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.
Small room idea Wandering on Wheels 2 - It's like the bed is on a mini deck with storage cabinets + drawers beneath. Better than plastic bed risers + plastic bins! Do I spy an open pet door in the side of the steps?
