Perhaps an option for a future replacement of the Plateau café would be a similar steel frame building, except with windows and modular units aligned inside ? Could be a robust, flexible and quick to construct solution but would probably lack character ?
Peter, you know those pedantic Town & Country Planner types would never approve! ;-)
Although if it was a Planning condition to have character, there are plenty of characters hanging around the Plateau Chateau that may well meet the required criteria.
Anyway is the Plateau Chateau not a listed building?
