I was so inspired by some of your creations here that I decided to have a go at expanding Darby's Den. I wanted to keep it as close to the original as possible, so I simply added a second floor. Here is the result:

On the second floor I added rooms for working on skills related to the distinguished programs on Britechester - music, debating/public speaking, comedy, art, as well as an office for teachers (I intend to use that as a club room for teachers so that they'll hang around doing things like grading homework or mentoring students.)
