Our company was founded three generations back by T.C. van den Dool in 1934 on Leeweg in De Lier in the Westland region of the Netherlands. The company was established because the N223 provincial road to Delft was built by the government at that time. The nursery he ran was located along the planned route of the N223, which forced him to move. He devised a way to roll his Westland-style grape growing greenhouse along rails to an adjacent plot. Due to his success, fellow growers approached him asking if he could do the same with their greenhouses. This signalled the start of the company that has evolved into Dool International we know today.

During the second world war, the municipality of 's-Gravenzande commissioned the company to move greenhouses to make space for the construction of the costal defences known as the Atlantic Wall. After the war, the flat panes of glass used to protect vegetables were replaced by taller, wooden constructions with an arched glass roof. This type of greenhouse was known as the Venlo greenhouse, named after the Dutch town of Venlo, where they were first developed. Every few years, growers had to bring in a new layer of substrate to grow their crops on. Adding this layer reduced the distance to the roof. Van den Dool was able to lift the Venlo greenhouses with jacks and lengthen the wooden pillars by placing chocks underneath them. Moving the old, Westland-style greenhouse also continued.
