Thread: Building a Bed Loft

I'm not sure if this is the right forum, so I apologize if I've made a mistake. I have a question about building a loft bed. Basically, what I would like to do is build a bed with a full mattress on top; underneath the bed, I'd like to have a desk (for my computer). On one of the walls, I would like to build in a wardrobe with two drawers underneath (the wardrobe would hold clothes hangers and the drawers would hold things like socks).

Here's my question: how much would something like this cost? And is it possible to construct this consuming a minimal amount of space?
