50 Fenchurch Street was given planning more than three years ago

Mace and Multiplex are among the firms preparing to bid for the chance to build a new tower in the City of London designed by Eric Parry.

The 35-storey scheme at 50 Fenchurch Street was the first by Square Mile planners to be approved at a virtual meeting when it was given the green light in May 2020 at the height of the first covid-19 lockdown.

Building understands prequalification for the job, believed to be worth £400m, has begun with a shortlist of bidders due to be drawn up by Christmas.

50 Fenchurch Street will include a vertical green wall

Other firms thought to have run the rule over the work include Lendlease although one source said: “Lendlease are pretty busy with their own [development] stuff at Euston so we don’t know about them.”

Development manager on the job is Yard Nine, while the project manager is Third London Wall with Core Five the QS. Arup is the consultant on M&E and structures.

Yard Nine was set up in 2017 and was behind Fifty Paddington, a £50m office block opposite the train station built by McLaren, and 80 Fenchurch Street, the new home of Arcadis, which was built by Skanska.

The 50 Fenchurch Street scheme, opposite Parry’s 120 Fenchurch Street and a couple of blocks from his rejigged 1 Undershaft project, will provide a new home for the 500-year-old City livery company, the Clothworkers’ Company.

The 150m tall project would involve the demolition of the existing 1950s livery hall, designed by Herbert Austen Hall and refurbished by Donald Insall in the 1980s.

It will include a replacement underground livery hall topped by retail and 78,000 sq m of office space, a public roof garden and winter garden and a new public space based around a restored grade I church tower.

Work will involve restoring various heritage assets close by, including a grade I listed church tower

The grade I tower, the Tower of All Hallows Staining, which was built around 1320, and the grade II Lambe’s Chapel Crypt, which dates from 1200, will both be restored under the plans.

The tower will incorporate a vertical green wall, bespoke ceramic cladding at ground level, a glazed podium and crafted glass detailing on the upper levels.

The scheme is currently slated to complete in the first quarter of 2028.

Historic Royal Palaces was among the heritage groups to voice opposition to the proposal because of its impact on the setting of the Tower of London which it manages.
