Ah! you've stepped inside. I promised you a surprise. You most probably will not recognize this building, but not to worry, I'll explain that all as we go along. You see, it's in the future where I spend quite some amount of time. It is a very comfortable place and I like to stay here when I am in London so I have placed it inside the tardis. Nice thing about a tardis, it's bigger on the inside than it is on the outside. One can stuff all manner of things into it and not get too crowded. I'll show you what it's like inside soon. Off to other worlds and other times now. Back soon. Ta Ta.
