The ITimes article above says the whole estate was sold. It’s possible the registration was split but so far there’s only one entry and it says “dwelling and lands” which is unusually specific.
The land sale will not appear in the property price register. The solicitor will apportion the sales price between house + 1 x acre of land and the balance of land.
The new owner is wasting no time. Two wood-frame cottages are under construction next to the beach.
No sign of a planning application online. Where on those 5,000 acres would they put the site notice?
