Two photographic series by Keld Helmer-Petersen and Martin Ransby, both depicting the former IBM headquarters in Lundtofte, north of Copenhagen. In the late 1970s Helmer-Petersen, working as architectural photographer for the architect Jørgen Bo, photographed the newly built complex: polished and white, set among low hedges and neatly planted young trees. In early 2021 Ransby came upon the same buildings standing vacant and worn, the young trees grown tall and unruly. Helmer-Petersen had unrestricted access inside and out; Ransby approached from the back, where entry was forbidden, moving along the periphery of the site. Together the two series form a visual dialogue across time, and the book leaves room for what happens in the space between the photographs and the two experiences.
