Inside the deal: The £73 million contract is on behalf of the City of London Corporation and Mace, who announced the deal in February.  

The Salisbury Square development will see the new City of London Law Courts and City of London Police headquarters built in the Square Mile. 

It will house a flagship legal facility for His Majesty’s Courts and Tribunals Service (HMCTS) and a state-of-the-art base for the police.    

The court will have 18 courtrooms in total, focusing on high-level fraud, cyber and economic crime.  

A new commercial building and public realm is also planned.

Structural package 

Circular construction techniques are being used by Keltbray, following a £10 million demolition and enabling works package.  

Work will now include the complex installation of more than 500 king post piles, secant piles, contig piles and bearing piles; construction of a new basement slab, core base and box, as well as four new cores; the formation of a reinforced concrete superstructure for the court building and a ‘listed building’ soft strip using ‘cut and carve’ techniques to retain key elements of the heritage structure. 

Completion is scheduled for 2026.
