"Heritage destination, "
Are you joking - have you visited C# House?
It gives the impression of an Edwardian telephone exchange and if more than a half-a-dozen people turned up at the same time the library would not be able to cope.
Unless the listening facilities have radically improved over the last 18 months more than two people would be capacity.
It no longer serves as visitor friendly - if it ever did (though one time in the dim and distant past it had a shop that catered for two people at a time - no longer, alas).
