Kees De Vries has been trading in old building materials since 1990 on the site of his old farm. De Vries specialises in bricks: mainly Frisian yellows, Groningen red, Haarlingen yellow and apple blossom. The stones are chipped, sorted and placed on pallets on site. They also have the most common types of Dutch roof tiles in stock.

You can also purchase paving materials and flagstones in a variety of colours and sizes from De Vries. They also sell second-hand stelcon plates and smaller lots of natural stone.
