And now - design....
Stonebridge Lock house (1860) was a unique design
LMA ACC 2423/P906
Although Hardmead Lock house, built in 1876, had the external appearance of the later 1878 design, the internal layout was different, with a central staircase rising from 3 feet inside the front door, effectively dividing the house in two.
Rammey Marsh Lock house (1877) also had this central staircase.
LMA ACC 2423/026
The most popular design (1878) was used at seven locks. The staircase in these houses climbed transversely up the back wall, some from the right hand side and some from the left. It seems to depend which side of the Navigation the house was built. Hertford and Feildes Weir (on the east bank) are both right handed whereas Dobbs Weir, Tottenham, Waltham Town were/are left handed. The long-gone houses at Picketts and Ponders End, also on the western side were almost certainly left handed as well.
LMA ACC 2423/P016
Kings Weir and Ware Weir (1886) both used the same design
LMA ACC 2423/P025
The Waltham Common house (1893) and that at Stanstead Lock (1899) used the same set of drawings with "Stanstead" pasted over "Waltham Common.
LMA ACC 2423/P044
Aqueduct Lock (1895) - there are no plans of the house here except the outline on the 1922 lock rebuilding drawing. This shows that the building here was probably built to the same design as Waltham Common and Stanstead
Cheshunt lock house (1909) seemed to incorporate bits of most of the previous designs
LMA ACC 2423/P40
Whereas Carthagena lock house (1936) was, unsurprisingly, a new layout altogether.
LMA ACC 2423/P2674
