קרוואנים, caravanim) is an Israeli term referring to a portable building used as a living space, school classroom, synagogue, or community center.
They are not insulated but can be outfitted with heating and air-conditioning units, water lines, recessed lighting, and floor tiling to function in a full-service capacity.
[2] Caravanim are popularly employed by schools — especially in Haredi neighborhoods of Israel — that are unable to finance a permanent structure.
[8] The overnight installment of caravanim for housing is a popular means of establishing a new,[9] unauthorized settler outpost on disputed land.
Caravillas, which vary in size from about 650 to 1,000 square feet, are akin to the Israeli concept of a villa, or single-family home.
