The 100 Liverpool Street project shortlisted for Stirling Prize

British Land's 100 Liverpool Street scheme has been shortlisted for The Stirling Prize, the UK's top architectural award.

In shortlisting the project, judges from the RIBA (Royal Institute of British Architects) praised the scheme for 'its approach to reusing the existing building demonstrates clear strategic thinking, keeping what could be salvaged, unpicking what could not, and adding what was necessary'.  

Judges added: "The client and design team evidently worked together very closely – adjusting and nudging the brief on the way to produce the best outcome, which is a truly impressive project."

We provided MEP, environmental and fire engineering solutions for the project, which achieved a BREEAM ‘Outstanding’ rating and is British Land’s first net zero carbon development. 

Six projects were shortlisted for the prize, with a winner due to be announced in October.

Below are just some of the key features of our work on the project, but for more information , or to talk about how we could help your net zero ambitions, please email

Early technical advice

  • Our in-house Technical Advisory Group (TAG), were involved from the project outset, offering design and project guidance and helping to negotiate the upgrade of existing UKPN HV supply from 4MVA to 6.5MVA, which was crucial for the viability of the development.

  • TAG, which has influenced positive outcomes on many of our projects, also provided specialist knowledge in high-voltage design by working closely with the project team to develop the strategy for the development.

MEP solutions

  • A major point for the project was getting the ‘top-down’ MEP strategy agreed, with all the plant placed on the roof. By solving the logistical problems of craning and maintaining equipment on the roof, we allowed the retail space at ground level to be maximised – increasing further the viability of the scheme.

  • Because of the complexity of working on the site with so many stakeholders – including Network Rail, Crossrail and TfL – our MEP team also helped devise a strategy for networking distribution between the office levels and basement.

Smart Enabled

  • The smart enabled building, with all the infrastructure, building management system in place, has allowed tenants to take advantage of new technology now and in the future. 

Fire engineering

  • Our advanced fire engineering strategy identified three areas for improvement for the scheme and the resulting changes, which were all accepted by the client and relevant authorities, resulted in sizable savings in cost and schedule.

Environmental solutions

  • The scheme achieved BREEAM Outstanding, with the necessary reduction in CO2 emissions met by the efficient thermal envelope design and building services equipment efficiencies.

  • The roof houses an array of PV, reducing the carbon footprint further, while a ‘grey’ and rain-water system was used with extra filtration on the air conditioning system.
