BAX Engineering’s residential team combined creativity, precision, and persistence to bring a one-of-a-kind bed-and-breakfast to life in St. Charles County.

Spanning 337 acres in the heart of St. Charles County, Cottleville Trails stands as one of the largest and most defining residential developments in BAX Engineering’s portfolio. What began as a vision to create a connected community centered around lakes, walking paths, and open green space evolved into a coordinated effort involving thoughtful design, collaboration, and long-term planning.
