Most of Berlin’s apartment blocks are all 5 stories high and have flat inter-connected roofs.So far only the renovated and more expensive buildings have roof access, and are normarly only reserved for the penthouse residents.
The newly formed organisation Dachgärten für alle aims to work with locals and landlords to develop more green spaces above the city streets - for gardening, meeting-places and star watching. Join our petition and help reclaim our roof!

The project intersects with recent public debate in Copenhagen about air pollution in the city. In collaboration with Senior Scientist Jørgen Brandt from The National Environmental Research Institute in Denmark a first prototype is developed for making an indicator that can be placed in the city and display local levels of pollution as well as pollution forecasts on individual streets. The project holds an open source script for displaying data from the Internet in a variety of forms.
