Many of the subjects for the ideabooks that I write come about by 
browsing through photos on Houzz. Regardless of what sorts of filters 
I'm using (exterior vs. living room, modern vs. contemporary, 
metropolitan area, search terms, etc.), I always find something new, and
 eventually I'll see a common strand that reveals a design story. Other 
times some aspects of a design are so unique that they stand apart, 
resistant to be lumped in with other houses. I've assembled some 
examples here, designs that share the trait of making me think, "That's 
interesting!"
