Founded in 2004, X3 LLC is a design-oriented construction management and development company that focuses on reviving the residential and commercial metropolitan core of the St. Louis, Missouri area with a modern flair.

St. Louis has a rich history of impressive architecture and craftsmen from the turn of the century, but has also seen a loss of that tradition over the last 20-30 years. Many great buildings have been lost over time and, unfortunately, many inferior structures have been erected in their places. X3 has a strong commitment to rebuilding these neighborhoods and communities with timeless building materials that will hold up to the rigors of future renovations.
