The stunning project will upgrade the existing high-quality building with targeted interventions to extend its operational life and meet today’s expectations for flexible and adaptable office space.
This mixed-use development, designed by MacCormac Jamieson & Pritchard, is part of a cluster of buildings within Paternoster Square. Having originally been appointed by Mitsubishi Estates and Stanhope for the development of Warwick Court which was completed in 2002, we were delighted to reunite with the client for this exceptional refurbishment.
Working alongside Fletcher Priest Architects to sensitively update the building design, our specialists are providing mechanical and electrical, structural and sustainability input. The principal office entrance from Paternoster Square is remodelled under the works to provide a generous and welcoming space and the entire ground floor is transformed to provide an attractive frontage with a mix of retail uses. Infilling the existing atrium on levels 2, 3 and 4 will improve access to the floorplates from the core, whilst increasing office NIA, and the remodelling works allow the building to accommodate multiple occupiers over the 16,700 sqm NIA of office space with new internal finishes and shell and core provisions.
Wellness plays a key role in this refurbishment, seeing two existing roof areas on level 6 and level 8 converted into high quality external amenity terraces from which occupants can enjoy the close proximity to St Paul’s Cathedral.
The project’s sustainability strategy is structured around six key priority areas: energy minimisation, circular economy, biodiversity integration, health and well-being, water resources and responsible sourcing, and the full replacement of the MEP engineering systems will bring the building performance fully up to date.
Key enhancements to reduce Operational Carbon will include new high efficiency chillers, new air handling units with high efficiency heat recovery and integral air source heat pump technology, as well as CO2 heat pumps for energy efficient domestic hot water generation. With new LED lighting installed throughout the building, including perimeter daylight dimming and presence detection, the carbon emissions will be cut significantly. The development is predicted to achieve approximately 44% improvement over pre refurbishment carbon emissions.
