• Resumen

  • Designed by PLP Architecture, 22 Bishopsgate rises above its neighbours, redefi ning London’s skyline (Figure 1). At 62 storeys and 278m, it is the secondtallest building in the city. The design process begun in 2012 with the goal of creating 30% more lettable area than its predecessor. The challenge was to do it in the quickest and most effi cient manner.

    The building was erected on the site of an abandoned project, reusing 100% of the existing foundations from three previous buildings, and incorporating more than 50% of the basement built for its predecessor (the Pinnacle). Building on such a constrained site – surrounded by narrow streets, tall buildings and other valuable heritage – also brought engineering and logistical challenges that pushed the limits of our creativity.

    This article describes the approach to reusing the existing foundations and basement, as well as the focus on material effi ciency in designing the superstructure and transfer structures.
