London Borough of Kensington and Chelsea
The existing site consisted of three blocks built in the early 20th century, each using different variations of the Considére system of reinforced concrete developed in France.
• A single storey roof extension has been constructed on each of the three office blocks in addition to a 4-storey side extension to one of the blocks.
• The range of unusual forms of construction required rigorous research and investigation to help inform the structural strategy and to develop an appropriate and elegant solution.
• The existing superstructure and foundations were justified for the additional loads, omitting the need for any strengthening works.
• The team worked closely with the architect to meet client objectives, delivering a scheme which maximised internal office space and allowed existing office tenants to remain in-situ during construction.
