So, it isn't just a place to hang cloaks. It is more fundamental than that. It's a bog.
When we planned the roof room we decided that space was precious. Furthermore, the plumbing advice was that water pressure would be insufficient for lavatorial purposes at the top of the tower.
I remember standing in the skeleton of the roof room at CSi in Hull and thinking to myself that the space behind the lift shaft was wasted and it would be enough for a shower room, toilet etc.
Actual usage of the roof room revealed an irksome deficiency - the lack of a toilet, which necessitated a trip downstairs - or for gentlemen an opportunistic, and exhibitionistic pee over the side.
Well, I have spent some weeks constructing a 'cloakroom' behind the lift and it is is at last finished. Water pressure concerns have proved unfounded. It works and I am proud of it. Pictures tomorrow, if I can lay hands on the camera.
Prepare to be amazed.
