Roofs are not only the protective skin of our living and working environment, they are also the most obvious calling card of a city. With their folds and smoothness, they give a city a face, catch the eye - but also conceal many secrets. To uncover these, KaJo roamed the long divided Berlin for over five years (repeatedly interrupted by international photo trips). For six months, he also moved into a small room in a shared flat in Kreuzberg. For the trained architect, the visual engagement with urban spaces was particularly appealing. No professions are as closely related as those of photographer and architect. Both constantly oscillate, indeed translate, between space and surface - and vice versa, surface becomes space. It was important to the photographer not only to find interesting places, but also people who would hold doors open for him in the best light. The result is a multifaceted mosaic of our capital city, with perspectives that even die-hard Berliners hardly know. The photo book (with an introductory text by architecture critic Falk Jäger) was published in 2008 and was nominated for the German Photo Book Award.
