In the late 19th century Salhouse Road seemed to be a road that people avoided, this reluctance in all probability was it was site for the city's isolation hospital. Much of the land which has now become the Heartsease Estate had originally been a cavalry ground but with the advent of World War I it became an Aerodrome. Not only were there the associated buildings but the firms of Bolton and Paul and Barnard's had manufacturing facilities for both aircraft and war effort. Whilst some of these buildings have been lost during redevelopment many of the original buildings are still in use a century later. Until the city council took over the land which had originally been the airfield and converted it into a housing development there with minimal residential property of the Salhouse Road with most of the development taking place on side roads. With recent developments in the area has become virtually all retail or industrial in character.
