ISG has secured a circa £30 million project with global investment firm Blackstone to remodel and refurbish floors one to six of the iconic Art Deco Adelphi Building, which overlooks the Victoria Embankment in London.
ISG will deliver approximately 190,000 sq ft of high specification Cat A open plan office accommodation across the six floors of the Grade II listed Adelphi Building, which will be part occupied during the project. The scheme incorporates significant structural alterations to upgrade and sensitively modernise the building, including the reinstatement of internal light wells to maximise the volume of natural light entering the structure at lower levels.
As the upper half of the building will remain in occupation during the project, ISG will systematically replace all 10 existing lifts and introduce a further two lifts, while maintaining continuity of services to remaining tenants. The main reception area will be remodelled and new entrances introduced at levels one and three to enhance accessibility. Perimeter light wells at level three will be opened out to further increase natural light levels within the building and the project includes a major element of public realm improvement work, with new pedestrian areas and attractive hard and soft landscaping.
The Adelphi Building steps in at level six, and at this point ISG will create a new landscaped roof terrace area overlooking the reinstated glazed light wells. Externally, the building’s existing smoked glass windows will be replaced with high performance clear glass units. The project is scheduled for completion in summer 2015.
ISG has worked across a diverse range of projects for Blackstone over a ten year period, including commercial office, light industrial, leisure and student accommodation schemes. In 2010, ISG successfully delivered the tallest student accommodation building in the world for Blackstone – the 33-storey, £120 million Nido Spitalfields development in London.
Alan McCarthy-Wyper, managing director of ISG’s Construction business, commented:
“We are once again delighted to be supporting Blackstone across its extensive property portfolio, delivering a high quality and efficient refurbishment solution to comprehensively modernise facilities at the Adelphi Building in London’s West End. With the building part-occupied, in a busy central location and historically significant, the project encompasses a raft of challenges requiring a real breadth and depth of technical experience and effective implementation.
“Early engagement is central to this project and by deploying a highly experienced delivery team from the outset, Blackstone has maximised the benefit of our pre-construction and enabling works expertise. This collaborative approach at an early stage in the process has proved vital in developing the design and scope of the project, generating important cost and programme efficiencies.”
