Apartment Hotel, Jerusalem, Israel, 1974 Project Not Built
"Rudolph designed this apartment hotel for Pan-Lon Engineering and Construction Company on a hill site in Jerusalem. The project proposed to excavate the hilltop and then replace it with a building that followed the contours of the site and became part of the landscape. Using the dimensions of a hotel “single room” as a module, Rudolph designed this hotel (with more than three hundred-units) as a series of parallel concrete vaults resting on a concrete frame and clad in local stone. The Six-Day War stopped the project."
