Utterly bonkers, but brilliant

I've just come across this, in a random issue of Building Magazine (don't ask, I read some odd things for work...). It's called Hotel Monument, and is an installation planned for Grey's Monument in Newcastle, with a single hotel room at the top (complete with the lovely Earl Grey, who normally looks like this, and will be looming above you somewhat as you sleep).

When can I make a reservation?

Update: lots more info here
