McKelvey Homes Logo

Established in 1898, McKelvey Homes is St. Louis’ oldest residential builder. McKelvey started building in the City of St. Louis, building commercial, industrial, multi-family housing and single family residences, and was perceived even then as a pioneer and innovator. In fact, the company is even credited with building St. Louis’ first gas station. After building many homes in the St. Louis Area, Third Generation Owner, Bob McKelvey, was looking to find the perfect fit to take his company into the future. That perfect fit was St. Louis Homebuilding Industry Leader, Jim Brennan, President and Owner of McKelvey Homes. Jim is a former president of the Home Builder's Association and has more than 30-years of experience in the industry. He has continued to grow the company by seeking out the most appealing neighborhoods and offering a sophisticated portfolio of homes. He believes that "only quality endures."That is why we not only strive to meet the desires of our customers, but also to consistently exceed them with our extraordinary, century-old craftsmanship. We have taken that century of experience and continued to grow with it.Leading the way by consistently striving to improve in style and craftmanship, with state-of-the-art design, materials, and construction techniques that keep McKelvey Homes the very best you can buy.
