The dense urban location made this project a tricky piece of infrastructure to thread into its surroundings, with work having to squeeze in between existing buildings. Layers of history had to be revealed before work could get underway with almost 100,000 square metres of excavated material removed from the site.

New entrances and ticket halls at both Liverpool Street and Moorgate relieve congestion and provide step-free access and seamless interchanges for everyone who lives, works, and travels through the area.

New forecourts and plazas have been created around the entrances, with wider pavements, trees, and seating, for some of the 200,000 people passing through the station each day to meet and mingle.

The entrance into the eastern ticket hall is through a striking, glazed canopy located in a new public space at Broadgate. Natural light filters below ground during the day, while at night the canopy acts as a lantern with light shining out of the glazed entrance. The western ticket hall is at street level and accessed through an angular portal, framed by bold blue coloured glass.

Keeping Moorgate and Liverpool Street station operational throughout construction was a challenge, which was achieved by utilising prefabricated concrete building components including precast concrete soffits and columns at the Moorgate and Broadgate entrances. Offsite development and construction ensured higher levels of quality assurance and standardisation of precast modules, and vastly reduced construction time on site.
