In october 2017, Peter Kroesen has been registered as architect in the Dutch national register for architects (arcitectenregister). Being officially registered allows you to use the (protected) architectural title.
Because of Peters German education and French-experience (he was registered in France for more than 10 years), his registration had to be converted into a Dutch one. This conversion has been completed lately!
Peters number in this register is 1.171001.002
