Atenor acquired Fleet House in April to deliver its first project in London.
The seven storey building is located on New Bridge Street near Blackfriars Station and within the Fleet Street Conservation Area.
Architect HOK has designed the building overhaul, which retains 80% of the existing structure and features a planted façade.
As part of the revamp an extra floor will be added to the building which is targeting BREEAM ‘Outstanding.
The project includes a new public passageway, Bridewell Passage, to improve access to nearby Bridewell Theatre and St. Bride’s Church and allow on site servicing.
The interior will support employee health and well-being, maximise daylight and views and provide flexible, modern workplace.
“The opportunity to reposition Fleet House aligns with our mission to bring Atenor’s track-record to London and provide with it a leading-edge occupier experience which is sustainable, aesthetically pleasing and focused on user well-being,” said Eoin Conroy, Country Director UK, Atenor.
