Would be fun kid hideout space! Awesome dog kennel under the stairs design idea. If you want an indoor dog house, utilizing the space under the stairs for a cozy, attractive and practical space for dogs is a good idea! I love this design.
Reading corner - I love the wooden letters (from JoAnn's painted white) the framed book covers. IKEA spice racks painted white for the bookshelves and dot rugs from IKEA. I would love to do this in a corner of our family room!
reading corner Eva Montessori approach to providing a dedicated reading area for a toddler. As soon as we setup the book display, our 18 month old found his way, picked a book and sat down to "read" by himself.
