Architects have been experimenting with the potential of building envelopes for years. Now, Arup has an interesting, Zumtobel Group Award-nominated proposal: the Solarleaf bioreactor. This thin, 2.5 x .07 meter panel, when attached to the exterior of a building, is capable of generating biofuel – in the form of algae – for the production of hot water. More efficient than electricity and more sustainable than wood, algae is ideal kindling for producing heat, especially since it can be grown on-site. Moreover, the water in which the algae grows also collects solar energy, providing an additional supply of heat. More details on this sustainable innovation, after the break.
After winning the design competition for Germany‘s tallest apartment tower in January, Frank Gehry‘s project for the building on Alexanderplatz has already run into problems over fears that the 150-metre building could be too heavy for its site. The German edition of the Local is reporting that Berlin‘s Senate has placed the plans on hold because of the building’s proximity to the U5 branch of the U-Bahn tunnel, which it fears could be crushed under the weight.

Frei Otto, German architect and structural engineer turns 89 today. The 1972 Munich Olympic Stadium is perhaps his best known work. The pioneering tensile structure, which stood in considerable contrast to the strict, authoritarian stadium that was its predecessor, was meant to present a different, more compassionate face for Germany. Today, Frei Otto is still active in practice, working alongside architects such as Pritzker prize winner Shigeru Ban on the Japanese Pavilion at Expo 2000. Thanks for your contributions and Happy Birthday Mr. Otto!
A plan to build 4,700 homes on the site of Berlin‘s Tempelhof Airport was blocked by voters this weekend. The airport, which was built in the 1920s and has a long history as a key site during World War Two and the Cold War, was closed in 2008 and there has since been a debate over what to with the vast site, including a 2011 competition to transform it into a park and other facilities, and an outlandish unofficial plan in 2009 to create a 1km high mountain on the site.
However perhaps the the most popular idea has also been the simplest: in 2010, the airport was opened to the public without any changes, and become an impromptu urban park popular with kite-flyers and roller-bladers who circle the site’s runways.

The Bauhaus school of design has made an indelible mark on the world of architecture, one that is still felt almost seventy years after its closing. After moving the school from Weimar to Dessau in 1925 to avoid confrontation with the Nazis, founder Walter Gropius designed a series of semi-detached homes for the design masters teaching at the Bauhaus. This small neighborhood, nestled in a pine forest near the school building itself, was an idyllic home for the likes of Lyonel Feininger, Oskar Schlemmer, and Gropius himself. They were abandoned in the 1930s as Germany plunged into war, and suffered years of damage from military conflict and neglect. Renovations to the houses began in 1990, and now, 24 years later, the Bauhaus meisterhäuser have been completely reopened.
GRAFT and Kleihues+Kleihues has teamed up with Genossenschaft für urbane Kreativität (Cooperative for urban Creativity) to realize a complex of five towers centered around working and living in Berlin, Germany. Titled “Eckwerk,” the new complex is set to rise within the confines of an existing viaduct, whose shape and materiality served as the project’s main source of inspiration.
J. Mayer H. has won an invited competition to design “Volt Berlin,” a new “shopping and urban experience” center near Berlin’s Alexanderplatz. The winning scheme offers a variety of experiential offerings, including multi-brand shopping, an indoor skydiving and event space, and a 7,500 square meter hotel, all within a single cubed complex whose organization is based off an uneven grid.
