You have to understand that this is not a 'substantial property'of consequenmce in itself. It was the property of a Wealden ironfounder, Wenban, and later became a farmhouse with adjoining barns when one of his daughters married the neighbouring farmer. He only had daughters and that is how the property passed from Wenban ownership. The house itself is quite compact and none of the rooms are large. In fact, its not a very convenient house to live in. The entrance was a cow byre. A corridor, also once a cow byre, now connects to the big barn which is typical of such barns in UK farms. We have several round us here in Suffolk any of them converted into houses now. A large garage with chauffeur's flat abouve was built opposite the house when it became a gentleman farmer's residence (a retired naval commander). He built a specialist pig rearing unit in the grounds.
I have some other explanatory things to say in reply to later messages posted.
