Several of these houses have fallen into the hands of house-flippers, which means that they have been made presentable with cheap materials that disguise the architects’ original intentions. But we can be grateful that they were rescued by capitalism from otherwise certain decay and demolition.

We begin with a design that, from certain angles, looks almost like a stretched bungalow. The part that is covered with vinyl siding was probably wood-shingled, although it went through a half-timber-and-stucco period that might also have been the original plan.

Here is a tidy little bungalow with no stretching at all, and it seems to retain almost all its original Arts-and-Crafts style.

Nothing says “flipped house” like vinyl siding and snap-on shutters for the windows. But the twin gables with swooping extended roofline show us the romantic fairy-tale cottage the architect meant this house to be. The top half, again, was probably wood-shingled; more recently it was covered with asbestos-cement shingles.

This unusual house brings more than a hint of the Prairie Style to the back streets of Dormont. Plastic cartoon shutters again, but those could be removed by the next enlightened owner, leaving an exterior almost completely original. The patterned brickwork is eye-catching without being garish.

The sunroom protruding from the front was probably an open porch when the house was built.
