The office of Goeie Grutten Impact Fonds is located in an ancient warehouse in the Havendijk in Gorinchem. It was built in 1859 by Jan Blankers who was a corn dealer. In 1946 the warehouse and some neighbouring buildings were bought by Jan Bastmeijer and Sons, a wholesaler in groceries, confectionery and wines and producer of low-alcohol liqueurs. From this warehouse, business was carried on well into the 1960’s and it was only in 1968, when the wholesaler merged with Envema Nettorama that business became less.
In the 1990's Bastmeijer jr bought the warehouse from his father and had it renovated. Since then this characteristic building with its modern office facilities, multifunctional rooms and lovely garden has provided room for various entrepreneurs.
