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.
We do everything we can to make our feline friends feel at home. They love being able to perch in high places and scratch to their heart's desire, but cat trees can be cumbersome depending on your space situation.
