Stone for backsplash in kitchen or possibly use it in the hallway like this? This small space is probably the most interesting in the house. Stone archway with wide plank wooden floors lead to the kitchen.
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.
