Project Description

HMP Wandsworth was originally constructed in 1851. Because of its age and constraints to its aesthetical appearance, a sympathetic and thoughtful approach was undertaken during the Rotundas re-roofing and refurbishment works. Works involved the complete re-roofing of the Rotunda and Lantern Light Roofs including any structural timber repairs. The old slate roof was replaced by composite insulation boards with a Terne Coated Stainless Steel sheet covering giving a thermally efficient, maintenance free roof with an expected 50 year life span. The Shaylor design team brain stormed a unique solution which entailed the installation of a working platform with integral waterproof barrier fixed to the internal brickwork upstands to the roof lantern.   During evenings temporary access was provided and over a number of nights a scaffold platform was erected to the lower section of the roof. Then external access scaffold was installed to provide safe and uninterrupted access to the roof areas. A Sarnafil roof membrane installed over the scaffold platform to allow works above to proceed, and an internal and external access walkway was installed for future maintenance.


"Shaylor Group are an excellent company to work with, and throughout the project health and safety was managed extremely well. It was a pleasure working with Shaylor Group on HMP Wandsworth."
