This again is probably the back of the house, although the greenhouse you would think would be at the back.
Is that a square tower showing between the 2nd and 3rd chimneys from the left?
Do you think it could look out to sea from that glassed tower?
Many large houses were taken over as RAF officers mess, could that explain the tower?
The only other thing I can think of is it now used as a clubhouse for, golf, cricket, tennis etc.
As you will be able to tell, I have no idea!!
