Where can i find a dollhouse kit that looks like hogwarts?

my mom is really into dolls and i really like harry potter, so i thought it would be a fun project to build a doll house that looks like hogwarts from the harry potter books. i've tried finding harry potter dollhouses online, but they're all cheap plastic toys made in china. I want a kit that's made from wood, like the amazing dollhouses they show in gothic horror movies, something that will last for when i have kids of my own. i've looked for castle kits and cathedral kits, but haven't had much luck.
