Builders Square was originally a big-box home improvement retailer headquartered in San Antonio, Texas. A subsidiary of Kmart, its format was quite similar to The Home Depot, Menards and Lowe's with floor space of about 100,000 square feet (9,300 m2). In 1997, a Los Angeles leveraged buyout specialist acquired Builders Square and merged it with Hechinger but the new combined company failed to thrive and all remaining stores ceased business operations by the end of 1999.
