The Kettwiger Tor office building features an eye-catching high-rise façade dating from the 1950s and a one-and-a-half-storey base structure. The heritage-protected office building was upgraded to the latest technology and energy-efficiency standards in the course of an 18-month refurbishment project. The heritage authorities were closely involved in the project to ensure the original appearance of the high-rise façade was largely retained. The sustainability of the property is documented by certification according to DGNB Gold.

The Kettwiger Tor office building is situated in Essen city centre, north of the main railway station. The station is around 400 metres away and can be reached in just a few minutes. The immediate neighbourhood contains many shops, restaurants and cultural amenities, which all contribute to the quality of the location.
