The famous Hay Hassani market in the centre of Casablanca, better known as the Ould Mina souk, is a huge flea market said to be full of treasures, between furniture and Art Deco style objects. The interior of the market is quite traditional in what can be found (vegetables, meat etc.), while two of the facades, under each arch are resellers and dealers of reclaimed construction materials and furnitures.

Working independently, each resellers offers a wide range of used materials: doors, windows, stairs, marble, sanitary, wood, metal, chairs, glass and furnitures. Transport, cleaning, repairs, repurpose, restorations, dismantling are generally services that can all be found, but will depend on the resellers and what he offers. About 2/3 of dealers have a workshop inside the arch to provide works on the materials, such as cleaning, cutting, repairs, dismantling, and repurposing.

The largest part of the materials have been provided for construction surplus which are sold, or demolitions in which they will salvage the materials themselves and buy them for a lower price, therefore the quality is quite high. Some dealers also offer a mix between new and old materials.
Private individuals come to buy materials for their homes, but also national resellers buy in quantities to later sell them in other parts of the kingdom. Ould Mina Souk is also like a hub in Morocco for reclaimed construction materials and furnitures.
