Here's a photo of my son Roland's bed (on the opposite wall of the bed in the first post) Note that the ladder is attached at the foot of the bed, rather than at the head of the bed. You can also see the 10w hallogen lamp in the corner. The lamp has an in-line switch so the kids can turn it on and off.

p.s. The cat on the bed is not included in the plans :0

We had to modify it slightly as it wasn't going in a corner but your design was perfect for what we wanted to do. As is was to be a spiderman room, we added a web shaped rope ladder :)
