Hardware makes all the difference! I also believe in the power of typography. The font of a house number, a room number, or an address plague, gives the façade its "caption" as it does in magazine spreads. Wrought iron address numbers spelled out in cursive letters have a nostalgic charm and complement quite nicely with Cape Cod or Ranch stylet homes. It can be fairly affordable if chosen from ready-made fonts and sizes. Custom made signs typically cost few times or more, but can be made in a font or color or your choice - maybe even matching that on your family letterhead.
