KSG Conservation Area
King's Stairs Gardens lies within the Edward III's Rotherhithe Conservation Area. Southwark Council's conservation area appraisal states that the park is one of the few green open spaces that fronts directly onto the river and hence has both a high amenity and important biodiversity habitat value. It notes that the exceptional river views and the number of large trees make a significant contribution to the character of the area which is adjacent to the St. Mary’s Rotherhithe conservation area. It also provides a continuous green infrastructure between the river and Southwark Park and the tree-lined streets linking the north and south of the borough.
Conservation area status gives King's Stairs Gardens a strong added layer of protection against any plans to encroach upon the park, the playground and the riverside walkway and cycle route. It also links the park with the historic King Edward III Manor House site, with the listed Angel pub and William Gaitskell House in Paradise Street, and with the heritage areas of Rotherhithe Village. Together these form an important and irreplaceable stretch of riverfront for all to enjoy.
The park has been recognised as a Site of Importance for Nature Conservation. It contributes to an unbroken green corridor from Surrey Quays to the Thames. King's Stairs Gardens has many mature trees and provides an important mix of habitats which is important to local wildlife.
