3301 Rider Trail South is a well-constructed, institutional-quality office building located in the heart of Earth City, one of the St. Louis region’s most established suburban office and employment corridors. The property offers a compelling blend of near-term value creation through lease-up and durable in-place cash flow anchored by a long-tenured credit tenant.

The building features approximately 27,560 square feet of current vacancy, concentrated on the second floor and divisible down to 5,000 square feet, providing a clear and executable leasing opportunity in a submarket historically favored by large corporate users. The vacant space benefits from efficient floor plates, excellent natural light, and proximity to multiple stair cores and elevators, allowing for flexible demising and efficient tenant layouts. Recent common-area improvements, including a renovated lobby, reinforce the building’s positioning and support competitive lease-up at market rents.
