Custom Home Construction
Custom home construction for the Colorado high country
Senior-led, ground-up custom homes built for mountain sites — from site development and foundations through final finishes and certificate of occupancy.
A mountain custom home lives or dies on the site work under it — and that's exactly the part we do ourselves.
Tri-Lakes Contracting is a licensed and insured general contractor delivering ground-up custom homes and property development across Colorado's mountain regions. We build for durability, performance, and long-term value in high-altitude environments — and we manage the whole thing, from early planning and permitting through final inspection and certificate of occupancy, coordinating closely with engineers, architects, and trusted trade partners.
What sets a Tri-Lakes build apart is that the hardest part of a mountain home — the site under it — is handled in-house. Because we run our own excavation, septic, and water-storage crews, the access road, the foundation, the wastewater, and the water aren't subbed out to three vendors and hoped for — they're built by the same team that frames and finishes the house.
From raw land through a completed home, you get senior-led execution, clear communication at every phase, and a house built to perform through Colorado's snow load, freeze-thaw, and severe-weather demands.
Complete project delivery

Build-ready designs or full custom architectural coordination, budgeting, constructability review, and permitting support — a buildable, permitted plan from a lot and a vision.
Permitting & documentation
Building, septic, grading, driveway, and utility permits managed for compliance and schedule continuity, with the county and health department.
Site development & utilities
Excavation, grading, access roads, utility trenching, and onsite wastewater — the mountain site work, by our own crews.
Foundations & structural
Excavation and concrete for basements, crawl spaces, garages, retaining walls, and structural flatwork built for the ground and the load.

Questions
How much does a custom home cost in the Colorado mountains?
It varies widely with site, size, and finish — mountain site development (access, foundations, septic, water) is the swing factor. We scope it during feasibility so you have a real budget, not a guess.
Do you do design-build?
Yes — we can take you from raw lot and concept through permitting and construction, or build from plans you already have.
Can you build on a steep or remote lot?
That's our normal. High-altitude, difficult-access, and remote terrain is what we're set up for.
Do you handle septic, water, and the driveway too?
Yes — all in-house, which is a major advantage on a mountain build where those are the hardest parts.
