Protecting listed buildings: transformation and preservation
When the World Heritage Committee decided to make the proposed Berlin housing estates World Heritage Sites in July 2008, this was thanks to their major influence on urban development and architecture in the 20th century. Their ambition to improve housing and living conditions in the city also played a role. The decision was also in line with UNESCO’s strategic aim to protect more modernist sites. The estates stood out not merely for their huge international significance, but also for their good state of repair. Deutsche Wohnen made it its mission to maintain this and to preserve the old buildings whilst offering the comforts of modern living. We have many years of extensive experience in the refurbishment of historical monuments: around 30,000 of the units we own are in listed buildings.
When we carefully refurbished the listed UNESCO World Heritage sites from 2009 to 2013, we took care, for instance, to reproduce the distinctive colour schemes on the estates. To make the buildings more eco-friendly and sustainable, we upgraded the energy efficiency of the building shells and insulated the attic storeys and basement ceilings. Gardens and green spaces were also spruced up in line with landscaping principles. By 2013, we had invested around EUR 41 million in refurbishing the estates.
