Winged Gable (or Prow). A winged gable, like the one on this house at 91st Street and Crestview Avenue, is an elongation of eave, which extends the roofline at the peak of the gable. This architectural feature, which is also sometimes called a “prow” because it resembles the prow of a ship, would have functioned to provide some additional shade or shelter from rain to windows or doors beneath the gable, but was just as much a stylistic choice as a functional one.
