never too old for a tree house

We built this tree house for our son Alex when he was younger and he and his friends used to spend hours playing in it. It has been a little neglected in more recent years. The grandkids love playing in it, but it definitely needs a little love to bring back that magic that it used to have. I saw these amazing fun sheds on Pure Style Home last May and decided this was going to be my next little project. The one with the chandelier? I mean, come on. Not that mine will be quite to this level - I still want it to be a playhouse - but I have a few little ideas brewing around in my head. I was thinking of painting it taupe and the swing white, adding some curtains and maybe even a little chandelier.

Anyway, just as I was starting to make plans for this project, my son Al came home from college. Seeing as I had sort of kicked him and his friends out of the guest house, I guess they were looking for a new place to hang out. Seems you are never too old for a tree house...

So, instead of curtains and a chandelier, the tree house got a dart board and guitars. They have moved on from the guest house though, so its fine be me. It really just kind of makes me giggle that these college boys that used to play in this tree house have returned back to it.

The downfall is that now, instead of finding them sprawled about the guest house, they have just taken to sleeping on the back patio... oh, college boys.

I actually don't even know who this is...

Well, Alex leaves for Rome in just a few short weeks (*sniff, sniff* this is where I get emotional and decide he can sleep on the back patio as much as he wants if he just stays home with his mom a little longer...), so I guess the tree house will be mine again. Thus, it is time to start the planning. So, ladies (and any of you fellas that are reading out there), what fantastic ideas do you have? Please do share! What would you do to fix up this lovely old tree house?
