A Piece of History
St Marks Coptic Church is one of Kensington’s most iconic structures, having been in place since 1863. As Principal Contractor, Knowles’ were responsible for the entirety of the basement excavation, which sat beneath the full footprint of the church ground floor. With the need for the daily church services to continue throughout the duration of the excavation, methodical programming was required to ensure minimal impact on the timing of delivery. Careful sequencing was required across the project due to varying loads of the superstructure, including the church’s tower.
The complexities of this project provided an opportunity for Knowles to apply all the in-house skills of our team.
