These are the kinds of things that just make my day.
I found this picture in an article at TreeHugger.com. The architect described it thus:
"We created a secret staircase, hidden from the main reception room, to access a new loft bedroom lit by roof lights. Limited by space, we melded the idea of a staircase with our client's desire for a library to form a 'library staircase' in which English oak stair treads and shelves are both completely lined with books. With a skylight above lighting the staircase, it becomes the perfect place to stop and browse a tome."
Now, I have to add a loft in my future houses ... because for someone such as myself, who has a hard (nay, impossible) time leaving a bookstore without a purchase. A tome of this ilk would be welcome indeed; complete with a round room at the top of said stairs: a perfect writer's room.
I wonder if they have it organized by genre or subject or author... or color??
