Living or cruising around a city, the average citizen never gets a chance to enter some of the most fascinating buildings. But this weekend, a very special Tel Aviv event allows laymen to step into a diverse group of largely Bauhaus-style architectural gems - private homes, a hotel, the courthouse and even the sewage pumping station in Jaffa that rocks non-stop. Architect and Bezalel Academy Professor Alon Bin-Nun experienced the Open House concept when he was in New York (the event also happens in London), was smitten with the idea and became passionate about bringing it to Israel. While the idea is primarily about architecture, Bin-Nun sees the concept in somewhat idealistic terms. As he says: "It's not just about opening houses but opening hearts - and reducing the alienation you normally feel in an urban environment." Organizing the event, Bin-Nun discovered the municipality was very enthusiastic, as were scores of Tel Avivians who felt a responsibility to invite people to peer inside their historical, spectacular or simply fascinating buildings. Houses from Within offers a broad range of architectural delights, and since it is not a tour going from one building to another, participants are free to choose whatever interests them most, whether that be preservation, architectural theory or municipal structures. Some open houses offer educational tours led by architects, while others are simply opportunities for self-guided snooping. There's really something for everybody, and Bin-Nun is tickled by what he calls the "open, democratic" nature of his event, exposing what's behind the closed doors of Tel Aviv.
