Some variants on the Pittsburgh Foursquare from one block in Beechview. They all have the same basic layout of reception hall, parlor, dining room, and kitchen on the ground floor; three or four bedrooms and bathroom on the second floor; and two or more rooms on the third floor. Above, a fairly late version, probably from the 1920s. The lines are simpler and the roof is shallower.
Here is a well-preserved larger version with its original slate roof and multiple dormers. Note the arched window in the dormer. The bay on the left side of the house, which goes up from the dining room into the master bedroom, is very common in Pittsburgh Foursquares of the early 1900s. It allows cross-ventilation and ample light into those rooms in spite of the narrowness of the gap between houses.
This variant without the pyramid roof creates more room in the third floor.
A very large example of the Pittsburgh Foursquare, but the layout of rooms is more or less the same; they are just bigger rooms.
Finally, a much-renovated house with a gambrel roof, which probably has more room on the third floor in proportion to its size than any of the others.
