Interior Services Group (ISG) has secured a £52m contract from Japan-based Kato Kagaku to refurbish Bush House, the former headquarters of the BBC World Service in central London, UK.
Upon completion, the four-building commercial office scheme will be renamed as the Aldwych Quarter.
Under the deal, ISG will deliver more than 300,000ft² of office accommodation across the four buildings and central courtyard with under-croft that make up the development.
ISG will strip out the buildings to shell and core, upgrade and modernise the internal space, install new mechanical and electrical services, replace 14 of the existing lifts and deliver an additional lift to improve accessibility.
Out of the four buildings, three are expected to secure a BREEAM Excellent environmental performance rating, with sustainable enhancements via improved insulation and services installation.
The contract will see ISG re-roof all four buildings, clean the façades, carry out masonry repairs and replace a number of windows as part of an external envelope package of works.
The company will also clean, repair and preserve various architecturally listed elements including the Bush House portico, staircases and lobby areas.
ISG will reconfigure and rationalise space across all four buildings to create an open plan office layout.
The Cat A fit out includes the installation of raised access floors and suspended ceilings, four new reception areas, and new cycle facilities and toilets.
ISG said the programme has been carefully designed to allow the phased handover of accommodation, enabling the marketing agent, Jones Lang LaSalle, to provide potential tenants with flexible occupation scenarios.
ISG Fit Out managing director Paul Cossell said a key factor in securing the refurbishment contract was its flexible delivery programme, which provides a significant reduction in project duration.
"Our phased handover strategy allows earlier than anticipated occupation of key areas of the development, providing an attractive potential revenue boost for our client," Cossell said.
