On Tuesday, June 15, 1:1 Architects Build Small Spaces opened at the Victoria and Albert Museum in London, England. For the show, the V&A invited 19 architects and firms from around the world to design small retreats and choose seven structures to build at full-scale in and around the museum. On display are designs by Studio Mumbai Architects from India, Rintala Eggertsson Architects from Norway, Helen & Hard Architects also from Norway, Vazio S/A from Brazil, Terunobu Fujimori (who we profiled in our May 2009 issue) from Japan, Sou Fujimoto Architects also from Japan, and Rural Studio (a project of which we wrote about in our October 2009 issue) from the United States. The projects range from a wooden tower that holds thousands of books to a "tree" made of sheets of acrylic to a faux garden under five split ash trees. Admission is free so be sure, if you're in the London area this summer, to stop by before the exhibit closes August 30.

Today, Thursday, June 17, Hanging Around: Modern and Contemporary Lighting from the Permanent Collection opened at the Philadelphia Museum of Art. The show explores fixture designs from the years after World War II with works by designers like George Nelson through the 1950s with iconic pieces like Poul Henningsen's PH series to the current decade with pendants like Marcel Wander's Zeppelin lamp (left). The exhibition, which runs through October 10, features approximately 20 lamps on display. For our favorites, pick up the new July/August 2010 Energy issue for our Dwell Reports on pendant lights.
