The former 175 Bishopsgate project, now known as One Exchange Square, is being delivered for real estate manager LaSalle Investment Management on behalf of Malaysian investor Permodalan Nasional Berhad.

(R-L) Existing SOM designed 1980s building and new greener design by Fletcher Priest

Designed by Fletcher Priest Architects, the 13-storey scheme will comprise 430,000 sq ft of workspace and 17,000 sq ft of retail, fronting both Bishopsgate and the newly re-landscaped park at Exchange Square.

Multiplex is understood to have beaten rival bidders Lendlease and Skanska to take the job, which will involve retaining 90% of the existing structure.

This will mean the resulting asset will have 50% lower embodied carbon than a typical new build office of comparable size, saving approximately 7,600 tonnes of CO2e compared to the Greater London Authority 2030 target.

The project is 100% electric, using intelligent façade design and mechanical services twinned with building management systems to manage operational energy use.

Design features impressive expressed structural steelwork on Exchange Square elevation

With 13 upper floors and floorplates averaging 40,000 sq ft, the building features landscaped terraces on every floor, totalling 33,000 sq ft across the building.

In addition to boasting a striking feature reception and 8,000 sq ft amenity lounge, One Exchange Square benefits from outstanding transport connections and a diverse array of amenities, conveniently situated just a one-minute walk from Liverpool Street Station and surrounded by vibrant locations such as Broadgate Campus, Spitalfields, Shoreditch and the City of London.
