Farmhouse style house numbers
Farmhouse style house numbers invariably are selected from typefaces associated with early American or colonial styles such as caslon antique. The typical farmhouse usually has a plethora of greek revival elements such as broken cornice returns, swan's neck pediments, and narrow clapboard siding.
Colonial address numbers
Because colonial address numbers are typically attached to a wood surface, it is common to find them with complementary screws or escutcheon pins. However, sometimes mounting against a surface of marble or stone is called for and in that case it is not uncommon to use a construction adhesive. Because colonial house numbers are so prominent and attract the eye it is important to select a style that looks appropriate for the style of the house.
Colonial house numbers and architectural style
There is a bewildering array of building styles that colonial house numbers would be appropriate to be associated with. The most obvious would be colonial saltbox (with or without cat slide roof), Georgian style, Federal style, Dutch Colonial with gambrel roof, and Greek Revival. But then later the Greek Revival influenced tri-gabled ell and other farmhouse styles could be workable. Then the various revival cottages from the twentieth century are a fertile field as well.
The location of the was often kept symmetrical. So colonial address numbers located centered above the front door was common, although it was not unusual to find them screwed to clapboards off to the side. Occasionally on a grander house with a porte cochere colonial house numbers could be located where the footman would dismount to open the carriage door. Depending upon the grandiosity of the estate a carriage house was an additional likely location for house numbers.
