Well done johnfilmer, it is indeed 5 South Cliff Parade, Broadstairs.
The Owner/Builder was Francis Edward Howard Paget and was a noted member of Society. He set up the Dorking Brick Company. His ashes were scattered at Sea in front of his Home (Dumpton Gap).
The original grounds had a garden workforce of 25. Some of that was sold off for Building by a later owner.
