Something about the sun hitting this lonely bed makes you think of a sick room, doesn't it? Sitting there in bed, the rest of the kids playing outside while you aren't allowed out. I think this makes an emotional statement off the bat.

Little chair lost: Less is more. Tiny chair: Big space--over accentuate it by showing how small it really is in the void.

This is an overbearing piece of equipment in a dark warehouse--take advantage of the light to make that imposing piece of metal look almost weightless. It's already big and dark--we know that, but look how differently it comes across when lit.

This shot took my breath away as I took it. Standing in the guts of a building, there were "windows" creating a very geometric man-made pattern and in the distance, nature--soft, fuzzy, pastel tones. The contrast was amazing. The building becomes a frame for the beauty outside.

I could have stood back and taken a shot of a wooden building, but getting beneath it and looking up the length of those aged boards made it imposing, dark, and went with the grain. The building intimidated me as I stood beside it and this shot showed just why.
Take advantage of lighting, comparisons/contrasts, ways to accentuate what strikes you about the place. Try not to shoot like a tourist who stands back and gets the entire building in one shot. The exception to this would be to get up close looking up at it making it imposing or lying on your belly on the ground shooting it to make it look wide. Do not attack your subject as if it is a model posing. Interact with it!
I hope this inspires you to shoot places around your hometown and find beauty in things that others overlook. I can tell you that, like the elderly, these buildings have history and content. They are infinitely more interesting than the smooth baby faces of the youngsters.
