Update I have now pinned this print down exactly, it was commissioned for the book I publish: Delineations Historical and Topographical of the Isle of Thanet and the Cinque Ports by Edward Wedlake Brayley, http://www.michaelsbookshop.com/catalogue/delineations_historical_and_topographical_of_the_isle_of_thanet_and_the_cinque_p.htm the plate for the print was engraved by William Deeble in 1817 and was taken from a drawing by HENRY G. GASTINEAU (1791-1876) who was a topographer and landscape artist. He trained as an engraver and then studied at the Royal Academy Schools, after which he travelled extensively in Great Britain painting the scenery as he went. He was elected Associate to the Old Watercolour Society (AOWS) in 1821 and became a full member (OWS) in 1823. From 1827, Gastineau worked in Camberwell as a drawing master, where he died on January 17th 1876.
The square towers on the left are the outbuildings to Eastcliff Lodge, these are still there and the Italianate greenhouse is built against them. the pointed towers on the right of the print are those of Eastcliff Lodge itself. This once stood in King George VI Park, obviously it was bought by the council and demolished.
I have added a picture of Eastcliff Lodge by JMW Turner for clarification. As far as dating the print goes Eastcliff Lodge first appears as occupied in 1803 as a summer residence of Queen Caroline, so it was probably built around 1800.
Obviously it as after 1817 when The Clock House was built by Benjamen Wyatt and George Louch.I will add to the historical notes as aspects occur to me.
