Custom Outdoor Spaces Design & Build in Boulder

"Green Mountain Boys are amazing. Peter is very knowledgeable and we learned a lot about our plants from him. This was a big job and they got through it in 3 days. It looks wonderful and we plan on them doing the ongoing maintenance as well. I would recommend them to anyone, everything was done so efficiently."

"Wonderful experiences with Peter and the Green Mountain team. Extremely reliable, professional, and hard working crew that we've worked with for a few years now. Highly recommended!"

"We recently collaborated with Green Mountain Boys on a landscape project they brought us in on, and it was a great experience. Their team was organized, communicative, and focused on delivering a high-quality result. We’re currently working through design ideas on a couple more projects together and look forward to continuing the partnership."

"Green Mountain Boys built our hardscape patio and the whole experience felt sharp from day one. The design process was collaborative and thoughtful — they walked the space with us, offered strong ideas on layout and materials, and made us feel confident without ever being pushy. The crew works hard and takes real pride in their craft. The patio base is rock solid, the cuts are clean, and the finished space feels intentional and high-end. Great attitude, great communication, and a result we’re genuinely proud to show off."

"We had a great experience with Green Mountain Boys. Peter came out, walked the property with us, and actually listened. He asked how we use the yard, what we cared about, and where we wanted to invest versus save. He offered suggestions and we were impressed with his plant knowledge and creative ideas. The design process was simple and clear. No pressure, no upselling — just honest conversations and solid ideas. Once the job started, the crew showed up when they said they would and kept the site clean. The finished product looks sharp and feels built the right way. You can tell they care about doing it right, not just getting it done."
