Haus der Materialisierung is an association of various local initiatives and institutions that research, practice, and work on the topics of sustainable management and climate-friendly use of resources.
...and it works!
I often go exploring into random and dilapidated areas of Berlin. I like the thrill of finding new nooks and crannies with strange visual sites. A few months ago, an old housing colony was abandoned, and many objects (such as couches and front doors) were left at the edge of the city to rot or to be scavenged. This is a view from a non-descript area of the S-bahn train tracks (between Sonnennallee station and Treptower Park station) into the most Southern part of Neukölln district.
Kw is a great art institute situated at the backyard of a very eastern part of town, place for many other small galleries. Auguststrasse is worth the walk and Kw is worth the stop.
While strolling around Mitte, check out the flagship store of Berlin´s cult women fashion brand. (And try a delicious cinnamon bun at Zeit für Brot next door.)
On a leafy street in Kreuzberg is Kuratiert, a contemporary illustration gallery and shop selling prints, ceramics, textiles and more by some of the best creators from Berlin and the world. It also hosts regular dedicated exhibitions, and is a great place to browse for gifts, or just inspiration.
