My builder uses Houzz Pro to plan the timeline and give detailed estimates and daily updates with photos of progress, and provide invoices at pre-agreed key points in the build. This made the whole experience much more efficient and stress-free.

Featured Reviews for ADU Contractors Near Castle Rock

Nested. Design + Build
ADU Contractors Near Castle Rock
Average rating: 5 out of 5 starsJanuary 13, 2026
“We worked with Nested on a home renovation and addition that wrapped up last Thanksgiving, and it was honestly a dream experience. The team at Nested, especially Dave, Ariana, and Rebecca, was thoughtful, communicative, and consistently went above and beyond. They also connected us with Tim, our architect, who was fantastic to work with and played a huge role in bringing our vision to life. You always hear horror stories about construction projects going off the rails; we didn’t experience a single one. Every subcontractor who came through our home was professional, friendly, and respectful. Our neighbors even commented on how great the crews were. The project finished on time (maybe even early!), and we now have a beautiful home that feels perfectly aligned with how we want to live and grow as a family. We absolutely recommend Nested, and have already sent friends their way.”

“I’ve worked with Mark Hammer construction on several projects and referred him on numerous others. His professionalism of his staff and my experience was exceptional from start to finish. My referrals also agree with this same sentiment. A+ follow through and general contractor.”
Robert R. Larsen, Architect
ADU Contractors Near Castle Rock
Average rating: 5 out of 5 starsDecember 1, 2020
“We had a short deadline for an addition to our house and Robert not only finished his drawings quickly but also to absolute perfection. He ensured that every detail was mapped out and that it followed my vision exactly. The project unfortunately never reached completion due to an issue between me and my contractor but Robert was more than understanding about the situation and made sure that I had everything that I needed from him to complete the project in the future. I cannot recommend a more honest, hardworking, and stand up guy than Robert.”
