Built in 1883 as one of only two brick homes in a young Rapid City, 1204 Mt. Rushmore Road carries a rare and storied past: its brick walls were raised by pioneer contractor and brickmaker Louis Volin using material from his own Black Hills brickyard for original owner Eli Fenstermaker, then passed through the hands of banker and two-term Rapid City mayor James Halley and prominent cattle baron Maurice Keliher before returning full circle to Volin himself in 1907. That history has been matched by a thoughtful modern transformation, with the original stone foundation and layered brick construction preserved, while the roof, gutters, electrical, and plumbing were updated, and hardwood floors, custom trim, updated bathrooms, and a granite-countertop kitchenette were added throughout. The building offers 1,440 total square feet, including 1,056square feet of main-level office and meeting space, plus a versatile upstairs area with its own full bath, natural gas forced-air heat, central cooling, and a partial basement. Zoned Office Commercial and situated on a high-visibility stretch of Mt. Rushmore Road with an estimated 24,498 vehicles passing daily, the property offers off-street parking. Historic due to its age and significance but not currently listed on the National Register or within the local historic district, this is a rare chance to own a genuine piece of Rapid City's founding history with all the functionality today's business demands.
