Proposals by Piercy & Company would double size of space at existing 1980s block

Five firms have been sounded out about the latest proposals by British Land at its ongoing makeover of its Broadgate campus.

Sir Robert McAlpine has worked on four schemes under its 10 year Broadgate Framework, which it signed in 2015, including 100 Liverpool Street, 135 Bishopsgate and 1 Broadgate.

McAlpine is already on site with AHMM’s 1 Broadgate, worth around £300m, and is expected to start on site later this year with a tower at 2 Finsbury Avenue designed by Danish practice 3XN.

Piercy & Co’s 1 Appold Street proposals

The latest deal at the City of London site is called 1 Appold Street and is set to be competitively tendered rather than let through the framework.

As well as McAlpine, the other firms that have been contacted about the job are Lendlease, Skanska, Mace and Multiplex.

It is understood the job has a construction value of around £220m and is likely to see three bidders shortlisted by the summer with a PCSA award made towards the end of the year.

Designed by Piercy & Company, the work will involve retaining 75% of the existing 1980s office building, stripping it back to its core and extending  it upwards by five floors to make 13 storeys.

As well as adding extra storeys to the current structure, the practice’s plans extend the building’s floorplates closer to the site perimeter. Under the proposals, balconies would be provided on the new building’s eastern façade and there would also be a rooftop pavilion and terrace.

British Land’s team includes project manager Opera, quantity surveyor Core 5, AKTII as structural and façade engineer, and DSDHA as landscape architect.

The current building was designed by Skidmore, Owings & Merrill and backs on to the grade II-listed Liverpool Street Station shed and the Exchange Square outdoor area which includes another 1980s office building, One Exchange Square, that is also due for a makeover by investor developer LaSalle under plans drawn up by Fletcher Priest.
