This hotel is housed in two iconic buildings: the KAS bank building from 1908 and the adjacent Rijkskantoor for the Money and Telephone Company from 1927. Both national monuments have been sustainably heated and cooled by Vaanster using an ATES system since 2016. We are proud to contribute to the sustainability of these historic properties!
