Step 7: The interior.
I used a cheap piece of green plastic outdoor carpet to line the floor and keep small toys from falling through the spaces between deck boards. Plus it can be hosed out.
The "granny's attic" area over the porch seems perfect for storing small toys that you can't reach. I can't wait to see what's collected up there in 10 years when I have to figure out how to get rid of this thing. I bet it will be like a time capsule of their favorite lost toys.
My son, the 7yo, has installed a computer on the door. He appears to be checking out www.evil.com. I blame Dr. Doofenshmirtz. (Go look it up. That's what Google's for.) Hey, where's Perry?
There should probably be some sort of guard rail around the hatch, but I haven't done that yet. For now we'll consider it a first aid training opportunity. And yes, I was the first person to fall through it. My shoulders are too broad to fit though, so I looked a bit silly. Bob didn't dial 9-1-1; he was laughing too hard.
Another hazard here is the support for the pully system. I can't count how many times I hit my head on that thing. No, really, I'm too woozy to count.
