Generally established on the outskirts of major towns and cities, Leroy Merlin stores are large centres (9000 m2 on average) providing self-service and sales assisted services. Its business is centred on six main sectors: DIY, building, gardening, sanitary equipment, renewable energy, and interior decoration.
In 1923, Adolphe Leroy and Rose Merlin, associates in private and business life[clarification needed], opened a business of American surplus. Strengthened by this first success, they decided to sell DIY products and supplies at moderate prices. In 1960, the firm was named Leroy Merlin. It became a precursor, as it was the first company to offer free delivery services.
