Project Detail

Located next door to the world-famous Claridge’s Hotel in the exclusive Mayfair area of London, 43 Book Street was formerly two historic Georgian Houses dating back to 1725, which were remodelled as one property in the 1900s. The brief was to turn the existing office building into five luxury, high-end self-contained apartments for use by guests of the adjoining Claridges Hotel. With the building’s status as a Grade II listed building, all alterations and new construction elements needed to match the style of existing features to keep with the Georgian-period style.

The project involved demolitions and structural alterations to existing structures, including the roof, with reconstruction to a higher level to follow. Additionally, the removal of stairs and passenger lifts from the interior of the building took place, which were replaced with new staircases and accessibility ramps. Temporary waterproofing was required in certain areas of the building before roof works could take place. The alterations to the roof also needed an ‘over-roof’ scaffold with supports from the ground level.

Due to the project’s location being in busy central London, a comprehensive Construction Phase Plan was required to ensure any vibrations, sound, and dust did not impact the nearby residents. As the adjacent Claridges hotel remained in operation throughout the project, it was also essential that any construction works undertaken did not disrupt the operations of the hotel and the guests within.

A Traffic Management Plan was needed to account for central London traffic. In addition, our team also needed to be aware of the nearby businesses and resident access needs, so it was essential that all staff vehicles, deliveries and plant item arrivals were carefully monitored, controlled and guided to ensure minimal disruption to the area.

Due to the timing of the project, measures were also taken to navigate COVID-19 and global material shortages to accommodate for partial
site closures and rising costs for materials.
