Expand Your Home Without Leaving the Life You’ve Built

Home Additions

Need More Space? Let’s Design the Perfect Addition to Your Home.

Whether you’re adding a second story, new room, or transforming a garage, AAA Home Improvements designs and builds custom home additions that blend seamlessly with your home and your lifestyle.

Custom Home Addition

Why Add Onto Your Home?

When moving isn’t the right option, a home addition gives you the space you need — without giving up the home you love. Additions allow you to stay in your neighborhood, increase your home’s value, and create personalized space that fits your evolving needs.

Great Reasons to Build a Home Addition:

A growing family and need more bedrooms

Aging parents moving in (or back in)

Need a home office, gym, or studio

Hosting long-term guests

Preparing for resale with added square footage

Want to increase natural light and improve the layout

A thoughtful home addition is one of the best investments you can make in your property — and your quality of life.

Let’s Talk About What’s Possible for Your Property

Every ADU starts with one conversation. We’ll help you understand what’s allowed, what’s possible, and what your next steps should be. There’s no obligation—just expert advice tailored to your situation.

Types of Home Additions We Specialize In

At AAA Home Improvements, we design and build high-end home additions that seamlessly blend with your existing structure — both aesthetically and structurally. Our design-build approach ensures the new space adds real value to your home and lifestyle while staying code-compliant and aligned with your long-term goals.

Second Story / Pop-Top Additions

A second story addition — often called a pop-top — adds an entire new level to your home, effectively doubling your living space without expanding your home’s footprint. These additions are ideal for urban areas with small lots or zoning limits and are perfect for growing families, multi-room suites, or full upstairs layouts.

Best for maximizing square footage on small lots and improving resale value.

Custom Room Additions

Room additions allow you to expand your home outward by adding a new bedroom, office, living room, or flex space to the main level. These projects are highly customizable and are perfect for homeowners who need more space but don’t want to move.

Best for extra bedrooms, home offices, or expanded living areas.

Garage Conversion Additions in Colorado

Transform your existing garage into a fully livable space with a garage conversion. These are excellent for building in-law suites, rental units, studios, or guest quarters — all without changing your home’s exterior footprint. A well-designed garage conversion offers a high ROI and a fast turnaround compared to new construction.

Best for creating ADU-style living without the cost of building new.

I cannot say enough great things about AAA. I've worked with them multiple times, and they have always been super professional. Toby and his team were always timely and responsive when I asked questions. I've referred several friends to AAA because they do great work. My family is considering building an ADU, and we plan on having AAA build it. I highly recommend AAA for any project, big or small. They are great!

We had a great experience working with Toby and his team building a second story addition on our 100+ year old bungalow. In fact our first project so well, we hired them again to remove some walls and open the kitchen to the main living areas of the home, and finally complete a full remodel of our kitchen including redesigning the entire layout, moving the gas lines, water lines, drain lines, new electrical, cabinets and even a new kitchen ceiling. I don't have any reason I would ever hire anyone else after two successful experiences with AAA Home Improvements.

AAA home improvements recently finished our basement. From the start to finish, the project went great. Starting with Bob on the design and working with Luke, Toby, JT, we were thoroughly impressed with each phase of the work. Eddie, Rich, Merrill, Robert, Carlos, Andre, Antonio were all experts in their trades and we couldn’t have asked for better crews on this project. The basement was completed as scheduled and It turned out perfect! We highly recommend this company and would use them again on any future projects we may have.

Our first experience with AAA Home Improvements was in about 2006 for a “refresh” of our kitchen (light remodel). Since then they have assisted us with restoration repairs when a pipe broke, flooding our finished basement, then a deck, then new roofing and finishing a basement when we moved in 2013. In 2019 we came back to AAA for a major kitchen remodel, followed by a complete renovation of our primary bathroom a couple years later. We kept returning to AAA Home Improvements time after time because of the blend of customer service and expertise that they provide. Toby is very solution oriented and reasonable to work with when problems arise. Years of history of working with a firm that is obviously concerned with getting the job done right led us to asking Toby if AAA Home Improvements would be willing to tackle a new build in a mountain community. Working with Luke and Toby on the design-build of the house was an enormous task with beautiful results! We will continue to recommend AAA Home Improvements and seek them out for future projects. (In photos: the brick wall and windows were previously a wall of cabinets, the cooktop was moved off the island, the soffit was removed and the arch entryway was enlarged.)
