A home improvement store is a retail establishment, generally very large, specializing in various products for the improvement of residential properties, including do-it-yourself construction. It is not a wholesaler, but caters to persons seeking to improve or enhance their own homes. Wares usually include lumber, building materials, paint, garden supplies, hardware, flooring, plumbing materials, etc.

The establishment serves retail customers improving residential property and is not a wholesaler. Its range can include heavier building supplies as well as ordinary household tools.

A hardware store concentrates on tools and supplies for handiwork. The home-improvement store normally has a larger and broader building-product range.
