Actually, Richie, the style of the houses was more dictated by the economics of the neighborhood than the era. The majority would have been your typical middle class, these would have porches, big windows, 2 maybe three stories, and many times a small front and back yard. The blue collar housing would be smaller, les detailed, and front right on the sidewalks. Even the upper crusties would have rowhouses, only these might be called "brownstones" with high ceilings, large rooms, and a deeper footprint...almost always 3 stories.
In these neighborhoods, there would be a row of small houses, called "alley houses" in which would reside the servants who tended to the big houses.
With a few changes in detail, this was pretty much the case from the end of the 19th century until about WW2. After the war, there were still a lot of rowhouses being built (Ed lives in one of these, and I grew up in one) which were wider, but less deep, usually brick fronts, simple front porches, and minimal detail.
It's really a very interesting social history to look into.
