Welcome to the consultation website for the repositioning of 40 Holborn Viaduct, EC1N 2PB.

Nuveen is bringing forward plans to reposition and refurbish this site, which sits prominently at a gateway to the City of London. Our proposals will deliver high-quality, flexible office spaces; greater retail opportunities; enhanced public realm; and a new façade which will deliver an exemplary retrofit project to the area.

The development prioritises sustainability and is fully committed to significantly improving the building’s operational efficiency.

In addition, our proposals will positively respond to the Destination City ambitions of the City of London Corporation.

Here you can find out information on our proposals and get in touch with the project team, as well as providing any feedback you may have.

We have recently hosted two in-person events to discuss the proposals with the project team. These were held at St Andrew Holborn on:
– 12th June 2023, 16:00 -19:00
– 13th June 2023 , 11:00 – 14:00

The Site

Previously located outside the historic City walls, over time the City has spread to include Holborn Circus. 40 Holborn Viaduct now acts as a gateway for those arriving at the western entrance to The City of London.

40 Holborn Viaduct is currently a 9-storey (Ground +8) building with 3 additional basement levels below and a plant level above. It comprises predominantly commercial office space with some ground floor retail use.

This important site is worthy of an exemplary building that will welcome and enchant visitors; a building that reflects the City’s values and responds to the diversity of cultural and commercial opportunities in the area, which has recently included the emergence of Smithfield Market and the relocation of the Museum of London.

Current challenges with the site.
Over the last decade, numerous issues relating to design and materiality have arisen within the site, which mean the building is no longer watertight and has become increasingly dated and inefficient.

Such issues include:

  • Poor Operational Carbon, currently EPC D.
  • A water-stained façade appearance due to poor detailing and inappropriate stone selection.
  • The façade is defensive in character, inward looking, and sealed off from the public realm.
  • The building is not meeting the expectations of modern occupiers.
  • The building has limited wellness and amenity credentials.
  • There is a lack of external spaces, with no terraces or balconies and limited urban greening.
  • Poor entrance visibility with limited branding opportunities.

Our Vision

Our vision for the site is a sustainable and vibrant development, with high-quality office accommodation and amenity provisioning, generous urban greening, and active frontages which interact positively with the surrounding area.

Our emerging plans for the site include:

  • Prioritising sustainability – through the delivery of a fully electric building with improved operational efficiency.
  • Retaining Embodied Carbon – retaining approximately 70% of the existing building’s structure and, wherever possible, reusing materials onsite.
  • Improving appearance – acknowledging this sites significant location, we will create an urban marker which will help people to navigate through the area and into the City.
  • High-quality workplace accommodation – circa 180,000 sqft (NIA) of desirable high-quality, modern, and flexible workspace.
  • Increasing biodiversity – extensive urban greening on and around the site, introducing green balconies, landscaped terraces and significantly enhancing the existing pocket park.
  • Enhanced site activation – introducing new amenity spaces at the Ground and Lower Ground Levels which are flexible and accessible to building tenants and available on request to community groups.


Proposed Plans

Our proposal is designed to maximise the sites potential and make it viable for modern office standards and attractive to a wide range of tenants.

Key elements of our proposals are shared below and further details will be provided on Virtual Exhibition boards below, ahead of our in-person consultation events.

Our proposals involve removing the current façade and replacing it with a new, modern façade including a framework of balconies, opening up the building and introducing significant urban greening improvements to the site.

We will introduce two new floors and a smaller area of roof plant which step back towards the northeast, each including a landscaped terrace with views to the City.

We will reposition 40 Holborn Viaduct by achieving the highest sustainability credentials, targeting BREEAM Outstanding, Smart Building rating, EPC rating A, Nabers 5.5*.

Approximately 70% of the existing building is to be retained.

The building will be decarbonised by installing air source heat pumps and improving both ventilation and energy consumption through the incorporation of a high performing façade and ‘smart’ controls.

Urban Greening
A landscape and planting strategy is proposed for the pocket park, the balconies and terraces, and the green roof. This will create an experience that enhances the building’s setting.

We will achieve a much higher Urban Greening Factor rating for the scheme, contributing to the greening of the City.

Flexible and Modern Office Spaces
We will be introducing 180,000 sqft of flexible offices, attracting a wide range of tenants by meeting the highest expectations of their employees.

Public Realm
Our proposals aim to activate the Public Realm and connect to the Culture Mile. This will include the retention of the current retail space on Holborn Circus and the introduction of a new one at the east of Charterhouse Street.

Externally, improvements to the site include re-landscaping the pocket park, using planting to provide protection and privacy to users.

Servicing (Transport Strategy)
Our proposals include the introduction of a new and effective servicing strategy by upgrading the existing basement spaces, and improved end of journey facilities to encourage active modes of transport to and from the site.
