"First and foremost, we absolutely recommend Odyssey Construction Group LLC as a contractor for your home improvement project. The team’s transparency, willingness to work with us during the challenging time (COVID protocols, supply chain and material sourcing challenges) provided us with confidence that the team valued the quality and execution of the project as much as we did. Also critical is the fact that Jason, Paul, and the Odyssey team was on site every day and we never had to work with subcontractors – Jason handled all of the team’s schedules for us – never using subcontractors (safety is very important for Jason and our household). Pricing was also reasonable coming in below several vendors but the quality exceeded expectations. Finally the Odyssey team was very thorough with cleaning up each day, putting all tools and materials away and vacuuming before leaving each day which allowed us to remain safe during the project and was very different than previous contractors we have worked with. A few additional notes supporting why we are advocates for and we strongly recommend the Odyssey team: • Scope of the project – Our project included complete remodel of three bathrooms (tubs, sinks, tile, mirrors, lights, toilets, plumbing in each), and completely replaced floors of our main level (dining room, family room, kitchen). Additionally, the reasonable cost allowed us to expand the scope of the project to include updating the laundry room and fireplace! • Selection process – Odyssey provided an in-depth review of our project, provided examples of work along with recommendations from prior clients. From the beginning we felt comfortable with Jason and willingness to be transparent in pricing, insight into supply chain challenges we should be aware of and was very much a resource for questions we had even before we selected Odyssey as our contractor. Initially we also gathered estimates from five other vendors which included the same scope of our project. One never provided the outline of the work, two were ‘quotes’ with very little detail and one provided a good project management and time & materials plan but never responded to our follow-up questions and in the end was not transparent. Finally, the cost estimate was more reasonable than three of companies we received bids from but Jason’s understanding of our needs, experience in the projects we needed and constant communication was the primary reason for Odyssey winning our project."

"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!"

"Mark cleaned and stained my deck across the back of my house. We had to work out a day for the staining due the rain, snow and schedules. The deck turned out great, I am very pleased with the job Mark and Nathan did. Kathy from Arvada"

FAQs for addition to existing structure building service projects in Highlands Ranch, 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.
