It is a big word, maybe too big a word for a project initiated by students. Then again, that is what studying is all about. Taking responsibility for oneself, for one’s surroundings, for the society we live in and for the earth we live on. There are countless opportunities to be responsible every day: for example by switching off the light when leaving the room at 5 A.M. Responsibility starts with what is already there: green areas, Altbauten, Berlin’s war gaps — instead of tearing down and irresponsibly building out of context, the Rooftop House uses existing architectural and social structures. We feel responsible for the city we love, and aim to transport this feeling throughout our house: building with local materials, using renewable energy, integrating into society, drafting a long-lasting solution.



To connect one another is probably the strongest tool humans have. Today’s problems are too complex to be solved by anyone alone or top-down. Energy efficiency and living space are not two distinct problems but one interconnected challenge. For the shift to renewable energy to become sensible and reliable, a flexible network with smart players such as the Rooftop House is just as necessary as are responsible citizens. The Rooftop House on the Altbau is not a parasite, but contributes to a symbiotic connection between old and new. Connections go beyond constructive details. We have already brought students from entirely different universities together, now we want to re-connect the slowly disintegrating city-dwellers of Berlin, sharing our ideas and passion.



Adapting to new situations and environments has always been an inevitable feature of life. Our ancestors took this to the extreme when they shifted their home from day to day. Nature does it, too: every kid enjoys watching birds on their spring and fall passage. We are not rolling stones, but we like to wear shorts in summer and scarves in winter. Why don’t our houses? The Rooftop House adapts to the time of day and the seasons through its façade and comfort system. And of course it adapts to its users, their personal needs and moods: for example, opening the bathroom doors divides the otherwise free-flowing space and lets you enjoy the skyline while taking a shower. In a bigger sense, our house can adapt to the particular Altbau situation it encounters by changing the number of modules around our Core.
