Leen Van Velzen has a compact but impressive stock of reclaimed building materials. First of all, the collection of 5000 doors is an eye catcher, all of which are personally dismantled from homes all over the Netherlands. Leen himself is passionate about antique ensuite doors, but the range also includes Bruynzeel doors, stained-glass doors, simple panel doors, front doors, etc. Some antique doors that Leen offers, have already been restored.

Leen also has matching hinges and locks, a special collection of antique sanitary appliances and a small selection of staircase components and fireplaces. The website offers a good overview of the various items on offer, but does not show the full stock. For large orders, the company can organise transport itself.
