Almost collapsing with its over-ambitious jettying. A steely glint of glass in one of the high windows. Inside, a world of twisted staircases, wood blurred and polished by two centuries of hands touching and rubbing, massive floorboards which dull the sound of footsteps. Huge rooms with ornamented plaster ceilings and very little light. Tiny snugs and cupboards and linenfold panelling.
