Whether Your Addition Is Large or Small — We Design to Your Budget

At Action Builders, we design your new addition—of any size—to fit your financial needs. We diligently document every detail of your home and provide accurate cost estimates for the design that matches your family’s lifestyle—while being a true expansion of your current home. We can handle the small 15×15 one-room addition off the back of a home, or do a complete tear down to the foundation and rebuild. Every home addition comes with a 5-year workmanship warranty, giving homeowners peace of mind.

We Listen to Your Vision and Pinpoint a Cost Range for Your Addition

Our initial on-site consultation allows us to see your house and listen to your vision for the space so we can offer a “ballpark initial cost” for your addition. The cost range for your project is based on our initial discussion in your home. We then fine tune the details before the budget is set.

We Focus Strategically on Your Top Priorities When Assigning Funds

We want to know your top priorities so we can design your addition best and include as many of your desires and needs as possible without breaking the bank. The beauty of our process is that we allocate your funds to the elements of your project that will get you the most “bang for your buck.”

We Present Options and Put Exact Costs to Your Project

Once we outline your new addition on paper, we detail a variety of options for you to choose from based on different sizes, finishes, and any other elements that drive the overall cost of your project. Every addition is different, so getting the details written up is a vital step in putting exact costs to your project. With over 30 years in the industry, we help homeowners expand their space with beautiful, functional home additions—big and small. And we’re ready to help you make your dreams a reality.
