St Peter’s College is an independent Reception to Year 12 college for boys. Located in the inner -city suburb of Hackney, the college chose to redevelop its under-utilised heritage-listed 1935 built Pentreath building into a new middle school within its senior campus. A substantial two storey addition, designed to optimise its passive environmental performance, was then built.

Project Detail

The existing Pentreath building had to be carefully stripped and then restored, with multiple wings connected to the building also demolished. A new two storey addition with a floor area greater than the existing building was added.

Construction Detail

  • Precast concrete
  • Large glazed sections
  • Deltacore flooring


  • The building had to be complete and ready for use on the first day of the 2016 school year. There was no flexibility to extend what was already a shortened construction period.
  • Large quantities of Asbestos was found in the existing ceiling space- it had not been identified previously ¬†and was not factored into the building program or contract.
  • The existing building structure had some shortcuts in its construction that had to be rectified as part of the redevelopment.


Despite the heavy impact the discovery of asbestos and latent engineering issues had on our construction program, Kennett Builders were able to complete the project ahead of schedule.
