I am a big fan of Edwardian and Arts and Crafts architecture and design. I am always excited, but sad when I get the chance to explore anything built in that architectural style. I certainly agree the outsides of many older buildings hold a lot of intrigue, but on the insides, there are finishings, doors, door frames, and other little things you wouldn't see in even slightly more modern buildings, but they captivate just as much.

I love old staircases. This is one of a few I've found in old buildings.

Old fireplaces, built-in cabinets and shelves, love those too...

Not a fan of painting on brick, but the spires in those houses redeem them for me...
