A style of flat building utilizing corner blocks, keystones, and half-keystones. In this style of flat construction the framing members' faces (usually 1x3 or 1x4) lay parallel to the face or covering material of the flat. The covering is usually canvas duck or muslin fabric, but can be a rigid sheetgood like lauan--a hard flat. Broadway flats tend to be thinner in profile than Flat, Hollywood or Studio flats.
