in design while delivering the same exceptional strength. The result is one of the safest, most resilient, and energy-efficient home designs available today — fireproof, disaster-resistant, and virtually maintenance-free, engineered to withstand Colorado’s harshest conditions from wildfires and high winds to heavy snow loads and freezing winters.

We provide construction drawings and customizable floor plans for domes of every shape, size, and budget. Whether you want a compact mountain retreat, a spacious family home, or a secure underground residence, a Monolithic Dome offers unparalleled protection, sustainability, and peace of mind — a home built for generations, not just decades.

At Tri-Lakes Contracting, we offer a complete gallery of pre-designed home plans — from cozy mountain cabins to expansive estates over 4,000 sq. ft.. Each plan is professionally designed for style, function, and Colorado’s rugged environment, giving you a proven starting point without the time and cost of designing from scratch.

Once you select a plan, our team facilitates engineering, approvals, and permitting, streamlining the process so you can move from vision to construction faster, easier, and more affordably.

Best of all, we are able to build homes starting in the $300,000 range — an exceptional value in today’s Colorado real estate market, where affordability and quality rarely go hand in hand.

With options for every budget and lifestyle, our pre-designed home plans make it simple to start building your Colorado dream home.
