Arend Rosema, formerly a building contractor, started dismantling and selling old building materials in 2007. Today, Arend Rosema mainly specialises in the sale of used wood that he prepares for a second life in his shed with the necessary care and expertise. The old wood is dried on site, de-nailed, planed and sawn to the desired dimensions. With this wood, Arend Rosema makes, among other things, floorboards, milled on site with tongue and groove joints, and furniture from scaffolding wood.
In addition to old wooden beams, Arend Rosema also sells board material, doors, window frames, insulation material, steel beams, bricks and other types of items, with stocks being variable and highly dependent on the nature of the local demolition trade.
