The ‘deep retrofit’ of Fleet House was first granted planning consent by the City of London in January 2023, but was resubmitted in 2024 to increase the proposed buildings height from eight to nine stories and remodel the top floors to create new spaces for both occupiers and the public.

Drawn up for Brussels-based developer Atenor, the scheme takes a fabric-first, low-carbon approach which retains 73 per cent of the existing structure while adding a further 3,428m² of space.

The latest designs will see the creation of a 162m2 south-facing roof terrace and garden at the top of the building, which will be publicly accessible outside office hours, with views towards St Bride’s Church, St Paul’s Cathedral, the Palace of Westminster and across the wider City.

The revisions to the original consented scheme were made in response to ‘shifting market conditions and construction cost pressures’, according to planning consultant Lichfields.

The development will involve the demolition of the 1950s St Bride’s Tavern pub, which is currently unoccupied.

The pub, behind the block at 8-12 New Bridge Street, had already been earmarked for demolition in previously consented plans by Pringle Brandon Perkins + Will in 2014. That unrealised £20 million scheme would have seen both buildings replaced by all-new structures.

A ‘re-provided public house’ on the ground floor and part-basement level are included in the plans. The application also features a new pedestrian priority route connecting Bride Lane and Bridewell Place.

Ian Anderson, senior director at Lichfields, said: ‘With a number of City office schemes being revisited or delayed, the priority here was to secure a permission that could actually be built, while improving what the development gives back to the City.

‘By working closely with Atenor and the City of London Corporation, we’ve shown that a deep-retrofit scheme can respond to viability pressures, respect heritage sensitivities and still raise the bar on public access, sustainability and design quality.’

A new ‘pocket park’ will also be created within the improved public realm Bridewell Place, alongside with a ‘dynamic public art installation’ in Bridewell Passage.

Since the initial consent for the scheme in 2023, Gensler’s 10 storey, 100 New Bridge office building has been consented in a plot directly opposite the site of Fleet House. HOK argued that the new office block justified the extension of Fleet House by one storey, as views of of St Paul’s Cathedral would now be partly obscured in the original proposal.
