ISG wins £59m London office refurb

Contractor ISG has secured a £59m project to carry out a major office refurbishment opposite the criminal courts in London’s Old Bailey.

The client is asset management firm Blackstone, for whom ISG has previously worked on the Adelphi Building and One American Square.

ISG will start work at 20 Old Bailey in November 2015. A new façade, with stone, aluminium and glazed architectural treatments, will be erected to transform the external appearance of the property and two additional floors will be added on top (as shown in the image below). The building upgrade includes extensive structural alterations and internal remodelling to provide approximately 240,000 sq ft of office accommodation.

Remodelling includes infilling the existing square atrium in the centre of the building and creating a new, larger, rectangular atrium towards the front of the building. The new atrium will also extend downwards to ground floor level to maximise the volume of natural light entering the reconfigured building.

To further unify accommodation at 20 Old Bailey and create additional capacity at the sixth, seventh and eighth floors, ISG will extend these stepped back floor plates in line with the new façade. ISG will relocate and form a new main core, infilling two existing cores, a staircase and service risers to create more spacious open floor plates at all levels. The steel frame roof extension will be stepped back from the main façade and incorporate balcony structures across the two new levels. The project also includes remodelling three existing basement floors to provide cycle storage, changing, shower and locker facilities.

ISG regional managing director Stuart Deverill said: “Blackstone has an enviable pedigree for acquiring underperforming property assets in prime London locations and re-positioning the space to create highly-desirable commercial office space. This highly specialised and logistically complex project plays to our significant strengths delivering central London heavy office refurbishment schemes and underlines our commitment to forging strong relationships and working in partnership with our existing customer base.”

ISG chief executive David Lawther said: “Global demand for prime office space in London’s most desirable business locations continues to drive this buoyant market. We are pleased to be able to continue supporting our core customers with their refurbishment programs.”
