I want to build a playhouse

I'm sorry...I've never really built one...I had one when I was younger though. We got it from someone and it wasn't anything fancy. Kids will always use their imaginations though. I used to build forts ALL the time...I was a tomboy so I mostly hung out with the boys and tromped around in the woods. My son has built his own forts. Last year he had one that we would help him with every now and then but for the most part he did a lot of it himself. He made his own little "peep holes" and had a bunch of other ideas. We added things to it throughout the year. I would love to build a nice big one for my little girl and it would probably be from scratch although the kits look really nice.
