Just out of interest (to me anyway), here is the same section of map from the 1859 survey. Almost in the centre of the map is Rose House which is marked on the other map as Rowe's House. I think the latter is more likely it's real name as it could well be the dwelling of William Rowe a notable shipbuilder from 1756 to 1810.
Hawthorn Leslie covers the area shown as Peter's Dock, the land having been purchased in 1870. It was formerly the yard of T & W Smith and (the other) Tyne Iron Shipbuilding Co.
To the left of Peter's Dock is marked an "Iron Shpbuilding Yard". I think this is the yard of John Rogerson & Co. John Rogerson was a prime mover of the Tyne General Ferry Co and many of the ferries were built at his yard.
