This map from 1847 simply shows Jesmond as a number of fields! The few black rectangles represent the only buildings at that time.
However, within 40 years, most of the southern area had been developed into a residential suburb and by 1910 the northern half had also been developed.

The land had been given over to the Corporation of Newcastle by the various landowners under Covenants. These restricted the sorts of use and buildings that they would permit on their land.
It was because of those Covenants that the area remained mainly residential throughout the 20th Century, with the few pubs in Jesmond being around the periphery.
