St. Bartholomew’s Hospital PPU

St. Bartholomew’s Hospital PPU

St Bartholomew's Hospital is an internationally renowned teaching hospital in the City of London. It is also the oldest hospital in Britain, and still occupies the site it was originally was built on where it has provided healthcare since 1123.

In 2005 the Trust embarked upon an extensive redevelopment programme using PFI funding to redevelop its estate. At the Barts site, the 20th Century buildings in the South East of the estate were replaced with the new hospital development, providing consolidated and modern clinical facilities. The first phase was opened in May 2010 and completed in 2016.

The Trust recognised strategic advantages for the establishment of a Private Patient Unit on the Barts site. This was achieved through consolidating the new clinical facilities with the existing range of specialist services, together with the prestige and reputation for excellence associated with St Barts.

Our Role

Ayesa were initially appointed by Nuffield Health as the Structural and Civil Engineers to develop feasibility and conceptual designs for the proposed adaption of a group of important historical buildings at St Bartholomew's Hospital in the City of London, to create new a Private Patients' Unit (PPU) hospital facilities. Our role continued throughout the detailed design and construction stages following our novation to Kier Construction Limited who were appointed as the principal contractor for the project.

The PPU works involved significant adaption to a group of three buildings, circa 1900, not required by the PFI development. Each of these redundant buildings had its own distinct form of construction. Through our intimate historic knowledge of the St Bartholomew’s Hospital site, and following our focused program of investigations, we provided sympathetic and economical structural alteration solutions required to accommodate the modern PPU facilities whilst retaining and restoring the historical Portland stone facades and the Giltspur Street “streetscape”.
