Home Additions & ADUs
More Space. Thoughtfully Designed.
Whether your family is growing, you're working from home, welcoming aging parents, or creating space for guests, sometimes the best solution isn't moving—it's making the home you already love work better.
At True Design Build, we design and build custom home additions and accessory dwelling units (ADUs) throughout Evergreen, Golden, Conifer, Morrison, and Genesee, creating spaces that feel like they were always meant to be part of your home.
Built to Blend Seamlessly
Unlike interior remodels or new construction, additions and ADUs require your new space to connect flawlessly with what's already there.
From foundation work and structural engineering to roofing, siding, mechanical systems, and interior finishes, every detail must integrate with your existing home—both structurally and aesthetically.
Our integrated design-build process manages every phase, creating additions that look intentional, function beautifully, and feel like a natural extension of your home rather than an afterthought.
Projects may include:
Family room additions
Primary suite additions
Guest suites
Home offices
Second-story additions
Garage additions
Mudrooms and entry expansions
Detached studios
Accessory Dwelling Units (ADUs)
Guest houses
Aging-in-place living spaces
Multi-generational living
Planning Your Investment
Every addition and ADU is unique.
Because these projects involve excavation, foundations, structural engineering, roofing, mechanical systems, and complete construction, most home additions and ADUs begin around $250,000. Investment varies depending on size, site conditions, finish selections, and whether the structure is attached or detached.
We'll develop a detailed budget tailored specifically to your project before construction begins.
One Showroom. Endless Possibilities.
One of the biggest advantages of working with True Design Build is exclusive access to Evergreen Supply House, our co-located design showroom in Evergreen.
Instead of visiting multiple vendors across the Denver metro area, you'll make your selections in one thoughtfully curated space alongside our showroom team.
From cabinetry and flooring to tile, plumbing fixtures, lighting, hardware, and finishing details, every selection is made with your overall design, timeline, and budget in mind.
It's a more collaborative experience that saves time, reduces decision fatigue, and helps ensure every finish works beautifully together.

Built for Mountain Homes in Evergreen & the Foothills
Adding onto an existing home requires more than simply creating additional square footage.
Mountain lots often present unique challenges, including sloped sites, drainage considerations, snow loads, existing foundations, and complex permitting requirements.
Because we specialize in remodeling homes throughout Evergreen, Golden, Conifer, Morrison, and Genesee, we understand how to design additions that respect both your home's architecture and the surrounding landscape.
