135 Bishopsgate, London, UK

Project Overview

Completed in 2020, 135 Bishopsgate is a flagship commercial refurbishment forming part of British Land’s £1bn transformation of London’s Broadgate Campus. Originally designed by SOM in the 1980s, the 13-storey structure was reconfigured to deliver 325,000 sq ft of high-spec office and retail accommodation, with a strong emphasis on sustainability and occupant wellbeing.

In line with British Land’s low-carbon ambitions, Fletcher Priest Architects retained 90% of the existing structure and envelope to reduce the embodied carbon impact of the build. The sensitive architectural intervention enhanced the building’s thermal performance and air circulation, while upgrading the HVAC systems allowed for the creation of garden terraces – improving access to outdoor space and amenity for tenants.

Mechanical and electrical packages were delivered by Gratte Brothers, including full fire protection systems, rising busbars, chillers, air handling units, and building management systems. To enable safe access across multiple floor zones during construction, Dura Composites was appointed to supply and install its GRP riser flooring system.

Safe Access with Immediate Void Protection

Dura’s GRP riser system comprised moulded anti-slip grating supported by a galvanised steel frame. Installed by Dura’s Operations Services team, the solution provided permanent void coverage and fall protection from day one – allowing other trades to work confidently without the need for temporary platforms or edge protection.

Non-conductive, corrosion-resistant and fire retardant, the riser panels were easily cut on-site to accommodate service penetrations. Their lightweight nature made them simple to manoeuvre and install, helping to speed up programme delivery and improve coordination with the M&E schedule.

Recognised for Safety and Sustainability

Gratte Brothers’ Project Team at 135 Bishopsgate was awarded an International Safety Award with Merit from the British Safety Council in recognition of their proactive approach to site safety throughout the delivery phase.

The project was also shortlisted for the 2022 RIBA London Award, reflecting both the architectural quality of the transformation and the collaborative efforts to prioritise sustainability and user experience. Dura’s riser system played a key role in supporting safe, efficient construction on this complex, multi-level site.

Delivering high-profile projects like 135 Bishopsgate requires complete confidence in the safety and performance of every system used on site. The riser system from Dura Composites is a reliable and effective solution that helped maintain a strong health and safety culture throughout the project.
