Shackerley’s SureClad® Modular Solution at Gresham St Paul’s

Shackerley’s SureClad® Modular Solution at Gresham St Paul’s

Shackerley’s SureClad® Engineered Stone ventilated cladding system has been used as a modular facade solution for a rooftop extension at prestige office development, Gresham St Paul’s, in central London.

The office building on Gresham Street has undergone a £50 million transformation, delivered by Mace and designed by leading architectural practice, Wilkinson Eyre. The project has maximised the building’s net internal area with an extensive remodelling programme, and added a three-storey extension at roof level.

The existing Portland stone facade has been retained and simplified with aluminium in-fill panels, and the architect needed to find a cladding material for the additional storeys that would reference the materiality of the existing building and answer planning requirements. The cladding system for the new storeys also had to work within the loading parameters of the original structure and offer a viable solution for the buildability challenges of working at height on a confined site in the City. Shackerley’s SureClad® Engineered Stone ventilated cladding system answered all of these requirements and was installed as pre-fabricated modules, following close collaboration between Shackerley, and Austrian facade specialist, GIG Fassaden.

The Wilkinson Eyre team considered a number of alternative cladding systems and materials to find a close aesthetic match for Portland stone that would meet planning requirements and weight restrictions for the project. Each potential solution was assessed against a series of criteria; look and feel, cost, fire safety, weathering, green credentials and mechanical suitability. The design team also considered a number of reference projects, including Axtell House, an office building in Soho where Shackerley’s SureClad® Engineered Stone system was used for the facades of additional storeys to co-ordinate with the Portland stone of the original building.

The Shackerley SureClad® Engineered Stone facade system was specified in a creamy beige Valpolicella colourway with white variegation and a sandblasted finish, complementing the existing Portland Stone facade.

The facades were installed as a modular system and, working closely with GIG Fassaden, Shackerley fabricated 400 modular facade units at one of the company’s ISO 9001-accredited factories in Lancashire. The custom-designed modular units utilised Shackerley’s large format 3050 x 1240mm x 30mm SureClad® panels with Shackerley’s tried and tested under-cut anchor and bolt fixing system, with each pre-fabricated facade section delivered to site as an installation-ready module that could be craned into position and secured in place.

Gresham St Paul’s adds to Shackerley’s portfolio of projects where the SureClad® system has provided a lightweight and robust solution for the facades of additional storeys, complementing the existing facade material.

Shackerley’s SureClad® engineered stone cladding provides the ideal alternative to GRC cladding

For projects that require look a natural stone facade or GRC cladding with large format stone cladding panel sizes, Shackerley’s SureClad® engineered stone cladding system is the ideal choice. Shackerley’s SureClad® engineered stone facade system is agglomerated stone cladding system. Unlike a GRC facade, Shackerley’s SureClad® engineered stone cladding system is reconstituted stone cladding with zero cement content and very low resin levels.

Our engineered stone facades are sometime called technical stone cladding panels and are manufactured by Shackerley to provide an installation-ready, lightweight cladding engineered stone rainscreen. Our large format cladding panels are manufactured with undercut anchors for a mechanical fixed cladding solution that is secure and suitable for any engineered stone facade design requirement.

Our mechanical fixed facades mean each panel is secured with secret fix undercut anchors and our engineered stone rainscreen is produced under factory conditions to achieve the correct stone facade windload requirements

Our large format facade panels usually mean our engineered stone facades span floor to floor on larger high-rise buildings.

Engineered stone is a SureClad® product, which is an agglomerated stone facade with very low resin levels.

Shackerley’s SureClad® engineered stone cladding answers the non-combustible cladding requirements of BS EN13501-1. Our engineered stone facade system is an A2 S1 D0 rated non-combustible facade to BS EN 13501-1.
