In the beginning of this book the author points out that a culture is reflected in its buildings. Then he goes on to identify the events that caused the various styles--the War of 1812 that stopped our imitation of English architecture, the change to stud framing and the effects of industrialization that mark the Victorian era, the nationalistic spirit of the 1876 Centennial that spawned the revival in Colonial archictecture at the end of the 19th century, etc.--in such a professional style of writing youd never suspect he was also an architect. A history professor maybe. All of which explains the subject better than the usual bare chronological sequence.What helps in a book like this are the odd bits of information casually thrown out that show mastery of the subject.
Colonial homes were never white; Greek Revival were never anything but. A particular cornice is usually done incorrectly, compared to the true Classical version.
He also make the sensible point that you can only compare styles within limits, that at some point youre really discussing altogether different building types, as in ranches, bungalows, and certainly octagon houses. And early on he boasts he can design a modern four bedroom house in any style. Then he proceeds to do it, providing a front elevation and a repeating ground floor plan (front: LR, center hall, DR. rear: family room, kitchen, mud room) with added porch, tower, fireplace, chimney, as needed. Not so much to explain the architectural features, I think, but to give the prospective homebuilder something that actually could be built today.
Where most authors stop around WWII, he continues up to the present. His next-to-last chapter shows the recent builders styles which will be familiar to anyone whos driven through any of those vinyl village developments with the Olde English names: the Townes, Pointes, Glenns, and Harbours. Here he doesnt hesitate to criticize the tastless examples, and continues his tirade into last chapter, where he argues against the Post-Modern assault on tradition in favor of a return to order and careful design.
