21 Moorfield sits proudly above a new ticket hall for the Elizabeth Line. Incorporating new pedestrianised streets, squares, walkways and an extended bridge to the Barbican; the development is suspended over a complex train interchange using a steel bridge structure. The building more than doubles the previous capacity of this key site, providing exemplary workspace for some of the additional 1.5 million people that, thanks to the new Elizabeth Line, are now within 50 minutes of central London. The development is designed in line with the City’s urban greening initiative to create an oasis on top of a station where one would not necessarily expect it: a vibrant mix of public spaces has been created, linking the Barbican to Moorfields, with over 20% of the site area devoted to bio-diverse habitats. An improved route for the Barbican Highwalk also creates a direct sightline from the Barbican to the newly pedestrianised Moorfields via a safe and accessible extended bridge and escalators.
