Peter Loojien operated as a construction and demolition company for 50 years and from there began to sell used building materials. The building materials released during the demolition process are selected and then stored in the sheds. In addition to various types of wooden beams, there are also doors, tiles, window frames, sanitary fittings and radiators. Roof tiles (especially the “Tuile du Nord” variety) are sorted by size and type and carefully put on display next to the shed. The company sells mainly to local private individuals and renovation contractors.
