"Jason and his team are the best contractors I have worked with. I have lived in my home for 25 years and have remodeled and worked with other contractors so I have a pretty good foundation of how to plan my project, my vision and what I expect. Jason was incredibly helpful in the beginning when I showed him my plans and made suggestions that I would never have thought of. He actually picked out fixtures and the materials with me! His team is hardworking, professional and kind. I will be working with Jason in the future on additional updates and wish I found him before now because I had to ask him to re-do some of the work that was done by others. I highly recommend Odyssey Construction Group LLC!"

"Wow! I had the privilege of Bailey helping me with a project to build a pantry and I can’t express how impressed I am with his dedication and craftsmanship. He worked SO hard, all day long, and finished the entire thing in record time. All while having innovated ideas to make the project extremely functional and professional. His craftsmanship was outstanding and his work ethic was the cherry on top. I hope to work with him again soon."

"Jason and Alicia have not only been incredibly professional, but they have been patient, understanding and willing to work around our crazy schedules and 1 year old kiddo. Any questions we’ve had, they have gotten us an answer ASAP. We are looking forward to brining them back when we can build the extension on our home!!! HIGHLY RECOMMEND!!"

"Hired Denver Construction to renovate the main level of my house including the kitchen and the bathroom upstairs and they did such an awesome job. Trusted them in my home while I had to work and came back to a job well done on multiple occasions. Highly recommend this company. Will be hiring again sometime in the future. Thanks DC!"

"Can't recommend Rich highly enough. We hired him to finish out basement. bathroom, bedroom, living area. We were very novice in our knowledge of the process and Rich was very helpful throughout every step. He walked us through the space. Gave us suggestions when we asked, but also made it work when we wanted something done a certain way. He was responsive to every question we had. He made sure all of his people got the work done efficiently and, most importantly, stayed out of the way as I work from home. From a cost perspective, he made the project fit within our overall budget. He broke down what costs what, when and how much each payment would be, and there were zero additional costs at the end. If we ever move or need anything else done, Rich will absolutely be my one and only call."

"One word: Amazing! I have used DDB for multiple projects including design AND build of full basement, concrete patio/fence/main house access, master ensuite among many other small projects. DDB was on time, on budget and was amazing to communicate with along the way! Highly recommend."

"Gerald was great and very reasonably priced! We converted our den/office into a true third bedroom. He moved the door doorway, added a closet, redid carpet, paint, wall texture, and trim. You can’t even tell it wasn’t how the house originally was. It took him about a week. He was very respectful and used tarps to cover our carpet to minimize the mess. We have already re-hired him once to install a railing on our staircase. I highly recommend Gerald to come out and give you a quote for your next project!"

FAQs for addition to existing structure building service projects in Lone Tree, CO

You can typically raise your roof by four to eight feet, depending on your home's structure and roof design. The exact amount depends on factors like roof slope and framing support. Raising the roof creates additional interior space, enhances natural light, and increases your home's value. Consult a professional to determine the feasible height increase for your home.

Yes, you need a building permit to raise your roof. Obtaining a building permit ensures your project complies with local building codes and safety regulations. A professional contractor can assist with the permit and inspection process and ensure all legal and safety requirements are met. Your contractor will be familiar with building codes in your area, which can differ between cities or states.

While it's possible to raise a flat roof, it requires extensive structural modifications. Flat roofs lack the attic space and support structures of pitched roofs, so raising them involves significant engineering to ensure safety and durability. This process can be complex and costly, so professional assessment is essential before undertaking a project of this magnitude.
