Some reading nooks:
Here's an idea for the nook that is now my closet.
What a fantastic use of a very tiny space!
Kids love nooks!
Perfect for utilising the space under the stairs.
How about this for some jaw-dropping fabulousness!
Or this one! Words fail me!
On to a couple of office nooks:
I wouldn't mind my office being a nook, if it was as fabulous as this!
Love the white, the colour provided by the books and the lovely Danish chair.
A sleeping nook:
How I would love to cuddle up on a cold winter's night, the open fire burning.
And finally, how to make a nook:
If you have a tiny space in your home that you don't know what to do with, such as the end of a hallway or a built in closet (on the remote chance that you wouldn't need it for storage), why not make it a cozy nook? The basics of a nook, for me, would be wall to wall seating (or a desk if you're making an office nook) and some shelving all the way around. This defines the space as a nook, as opposed to just a small space with some furniture in it.
