In architecture, shoebox style refers to the functionalist style of modern architecture characterised by predominantly rectilinear, orthogonal shapes, with regular horizontal rows of windows or glass walls. [1]
Along the same analogy, it refers to undistinguished styles of apartment houses, such as dingbat apartments.
The puritan and repetitive shoebox style is seen as a way to low-cost construction. [2]
The term "shoebox style" is also applies to concert halls of rectangular shape, as opposed to the traditional circular amphitheatre/arena/horseshoe shapes. [3]
