Add space, rework your layout, or build from the ground up with a team that manages the entire construction process.
Additions and new construction projects often start with a practical goal: more space, a better layout, or a structure that doesn’t exist yet. Whether you’re expanding an existing home or building from the ground up, early planning plays a major role in how the space functions, how systems come together, and how smoothly the project moves forward.
We work with homeowners and property owners across Central Illinois to plan and build additions and new structures with the full process in mind. From layout and structural considerations to trade coordination and construction, our team manages each phase to keep decisions aligned with how the space will be used, now and in the future. With in-house trades and coordinated project management, we reduce handoffs and scheduling gaps that slow projects down.

Examples of additions and ground-up builds completed across Central Illinois.
Projects designed for how people actually live and work across homes, properties, and commercial spaces in Central Illinois.
Add space for growing families, changing needs, or better flow. Projects are planned to connect cleanly with the existing structure.
Expand kitchens, living rooms, or primary suites that no longer work. Layout, structure, and systems are considered together.
Add living space without expanding the home’s footprint. This option is common when lot size or zoning limits outward growth.
Build attached or detached garages for vehicles, storage, or workspace. Designs can include additional storage or finished space above.
Build a home designed around your lifestyle and priorities. Floor plans, materials, and layout are customized from the start.
Construct a new home on your lot with modern systems and layouts. Ideal for homeowners starting fresh or developing property.
Create flexible structures for storage, equipment, or hobbies. Common across rural and semi-rural Central Illinois properties.
Build workshops, machine sheds, or utility buildings sized for real use. Power needs, access, and durability are planned early.
Construct offices, light commercial buildings, or expansions. Projects are planned around use, code requirements, and long-term function.

They were so pleasant and friendly and really cleaned up nicely afterward. All the CU Under Construction people are fabulous!!!Posted on Kay PTrustindex verifies that the original source of the review is Google. We recently bought a home that was built in the 1970s. The kitchen was in desperate need of an update. We decided to hire CU Under Construction immediately after our first meeting with the sales rep, Chad. There was no doubt this was a top notch company. Chad was phenomenal throughout the process. Our kitchen update was extensive involving removal of an external wall, a half bath, laundry room, dining room and a 2-room large kitchen. They also removed all of our baseboard heaters and installed a new furnace. Jarrod was assigned as our project manager. He was truly amazing. He communicated with us frequently throughout the project and always responded to us promptly. Given the magnitude of this project, there were many moving parts. Jarrod never missed a beat. He always knew the status of the project. Everyone involved in this project was extremely competent and professional. We didn’t encounter one issue through the process. It was truly seamless. Emily, the project assistant, worked with me one on one to pick out everything including the flooring, countertops all the way down to the handles on the doors. She was truly a gem. There were several selections I had to make that caused me great anxiety. With her extensive experience in this field, she was very familiar with all the various product options and would talk me through my selections quickly minimizing my stress. I honestly cannot say enough about Shaun and Corbin, the carpenters. These two guys were so easy to work with and extremely knowledgeable. Their carpentry skills are outstanding. There were several times throughout the project that they were faced with complicated issues that required the skill set of a craftsman. Without any hesitation, these two would put their heads together and figure it out. We couldn’t have been more impressed. Greg, the electrician, was also simply incredible. He was very personable, professional and competent. He was always thinking 10 steps ahead when working on our project. We really enjoyed working with him. Lastly, there are so many folks at CU Under Construction that made our kitchen remodel a success and too many to mention. Everyone we worked with was knowledgeable, professional and respectful. Our kitchen is more beautiful than we could have ever imagined. If you’re looking for a construction company to do a project for you, give them a call. You will not be disappointed. Thank you to everyone at CU Under Construction—we LOVE our new kitchen.Posted on Faye cTrustindex verifies that the original source of the review is Google. We have been totally satisfied with all the communication from the estimate to the completed job from CU construction.. From the first meeting to the new roof, It has been a pleasure. Mark was on top of things to check on the progress of the workers. They were all great! They were definitely great workers that put all their effort into a good job. Our new roof is wonderful!Posted on Mike WTrustindex verifies that the original source of the review is Google. Three years ago, we had C-U Under Construction remediate a major insurance claim on our condo. The unit above ours had a burst washing machine hose that steadily pumped water down to our unit. It was raining inside! C-U worked seamlessly with our insurance company and the other unit involved. Excellent work! Very professional! Fast-forward to today. We sold the condo and the buyers is asking us to look at an area of concern. Mike Randolph was out there the next day and quickly provided a professional assessment using the latest technology. To top it off, C-U did not charge for the assessment. Top notch! Recommendation: Hire this group for your next project!Posted on Janet CTrustindex verifies that the original source of the review is Google. CU Under Construction contributed greatly to a project at our office building in Savoy. The quality of work was excellent, and they shifted schedules around so that the work could get done within our timeframe. The painters were precise and professional. The carpet installers were great at their craft and willing to work over the weekend to get ahead on the project. The project manager was very responsive to my needs and questions. I would highly recommend working with CU Under Construction!Posted on Henry wTrustindex verifies that the original source of the review is Google.
