Refurbishment is set to begin on Helical’s 100 New Bridge Street office scheme, located between Farringdon and Blackfriars stations.

Helical revealed today that the City of London is finalising its desicison to grant planning permission for the scheme. 

The scheme is worth £100 million and it is understood that Mace will lead construction, with Keltbray carrying out demolition, according to Construction Enquirer

Inside the scheme 

Gensler developed the design for the project, which aims to be BREEAM Outstanding building, and produce zero carbon in operation.

Mace will expand the almost 16,000 sqm site to nearly 18,000 sqm, with the addition of two new floors, making 12 floors in total. 

To ensure a Grade A office building, refurbishment works will include recladding the facades, technological upgrades, and providing tenant amenities.

Helical acquired the site in March 2022, and construction is expected to begin in Q4 2023 and complete by Q2 2025

Environmental efforts

Gensler’s plan aims to reuse a number of materials from the building, including:

  • Nearly 4,000 sqm of metal ceiling tiles that will be repurposed into new ceiling rafts.
  • More than 180 sqm of stone roof ballast that will be repurposed as a fireproof perimeter to the façade.

Cross-laminated timber (CLT) will be used for structural interventions where possible as an alternative to steel.

Farringdon latest

Another office-lead scheme is being developed at Holborn Viaduct near Farringdon by Multiplex

The project, worth between £150 million and £200 million, is being led by Royal London Asset Management (RLAM), and will see the full construction of a 34,300 sqm office building. 

Helical was approached for further information on the 100 New Bridge Street scheme.
