Top 7 Landscape Design Companies in Castle Rock, CO

Castle Rock's clay soil, elevation, and HOA rules make landscape design here a different job than it is thirty minutes north in Denver.

A design that ignores drainage on a sloped Douglas County lot, or skips the HOA submittal step, turns into a headache fast.

That’s why anyone building hardscape elements as part of a design should expect a look from the Douglas County Building Division before crews break ground.

The companies below all do real landscape design work in and around Castle Rock. If you want to see what a Castle Rock-specific design process looks like, our landscape design page walks through it.

1. Easy Green Landscaping

I’m Kyle Phung, and I started Easy Green Landscaping in 2012 because I wanted homeowners in the Denver Metro to get a landscape company that does what it says it will. We’re a design-build company, so the same team that draws your layout also builds it.

For Castle Rock specifically, that matters because of what’s under the surface. We design around the area’s clay soil, the elevation swings between neighborhoods, and the drainage patterns that show up after a hard rain.

Every design project comes with a fixed-price guarantee, so the number we quote is the number on your invoice, and installs carry workmanship warranties by service, from 2-year paver coverage to 15-year turf labor coverage. We also offer Wells Fargo 0% financing for 12 months.

We’ve designed and built more than 1,800 landscapes across the Denver Metro in 12+ years, with a 4.6 rating across 110+ Google reviews.

Easy Green Landscaping did a fantastic job on our backyard project! They were great to work with and very responsive to any requests we had. Peggy was so helpful throughout the process and the contractor Carlos did an amazing job bringing our vision to life. We could not be happier!

2. Rocky Mountain Precision Services

Rocky Mountain Precision Services, known locally as RMPS, has been headquartered in Castle Rock since Beau Wimberly started the company in 2016.

RMPS covers landscape design alongside concrete, hardscaping, sod, artificial turf, water features, and outdoor lighting, and the company markets itself as a landscape, hardscape, and irrigation specialist for Castle Rock and Douglas County specifically.

Excellent work from Beau and team, the end product was even better than we expected! We will definitely go back to them for future projects!

3. Phase One Landscapes

Phase One Landscapes has been building landscapes across the Denver Metro since 1988.

Phase One runs as a true design-build firm, meaning their landscape architects and construction crews work under the same roof rather than handing a design off to a subcontractor.

We couldn’t be happier with our experience working with Phase One Landscape! After receiving three bids for our major backyard renovation, Phase One stood out immediately, they were the only…

We worked with Rick, Justin, and Jose from Phase One to build an iron fence, front gate, brick pillars, and lighting for our front yard, and we couldn’t be happier with the result.

4. MG Landscaping

MG Landscaping, a Denver-based landscape design company, leans toward xeriscaping and rock conversions, which fits Castle Rock’s water-conscious HOA culture well.

Project sizes on record run from a few thousand dollars for a front yard refresh up to $15,000-plus for full backyard designs, giving Castle Rock homeowners a realistic middle-market option between smaller crews and larger design-build firms.

We have received so many compliments on our landscaping project! We were so lucky to find and hire MG Landscaping! His staff were on time and hard working! Efficient, attentive to detail and they cleaned up the site every day! MG Landscaping was easy to work with, listened to my ideas and designed a product exactly to my specifications!

5. YMS Landscaping

YMS Landscaping handles design through construction, including HOA-ready plans, retaining walls, paver patios, and putting greens, with each project starting from a site consultation rather than a template layout.

Their local, single-team structure shows up in how Castle Rock homeowners describe their HOA approval process specifically, a detail that matters in a town where most backyard projects need a design review before construction starts.

We couldn’t be happier with our backyard, thanks to Aaron and his amazing crew! Their flexible, collaborative approach during the estimating, design, and installation stages made the entire process enjoyable. The quality of their work is exceptional, and we’ve already recommended YMS to several neighbors!

John Bouchillon

Rated 5 out of 5

We have had multiple friends and family members use YMS. They came very highly recommended and they did not disappoint. Aaron and his crew did amazing work at a price much lower than competing groups. We would recommend them to anyone, will use them again for future projects.

6. Rock N Block - Turf N Hardscapes

Rock N Block has operated out of Castle Rock since 2017, and the company built its name on artificial turf before expanding into full hardscape and landscape design work, including patios, retaining walls, and putting greens.

Projects tend to run through a small, named team: Paul on the initial design and quote, Chris managing the build. The company is family-owned and serves Castle Rock alongside the wider Denver Metro.

Sarah Z.

Rated 5 out of 5

We recently hired Rock N Block for an artificial turf and rock installation project, and they did an outstanding job from start to finish. Billy, the designer, brought incredible creativity and attention to detail, helping us create a layout that looks both natural and beautiful. Chris, the project manager, kept everything running smoothly and on schedule.

Maria S.

Rated 5 out of 5

We had an amazing experience working with Chris at Rock N Block. He was incredibly knowledgeable and helped us develop a thoughtful plan for our challenging side yard, which was previously sloped and filled with rocks. Thanks to his expertise, the space is now beautifully constructed and fully functional.

7. American Design & Landscape

American Design & Landscape has been in business since 1967, making it one of the older landscape design firms serving the Castle Rock area.

The company runs a formal, multi-step design process, starting with a questionnaire and site consultation before any conceptual plan gets drawn. That structure makes this company a good fit for larger, more involved projects than a quick patio add-on.

Emily E.

Rated 5 out of 5

Not only did they complete the job in a timely manner but also ended up going above and beyond with leaving my back yard looking better than when they arrived on the first day.

Ashley D.

Rated 5 out of 5

We had quite a bit of landscaping done in our backyard and we were extremely impressed with American Design and Landscape. Mike did a great job putting together a plan as well as making great suggestions to us to help our maintenance be less. The project started right on time and the crew worked hard every day providing us with a beautiful new landscape.
