Your analasis ignores that the prices you quote contain a lot more than the pure real estate costs, but also running costs, that Wytham Abbey of course would also have to incure, such as:
Mainenance, renovations, etc (this can be quite a lot for an old and listed building)
Utilities, etc. (Again, this is a large old space not built to modern standards and this is probably quite high)
Costs for IT equipment that needs to be regularly replaced, furniture that needs to be replace ocasionally, any kind of office supplies etc provided
Council tax
Costs for cleaning, etc
Costs for staff managing the space
(Potentially, not sure if the prices you quote include this or not) catering and other services provided
I probably forgot something.
Also I doubt that the organisations that run these venues occur a lot of profit, so the total costs they charge are probably mainly the things above plus some capital costs for the building plus costs for the time the building is not occupied.
