Holborn Viaduct, London

Project Description:


The demolition of three buildings and the construction of a 34,300sqm office building across thirteen storeys. Located at the intersection of Holborn Viaduct and Farringdon Street, the new building is shaped to enhance the setting of the listed south-eastern gatehouse, one of four which frame the Holborn Viaduct bridge. Portland Stone, reused from the existing buildings, will form a new masonry base on Farringdon Street and weave the gatehouse back into the streetscape.


The existing street level alignment accommodates two main building entrances. One from Farringdon Street (level 00) and one from Holborn Viaduct (level 02). The entry lobbies are connected to each other internally via an accommodation stair and lift. A third entry into the building is via the Wellness Wing amenities in the southern part of the site. This entrance is dedicated for cycle users of the building and is conveniently located directly off of Farringdon Street and its Cycleway no.6.


The typical office floor is arranged around a side core and an atrium void with interconnecting accommodation stairs and break-out spaces. Level 11 has two accessible terraces that provide outdoor space and views across London as does the rooftop pavilion floors (levels 11 & 12).


Two basement levels house the building's main plantroom areas, in addition to the on-floor air handling units and a minimised rooftop plant area.

Key Challenges:

  • Network Rail Interface

  • Landlocked development

  • Asbestos Remediation

  • Temporary Works retaining Holborn Viaduct

  • Party wall
