So I've been redesigning the playhouse dormer roof as I build it, because I have a last minute inspiration to allow the dormer roof to open up to the sky (under adult supervision of course so no body falls out!). Recently I discovered that Renee enjoys astronomy. Last month, we took the kids to the Academy of Sciences in San Francisco's Golden Gate Park. One of the things we saw was a planetarium show, which displayed the different constellations, and Renee remembered a lot of information from the show. About five days later when we were driving home at night, Renee recognized the three stars of Orion's Belt in the night sky. She remembered the story of how Orion the hunter protects the stars of the Seven Sisters. I am quite impressed that she remembered, so much.
As I sometimes work on the playhouse at night, I discovered that on a clear night, the playhouse loft has a great view of the stars. So I plan to build removable roof panels. Then we can still look up and see the stars. When the playhouse is done, I'll get a little astronomy telescope for us to star gaze with the kids. Maybe Renee will grow up to be an astronomer or astrophysicist!
So I sketched the concept below, which I think will work. It took me a while to figure out how to make the roof relatively easy to open and still keep the roof rain water tight when closed.
