Building Plan Styles

I'm trying to find a style of detailed floor plans (not architectural ones) that I'm happy with. Here is one I sketched earlier. I'm going to try some other approaches and I'll post the results here. Does it look ok? It's all hand drawn at the moment.

This looking to be an interesting approach. Cant wait to see more +some rep

Looks good.
I think that the doors could use more of a contrast to the walls so they stand out more.
