Custom Home Construction
Ground-Up Custom Home Construction Across the Denver Metro & Front Range
Build the home you’ve always envisioned. PrimeStone Construction Group is a licensed, structural engineer–owned custom home builder designing and constructing bespoke homes on your lot throughout Denver, Aurora, Lakewood, Boulder, and the greater Front Range. As a full design-build team, we manage architecture, structural engineering, permitting, and construction under one roof so your vision is built on a foundation of real engineering.
What is a custom home? A custom home is a one-of-a-kind residence designed specifically for your lot, lifestyle, and budget where you choose the layout, finishes, and every detail. It differs from a production or tract home, which repeats a builder’s existing floor plans. Custom building offers full personalization at a higher per-square-foot cost.
As a structural engineer–owned design–build firm, PrimeStone ensures that your custom home is not only beautifully designed but structurally sound, efficient, and fully compliant with building codes and local regulations throughout the Denver Metro Area and Colorado Front Range.
Our Custom Home Construction Services
PrimeStone provides a full suite of services for building custom homes that reflect your vision and deliver long-term performance:
As a structural engineer–owned company, every custom home we build benefits from internal engineering review and oversight — ensuring that structural systems, load paths, and safety elements are integrated from the earliest design stages.
How Much Does It Cost to Build a Custom Home in Colorado?
Building a custom home in Colorado in 2026 typically costs $300 to $450+ per square foot for the construction itself (excluding land). For a 2,000-square-foot custom home, that’s roughly $600,000 to $900,000+, with luxury finishes and mountain sites pushing higher. Land, soft costs, and site conditions add to the total.
Cost Component | What to Expect |
Construction (hard costs) | $300 – $450+ per sq ft |
Soft costs (design, permits, fees) | ~15–20% of budget in Denver |
Land | Varies widely by location |
Foundation (expansive soil) | Engineered / drilled-pier often a premium |
Custom vs. production home | Custom typically starts ~30% higher per sq ft |
Soft costs architecture, engineering, permits, HOA fees, and utility tap fees can consume 15–20% of your budget in Denver before construction starts. Every PrimeStone project includes a transparent, itemized budget up front.
How Long Does It Take to Build a Custom Home in Colorado?
A custom home in Colorado generally takes 6 to 14 months of active construction, but a complete project including design, engineering, and permitting often spans 12 to 24 months. Denver permitting can take up to 6 months for major residential reviews, and mountain jurisdictions with Design Review Boards take longer.
Phase | Typical Duration |
Design & 3D renderings | 4 – 8 weeks |
Structural engineering & documents | 3 – 6 weeks |
Permitting | 4 weeks – 6+ months |
Site work & foundation | 4 – 8 weeks |
Framing through finishes | 6 – 10 months |
We build a 10–15% contingency into every schedule and budget for Colorado-specific variables: weather, permit backlogs, and material lead times.
Custom Home vs. Production Home
Understanding the difference helps set expectations:
- Custom home: Designed from scratch for your lot and lifestyle. Full control over layout, systems, and finishes. Higher per-square-foot cost, longer timeline, completely personalized.
- Production / tract home: Built from a builder’s repeated floor plans in a development. Lower cost through economies of scale, but limited personalization.
PrimeStone specializes in true custom, ground-up homes where design and structure are engineered together from day one.
Our Custom Home Construction Process
We begin by listening to your goals, reviewing your site, and outlining the overall project scope, budget, and timeline.
Architectural design and structural engineering work together — creating plans that are beautiful, functional, and safety-driven.
We prepare and submit permit packages and coordinate with local building departments throughout the approval process.
From breaking ground to final finishes, we manage all phases of construction — keeping you informed with clear communication and scheduled updates.
Upon completion, we perform final inspections, complete punch-list items, and hand over your new custom home — ready for you to enjoy.
Colorado Custom Home Considerations
- Expansive soils: Front Range bentonite clay can heave foundations a geotechnical report and engineered (often drilled-pier) foundation are standard, not optional.
- Snow loads: Foothill and mountain sites require engineered snow-load capacity, raising roof and structural costs.
- Wildfire mitigation: Foothill and mountain lots increasingly require wildfire-hardened roofing, siding, and vents, plus defensible space.
- Permitting: Denver routes permits through Community Planning & Development; each municipality and mountain county has its own process and timeline.
- Altitude: Denver’s 5,280-ft elevation affects HVAC sizing and appliance specifications.
Permits & Code for Denver Custom Homes
Custom home construction requires full building, electrical, plumbing, and mechanical permits from Denver Community Planning & Development, and must meet adopted IBC/IRC 2021 codes with local amendments. Mountain jurisdictions add Design Review Board approval and wildfire requirements. As a structural engineer–owned firm, PrimeStone handles the geotechnical coordination, foundation engineering, and full permitting that make Colorado custom homes succeed.
