Here we showcase Boulder, Colorado’s top five Exterior Design and Landscaping experts! Discover the finest local designers as we highlight their exceptional quality, creativity, and innovative approach that makes them stand out. Let’s dive into the best of exterior design and landscaping excellence in Boulder.

For four decades, we’ve been transforming backyards into life-enhancing outdoor sanctuaries—seamlessly blending the indoors with the outdoors. Whether it’s a cozy patio or a fully equipped year-round living space, each project is thoughtfully designed and crafted to feel like an original part of your home. Discover the added value and lifelong returns that outdoor living can bring.
As a design-build team specializing in outdoor living, we’ve been trailblazers on the Front Range since 1985. We treat every project—regardless of size—as a unique opportunity to create a personal masterpiece. Our goal is to make your new space feel like it was always meant to be there.
Our greatest strength? Our team. We attract and keep top talent with competitive salaries, excellent PTO, 401k matching, health benefits, and performance bonuses.
And yes—we had a blast being featured on DIY Network’s Mega Decks for three amazing seasons! Though the cameras have stopped rolling, our passion for creating remarkable outdoor transformations across Colorado is as strong as ever.
Our Design Consultations start with a 5-10 minute phone call with one of our designers, where we discuss the general scope of the project. If we sound like a good fit, we will schedule an on-site design consultation. This is where design ideas and budgets are carefully considered. These appointments can last 1-2 hours and are the foundation of the entire project in regard to budget, design, and expectations.
Your designer will meet you at your home or at one of our three showrooms to present your 3D design and show you materials and features. We have cutting-edge technology that allows you to see the design in very realistic 3D pictures, video, or virtual reality. The presentation will take away all the visualization barriers and make it easy for the client to see how the outdoor space will look when finished. This is also when we can present the build proposal so the client can see the total budget as well as how specific features add to it.
Our team will bring your design to life! We are turnkey. Our office staff will handle the framing plans, engineering, permits, material take-off, and HOA. We will manage all the team members who touch your project. You will have a project manager committed to communicating with you throughout, so you understand the timelines and what is happening.
