Not exactly the answer you are looking for, but check out the books at your local library.
I was trying to find some built in shelving plans online much to your same results -- nothing with clear, step by step instructions, photos, descriptions, etc. Then, I checked out the library, and there were so many books about built-ins that I couldn't have checked them all out if I wanted to! It was really helpful because then I knew the terms I could use for better google searching as well.
But yeah, nothing beats a quick online resource, so I'll be watching this thread as well.
