Expert Home Additions in Jefferson County, CO

Home additions give Jefferson County homeowners a way to gain square footage without leaving a neighborhood they already know. Dingle Development and Construction handles the full scope of addition work: room additions, second-story builds, garage conversions, and expanded living areas. We manage design coordination, structural work, and all trade scopes under one roof so nothing falls through the cracks. Jefferson County requires building permits and plan review for all residential additions, and our team handles that process from document prep through final inspection. Many homes in the county were built decades ago and were not designed for today's family sizes or work-from-home needs. Adding on is often a smarter move than buying in a tight market. If your current home has the lot space and the bones, an addition can deliver the rooms you need while keeping your property rooted in Jefferson County. Call Dingle Development and Construction to talk through your project.

Mark remodeled my main bathroom and did such a wonderful job! He was reliable and very pleasant to work with and he got the job done quickly. He paid great attention to detail and was really able to bring my vision to life. My bathroom was very outdated before, and now it’s absolutely beautiful! I couldn’t be happier with the work Dingle Development did. I am looking forward to working with Mark again on my guest bathroom and future projects!

Mark and his team did a great job on my garage and sports storage shed. It was a job too big for me, but he was able to take care of everything. He made my vision come to life and I’ll definitely be using him on our room addition we’re planning now. The storage shed has all of our sports gear organized, with plenty of room to expand our athletic and exercise equipment.

Huge thanks to Mark! He helped us build our dream nursery for our baby girl and it was everything we wanted plus more! I was very pleased and grateful about the whole process. As first time soon to be parents, we were juggling so many things at once and he made everything worry free for us! I highly recommend Mark if you are looking for someone to help create a special space in your home!

I highly recommend Dingle Development. They did an amazing job remodeling the second story of my home, including two bedrooms and a bathroom. They handled everything and the transformation looks amazing! Their team was professional, dependable and communicated throughout the entire process. They made it stress free and everything was done right and with my vision in mind. I definitely appreciate the hard work and commitment they showed.

Laurie Shield Google review · September 2026

Mark was an amazing contractor to work with from start to finish! We hired him to do our bathroom remodel and he was very communicative throughout the process. He was also very helpful when it came to brainstorming ideas and helping us get exactly what we wanted done for the bathroom. It’s rare to find an honest and professional contractor these days so highly recommend!!!
