In April 2012 we have one for Ballast Nedam graffiti workshop cared for on location in Rotterdam. The workshop was part of one team day. After the basic exercises have been completed, a theme is then worked out in subgroups on separate canvas canvases, these are given a place within the company. The graffiti workshop is used as a creative team building activity. View the overview of all ours workshops or request information through our get in touch page.
