My friend sent me a link recently to this amazing spiral staircase featured in Apartment Therapy. The walls surrounding this beautiful staircase are lined with bookshelves. Can you imagine? What an ingenious idea for a library!
You can read about how this beauty was constructed here. All of that light streaming in is natural light which makes this staircase, quite possibly, one of the of the coolest I've ever seen. Hope your week has gotten off to a great start!
