103 Fortress Drive An exceptional opportunity to build on one of O'Fallon's most distinctive streets! Fortress Drive is an intimate luxury enclave known for its remarkable collection of custom homes, many showcasing French Country architecture, elegant porte-cocheres, and timeless architectural details. Each residence has its own unique character, creating a streetscape unlike any other in the area. Situated along this picturesque cul-de-sac, 103 Fortress Drive offers a rare opportunity to create a home worthy of its surroundings. The owners have combined two individual lots to create an expansive 0.64-acre home site. Its desirable rectangular configuration provides an ideal setting for a substantial custom residence with a broad, impressive street presence. The sewer easement has also been relocated to accommodate a larger building footprint, further enhancing the possibilities for future construction. The owners have gone a step further, working with an architect to develop custom home plans that are included with the sale. Whether bringing those plans to life or creating an entirely new design, this is an opportunity to build something truly special in one of O'Fallon's most striking residential settings.
