This strange building is behind the restaurant Bella Vita on Sun Street. It’s either a terrible nightmare for an architect to ‘read’ or an absolute thrill to ‘decode’. I suspect (as do others) that it has been cobbled together from lots of other buildings (Cheap materials) I really enjoy looking at it, but make if it what you will. Derek Wheeler of ‘The Hitchin Historical Society’ has suggested that it was part of the Girls’ School that was run in Roslyn House during the 19th Century; and that later became a furniture shop until 1910 (approximately), accounting for the mélange of styles and building materials.
(Update) Since I last took it’s photograph, the building has lost its little curvy stairs and there is a huge pile of bricks to the left of where the stairs used to be. I wonder if they are going to re-do them or do a disabled access ramp? Who knows?
