Major refurbishment of Gresham St Paul’s completes

Waterman is delighted that the refurbishment of Gresham St Paul’s, formerly known as Garrard House, has achieved practical completion. Designed by Wilkinson Eyre for AFIAA and Stanhope Plc, the new facility provides high-quality office space in the heart of London’s financial district.

Initially completed in 1998, the building was designed for Swiss company, Schroders, becoming their investment banking world headquarters. Original developer, Stanhope, returned to the scheme to lead the redevelopment with Waterman also invited to work on the project having delivered the original building’s structural design, but this time with our role extended to cover Building Services, Acoustics and Environmental disciplines.

Following the low carbon sustainable deep retrofit of the ninety’s office building, Gresham St. Paul’s provides 165,000 sq. ft. of Grade-A office and retail space, over ten floors and a basement level. As part of the projects drive to enhance wellbeing, large terraces have been created on the top three floors to provide access to expansive views, allowing tenants to look out over St. Paul’s Cathedral and the City of London.

The design was focused on creating a sustainable building for the future, and our structural engineers prioritised the retention of as much of the existing structure as possible. As part of the redevelopment, the top two existing floors were rebuilt with a lightweight structure to facilitate the creation of a new office floor at Level 9 and roof plant area above. The central core structure has been totally remodelled to reconfigure the stairs, increase WC provision and accommodate two additional lifts as part of the increase in specification for the development. The atrium was infilled to create open, flexible office space reflecting modern occupier requirements. This dynamic space gives tenants a range of informal areas which greatly enhance user experience, providing a massive boost to wellbeing.

Our building services team provided the new MEP design, which was tailored to meet the requirements of a broad variety of tenants. MEP services are divided between the basement and the new roof plant space, creating space for the new cycle parking and changing facilities in the basement. The design provides facilities for on-floor break-out and kitchen areas, adaptable lighting and user responsive air-conditioning systems.

The new energy efficient MEP systems replace the original outdated building services systems entirely, cutting carbon emissions by 25%. The design introduced other environmental initiatives into the scheme including a brown roof for ecological enhancement and rainwater harvesting to reduce water consumption. The building’s exceptional performance is reflected in its WiredScore ‘Platinum’ and BREEAM ‘Excellent’ ratings.

Tenants of the completed facility will further benefit from a reception area and business lounge. A ground floor café has also been incorporated into the design which is available for public use. Gresham Street enjoys privileged access to green spaces and public areas, offering moments of relaxation and enjoyment for tenants.

Financial and professional services firm, Smith & Williamson, will be relocating from their existing office to take advantage of the new state-of-the-art facilities at Gresham St Paul’s taking over six floors. The remaining upper floor offices have been let to independent institutional stockbroker and corporate advisor, Numis.

Mark Terndrup, Waterman’s Managing Director for Building Services South, commented: “This scheme demonstrates how, with intelligent design, it’s possible to take an outdated building and totally transform it into a modern cutting-edge workplace without the embodied carbon penalties associated with demolition and rebuild. Through the creation of amazing spaces and the much-improved building specification, the design has really delivered on its promises and the success of the scheme has been rubber stamped by the high-profile tenants taking occupation.”
