montbrun castle secret room... I love the idea of my bedroom being hidden. I want to have a dressing room, I think it would be cool to have a hidden entrance to my bedroom through the dressing room. I would want it to have a spiral staircase hidden in panelling, just like this, or even have a private half of upstairs accessible through a staircase hidden next to the main one.
I love the "outdoor room" aesthetic. You're apart of nature but you feel secure because you understand your sense of place. It may sound corny, but if I were an urban designer, I would have these faux-ruins in public parks. It may not be authentic, but it's certainly interesting
