The above plan features on the centre pages of L. du Garde Peach's book about John Smedley. It shows that Smedley's Hydropathic Establishment was surrounded on several sides by land owned by other people: Job Knowles Esq. owned land below the Hydro, down the Bank to the south; Wolley Hurt Esq. owned property adjacent to the western and south western boundaries; property next to part of the north western boundary was owned by Mr. Joseph Kaye and Mr. Jacob Gregory. The road we know today as Smedley Street was called Broome Head Lane and Bank Road, then Dob Lane, was extremely narrow.

After Smedley had died things changed at the hydro and the Directors of the Company that was formed in 1875 carried out a rapid building and expansion programme^[1].

Below are slightly larger versions of both the plan and the drawing of the hydro as it then was. Both of them show the main buildings with the Promenade in front and Mr. Smedley's Chapel to the left. There is more about the Chapel.
