This might be the coolest playhouse we've ever seen. Logan's grandparents wanted her to have a special place to play — and boy did they deliver. They had this 350 square foot, two-story, Harry Potter-themed castle built for her complete with notable locations from the film like Hogwarts Castle, Platform 9¾, and Ollivander's wand shop. Talk about magical, it's hard to believe playhouses get any cooler than this. Where can we get an invite to this place?
