Something I have been checking out a lot lately is Architectural Salvage places, and being rather inspired by things like this. It started as plans for when we lock down a house, but its obviously blending well with this effort as well. I'll toss in a few links to some sites that show some pretty cool stuff, that might get you thinking.
Architectural Salvage Inc.
The Brass Knob
Old House Salvage
I just visited that first one, down in Denver, on the weekend. I wanted to take half the place with me. That push plate I linked up top was tough to walk away from, even at $95. Trying to reason out how I'd get mantles and oversized doors home in my suitcase has haunted my dreams since.
