What’s Stopping Your Home From Truly Working for You?

Whether your home is a classic mid-century ranch near Olde Town or a newer build in Candelas, the right addition can transform your space to fit your lifestyle — without sacrificing the character of your home. At AAA Home Improvements, we offer a variety of professionally designed and engineered additions tailored to the unique needs of Arvada homeowners. Each project is fully customized based on your goals, lot size, budget, and zoning regulations.

Second Story / Pop-Top Additions

Make the most of your urban lot by adding a second story. Pop-tops are especially popular in neighborhoods like Washington Park, Platt Park, and Berkeley — where land is tight but square footage is a must. We ensure structural integrity, architectural continuity, and smooth transitions between old and new space.

How We Navigate Denver's Zoning & Permitting:

Home additions in Denver must comply with city building codes, zoning requirements, and—in some cases—historic district overlays. But don’t worry, we take care of it all.

We’re experienced in:

  • Conducting zoning reviews for setbacks, height limits, and allowable square footage

  • Navigating Historic Preservation and Landmark district regulations

  • Managing all City and County of Denver permit applications

  • Coordinating inspections and ensuring full code compliance

Unlike many general contractors who leave you to figure out the red tape, we handle everything in-house. Our process is designed to make your life easier—every step of the way.

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.)
