ISG wins £30 million Deloitte Building redevelopment

ISG has won a £30 million project to redevelop and extend an office building in London’s historic Midtown commercial district. The scheme, which is led by Endurance Land in partnership with Henderson Park, sees ISG add circa 10 percent lettable space to 66 Shoe Lane, whilst creating a high-quality, multi-tenanted contemporary space with a landscaped communal courtyard.

Half of the nine-storey,150,000 square ft building, has already been part pre-let by its previous incumbent tenant, Deloitte – enabling the multinational professional services business to expand its digital arm by the turn of the decade. Situated near to Crossrail’s Farringdon station, the new office space will attract tech-savvy professionals, as well as bringing in creative talent from nearby Clerkenwell.

Designed by London architect, Stiff+Trevillion, the refurbished building’s environmental performance will be enhanced to a BREEAM Excellent rating, with extensive remodelling at ground floor level to include two new entrance lobbies, and redesigned façade. ISG will demolish an eighth-floor steel frame extension and construct a two-storey steel structure, that extends across half of the building’s existing floorplate. External balconies will be installed on all floors, providing terrace space overlooking the central, landscaped courtyard.

Significant structural alterations will be made within the building to rationalise space and create a more contemporary floor plate configuration. The central core and atrium will be remodelled to include four additional lift shafts and will then be infilled to create a larger floor plate. To further extend the floor plate, a second full height atrium will also be infilled.

Focusing on programme efficiencies, ISG will simultaneously demolish the core and infill the existing atria – deploying a complex temporary works solution from roof to basement levels. The management of materials around the site has also proved a critical area for innovation, with an early decision to use spider cranes to eliminate the requirement for a tower crane and a corresponding review and redesign of the largest components coming onto site. Floors two to five will receive a Cat A fit out, with the remaining levels delivered to a shell and core finish.

Steven McGee, managing director of ISG’s Construction South business, explains:

“The opportunity to work in partnership with Endurance Land at an early stage and under a collaborative form of procurement has proved instrumental in our ability to innovate and reduce programme duration. Bringing our supply chain partners into the process at the earliest stages has given the wider team the opportunity to explore optimum solutions for key construction challenges with significant benefits to cost, programme and value-added measurements. This enlightened approach is highly desirable for complex projects, and more widely, it represents a high-performing template for all project procurement.”
