New Home Construction Contractor in Denver

Building a new home from the ground up is the most significant construction investment most people will ever make. At 303 Construction, we've been building custom homes and residential structures across the Denver metro since 2003. We understand Colorado's building codes, soil conditions, climate demands, and what it takes to build a home that lasts generations.

New home construction costs in Denver vary based on size, design complexity, and finish level. As of 2025, expect to pay $200–$400+ per square foot for quality new construction in the Denver metro. A well-built 2,500 sq ft custom home typically ranges from $500,000 to $1,000,000+ depending on lot, design, and finishes. We provide transparent, itemized estimates before breaking ground.

We manage the entire build process from start to finish: site preparation, foundation, framing, roofing, exterior finishes, rough-ins (plumbing, electrical, HVAC), insulation, drywall, interior finishes, cabinets, countertops, flooring, painting, fixtures, landscaping tie-ins, and final inspections. One general contractor managing every phase.

Denver's building code requirements are rigorous, and Colorado's soil conditions (expansive clay soils are common across the metro) demand specific foundation engineering. We've navigated these challenges on hundreds of projects and build every home to exceed minimum code requirements.
