What are some buildings with a notable sawtooth roof? (preferably public buildings)
Saw-tooth roofs were first used in the 19th century to provide light (daylight in the absence of artificial light) to industrial building. Few of those early buildings could be qualified as “famous” except some like the
Saltaire Weaving Shed (above) which has been adapted to retail uses.
Ok so there's too many choices to pick a favorite building, but what about your favorite style of architecture??
That one is easy: Modernism.
Modernism is the single most important new style or philosophy of architecture and design of the 20th century, associated with an analytical approach to the function of buildings, a strictly rational use of (often new) materials, an openness to structural innovation and the elimination of ornament.
