Our Mission


Our mission is to offer our customers a superior construction experience through our technological prowess, market-specific expertise, and highly trained staff. We aim to add significant value to every project and partner in our customers’ success.


Many project owners can probably relate to having a contentions relationship with their contractor by the end of the project. Many of ours become our friends.


We’re business people too. We understand the limitations of budgets and the importance of timeframes. Entering into a contract with us guarantees a fiduciary relationship protecting our customers’ investments and provides for expert opinions in achieving the best possible outcome.

Happy Clients

Tim and the team at Eagan Design + Build were a pleasure to work with from start to finish. We faced numerous difficulties in our project, not the least of which was a lengthy permitting delay. Despite these challenges, they worked extra hard to get us open on time! I really appreciate their hard work and attention to detail. I would highly recommend Eagan Design + Build for any of your building needs!

Jonathan Pollock


I have had the privilege of working with the Eagan team on several projects over the past three years.  Every project validated my decision to choose Eagan.  Not only are they great at all the upfront consultation to ensure that they understand my needs and have accurately quoted based on those needs, but the finished product is everything I expected and more every time! What sets Eagan apart is that they work hand in hand with the architect and design team to fully understand your needs upfront to ensure there are no surprises on the back end with the finished product or the costs.

Melinda Vedder


Can’t say enough about how much we have loved working with this group for over 15+ years. The quality of the furniture is excellent and the customer service provided before, during, and after installations is why we continue to use this group for any furniture, design or builds needs in our offices. The ability to customize any design for architectural or construction needs is why they are hands down the best in the business.

I just wanted to thank you for your hard work and dedication in making sure that our vision for our new headquarters was realized. I appreciate the effort you put into listening and discussing our needs up front before finalizing the plan and your attention to detail throughout construction.


Doug Brooks


Just wanted to say thank you for your effort and the effort of your subcontractors in our project for the regional training center. The craftsmanship was good and you met a very tough schedule. Should the opportunity come in the future, we would not hesitate to work with you.

Our Company, Auto Assure, contracted with Eagan Building Group to remodel our offices in O’Fallon, MO.  They provided a full scope of work in a timely and professional manner.  The quality of the craftsmanship as well as the responsiveness to our needs was excellent.  Eagan communicated with us clearly and stayed within estimated costs.  We look forward to utilizing their service in the future.
