While designing spaces, sometimes we come across odd corners which are difficult to use for the usual functions. I have often made good use of such corners by converting them into reading nooks. There is nothing more relaxing than curling up in such a space on a Saturday afternoon with a book (or a kindle!).
Some clients that I have interacted with have come back saying that such spaces have encouraged children to read more. Kids also begin to understand that books have greater value in our lives than toys.
Creating such nooks is usually inexpensive. There is no expensive piece of furniture to be brought. The design of the space is usually a factor of the odd corner itself and one can pick up inexpensive, comfortable furniture.
