Eastcliffe House was designed by Henry Clutton for Nathaniel Clayton of Clayton & Shuttleworth. The house was built between Sewell Road and Lindum Terrace in 1877. A grotto was constructed in the 1870s in the grounds of the house, Pulhamite mortar was used to make garden features including paths, flights of steps and a bridge over a pond. The grotto is now in the grounds of 12 Lindum Terrace, the bridge has not survived.
Nathaniel Clayton died in 1890 at the age of 78, his wife had died three years earlier.The house was offered for sale for a number of years and eventually became residence of Henry Elsey.
The house was auctioned by Henry Elsey in 1920, not sure if it sold, it was demolished in 1926. Many large houses were demolished it the 1920s and 1930s, there was a shortage of raw materials and the stone, wood, etc of the houses was worth more than the complete buildings see https://itsaboutlincoln.blogspot.com/2017/01/sad-end-to-grand-country-house.html. Another reason was the shortage of domestic staff, women had got their "freedom" during World War One.
