It is now a country park known as Hornchurch Country Park. A vast site and a few photos to give a flavour Part of the Peri track still surviving
Was this the site of the WW1 New Zealand "Hornchurch Convalescent Hospital." ?, Hornchurch Convalescent Hospital | NZETC
No The hospital site is about 1 mile away from the old airfield Demolished in 1936 and turned into a housing estate "Grey Towers, a crenellated mansion in Hornchurch Road, was built in 1876 by Henry Holmes, owner of Hornchurch brewery. Standing near the village, in a 50-acre park, it was the last country house built at Hornchurch, and it had only a short life. During the First World War it was occupied by the Army, eventually as a New Zealand base camp. It was demolished in 1931, and the site became Grey Towers Avenue."
