Hardscaping Built to Outlast the Front Range
Retaining walls, pavers, firepits, fencing, grading, and excavation — serving Lakewood and the greater Denver metro.
What We Do
Services We Offer
From retaining walls to full site excavation, we handle every stage of the outdoor build.

Retaining Walls
Retaining walls built from stone, brick, or block to stop slope erosion, add usable yard space, and hold back soil on sloped Front Range lots.

Concrete Pavers
Paver driveways, patios, and walkways in stone or brick patterns — durable, low-maintenance, and built to handle Colorado freeze-thaw cycles.

Outdoor Firepits
Custom outdoor firepits in concrete, stone, brick, metal, or glass, designed to fit the existing hardscape and layout of your yard.

Fencing
Wood, vinyl, chain link, and privacy/security fencing — new installation, replacement, and repair for residential and commercial properties.

Grading Services
Land leveling, slope correction, and drainage grading that prepares a site for construction, landscaping, or a new driveway and keeps water moving away from the foundation.

Excavation
Site prep, land clearing, trenching, and foundation excavation for residential and commercial projects across the Denver metro.

Tyler FitzGerald
We hired Collective Concepts for a retaining wall and fence project and it came out perfect! Cristian was incredibly responsive throughout the entire process. The work came out great and I'd highly recommend them to anyone looking for a reliable contractor.
David Daharsh
Christian and his crew did a stellar job! From start to finish, everything was top notch. Great communication, thorough explanations of what was going on: who would be there, how long the project would take, what material and why it was used. I was very nervous going into this because it's a major project. Christian addressed every concern that I had, from respecting my neighbors' plants and property to putting up a temporary fence so my dogs could run around safely for the week. Christian is very knowledgeable in his craft. We had about a week of weather delays, Christian kept me updated throughout. He bid the project about 6 weeks out and stuck to his quote. I felt like he was fair in his pricing with the scope of the project. Thank you, thank you, for a job well done!

Collective Concepts was great to work with on our huge project of replacing our 1960s era retaining walls! We weren't sure what we wanted to do, we just knew that we had to replace our walls. Christian was able to take our vague plans and create a great space that not only made the backyard safe but also added 30-40% additional outdoor space to our yard. The entire team was professional and the project was basically completed on schedule (we expanded the scope to adding fences last minute). Would highly recommend to anyone!

Collective Concepts did an outstanding job transforming both my front and backyard. They installed a modern paver garden bed in the front yard that completely elevated the curb appeal, and the paver patio in the backyard turned out even better than I imagined. The team was professional, detail-oriented, and easy to work with from start to finish. They took the time to understand what I wanted and executed it perfectly, with clean lines and a high-end finish. Everything was done on time, and the worksite was kept neat throughout the project. If you're looking for quality craftsmanship and a team that takes pride in their work, I highly recommend Collective Concepts.
Anthony Szado
Hired his team for a relatively small job and could not be happier. Added a small gravel driveway with a retaining wall to the side of our house. Highly recommend for great communication but most importantly quality of work.
Charles Bushman
Collective Concepts and Christian Gaytan were fabulous. They listened to our needs and recommended additional ideas that made the project wonderful. They constructed a new retaining wall and an expanded driveway. I would recommend them to anyone!
Hank Prey
Christian & his employees replaced an 85 ft long railroad ties retaining wall with large concrete blocks and it looks great! The project only took 3 days & they were on time every day. The price was very fair and I would hire them again.
Cullen Eckhart
Christian and his team were great! He listened to my needs and got me exactly what I had visioned for my retaining wall. His team was quick and efficient and left the area looking like it was before they started. I would recommend collective concepts to others with similar projects and will consider them for my future landscaping ideas!
Autumn
Had Collective Concepts put in a retaining wall in our backyard and they did a great job. I am very happy with the way the wall turned out and they are very reasonably priced too. Would definitely recommend!
