New Project

Need some design help. The main idea is a castle bed for Katie on her 3rd birthday. May end up waiting longer, not sure. I have a main structure idea and hopefully will get around to posting some pics of my sketches, or even screen shots of the model.

I have three towers that I'm not sure what to do with.

I've thought of boring things like shelves or drawers that will be useful for organizing things, but it would be nice if it was geared more to play. A tower is about 2ft square, so there isn't a whole lot of room to work with.

Maybe a ladder on the inside that goes up to a trap door to enter the top bunk?

Maybe a fireman's pole to slide down?

What other features are there to make this more interesting.

The reason there is no forth tower is that I plan to make a tunnel to a slide in the back right corner.

One tower I plan to cut windows in to climb up from the outside. This would be the main way of accessing the top level.

I would like to make a sliding door/secret passage, but not sure where to put it.

What about some board space? Chalk board, white board? Should I put a metal plate behind it so you can stick magnets on it?

What about doors? I was planning on making the front just an open arch, but kids seem to love doors. Windows to the outside of the house will be in the back center, so I was wanting to do some cut outs that would project a fun image inside.

What about a light switch that controls a rope light that runs around the inside?

Right now the design is for the top bunk to be empty, but what about putting a tower or room up there?

Climbing net? Maybe a rope bridge between two towers instead of a wood platform.

Fake fireplace would be fun, not sure where to put it, but probably in the lower section. Though that area I want for sleeping mainly.

So I could use some more ideas as I design this. I have a basic structure design that I like, but want to add more.
