Denver's design-build contractor for home additions that feel seamless, not tacked on. From primary suite additions to second-story builds — we design, engineer, permit, and construct the entire project under one roof.
A home addition is one of the most complex renovation projects a homeowner can undertake. Unlike a remodel — where you're working within existing walls — an addition requires architectural design, structural engineering, zoning review, permitting, foundation work, and full exterior integration. Every discipline has to work in sequence, and one misstep early creates expensive problems late.
Most homeowners who've had a bad addition experience were working with a general contractor who outsourced design and engineering to third parties. That creates a broken telephone between what you envisioned, what was drawn, what was engineered, and what actually got built.
AAA Home Improvements operates as a true design-build firm. Our in-house team handles architecture, 3D renderings, structural coordination, permitting, and construction — all under one contract, one point of contact, and one guarantee. What we promise at the start is what you walk through at the end.
We've completed over 45 home additions across Denver and the Front Range. Our track record with the City & County of Denver building department, Jefferson County, and Arapahoe County means your permits move faster than they would with a contractor starting from scratch.
The most requested home addition in Denver. Add a dedicated primary bedroom with en-suite bath, walk-in closet, and — optionally — a private sitting area or covered deck. Transforms a dated home into a luxury retreat.
Also known as a 'pop-top'. We remove the roof, reinforce the main floor structure, and build an entire second level. Perfect for adding 2-3 bedrooms and a bathroom without sacrificing any yard space.
Expanding the rear of the home to create a massive, open-concept kitchen and living area. Often includes vaulted ceilings, large sliding glass doors, and seamless flow to outdoor living spaces.
Attached or detached garage additions, often with livable space above. Whether you need space for vehicles, a workshop, or a studio apartment (ADU) above, we design it to match your home.
Four-season rooms that bring the outdoors in. Fully conditioned space with expansive windows, allowing you to enjoy Colorado's sunshine year-round in total comfort.
Micro-additions (typically 2-10 feet) designed to enlarge a specific room—like adding space for a kitchen island, a larger bathroom vanity, or a walk-in closet—without foundation work.
An addition isn't just about building new walls—it's about seamlessly integrating new systems with your existing home. We manage the entire scope of work, ensuring structural integrity, code compliance, and aesthetic harmony.
We design the addition to match your home's existing rooflines, massing, and character, providing 3D walkthroughs before construction begins.
Our in-house engineer calculates load paths, foundation requirements, and structural tie-ins to ensure the addition is perfectly sound.
We navigate Denver's complex zoning laws, setback requirements, and bulk plane limits, securing all necessary permits on your behalf.
Whether it's a crawlspace, slab, or full basement foundation, we handle excavation, pouring, and tying into your existing foundation.
We assess your current electrical panel and HVAC system, upgrading or adding sub-panels and mini-splits as needed to support the new space.
We meticulously source brick, siding, roofing materials, and windows to ensure the exterior of the addition looks original to the home.
Most projects start with a single 30-minute call. No pressure, no obligation — just an honest conversation about what's possible for your home and your budget.
