Project Overview
With Mace now appointed as the Principal Contractor, the project enters the main new build phase.
The scope of works encompasses the following activities:
- Creation of basement box: A new reinforced concrete basement box will be formed extending to ground level
- Form new sub station: A new electrical sub station will be formed along Duke Street, this will be accessible from Street level
- Erection of New Core: A new reinforced concrete core will be erected, serving as a structural back bone to the new development above ground level. This will host the future access stairs, WC’s and lift lobbies.
- Erection of a New Steel frame: A steel frame, which is the largest reclaimed steel project in the UK will be erected. This aids the carbon reduction and sustainability credentials of the project whilst facilitating circular economy principes. This will allow the new façade and floor plates to be formed.
- Façade: Off site manufactured pre cast panels with windows will be installed to the building perimeter to seal all areas prior to internal works commencing. Where possible the existing Portland Stone for the project will be re-used and all of the glazing ground floor up will be recycled glass. All windows will be made from recycled aluminium which is the 1st time this is delivered in the UK within a Commercial Project. Zinc clad dormers will follow to complete the façade works. These will be pre fabricated off site to reduce carbon and impact to the local area.
- Fit out. Once the main structure and façade is complete, fit out work will commence to deliver CAT A office space, inc lift lobbies, WC’s, cycle and showers facilities and a new reception, which entrance will be from Duke Street.
- Commissioning: Once the majority of the building works and services is completed, all services will be tested to ensure the building is fully operational and meet all technical and sustainability credentials.

Minimise Disruption
We’re committed to managing the impact of the construction works so that disruption to the local area is kept to a minimum. A ‘Site Environmental Management Plan’ for the site has been approved by Westminster City Council and both John F Hunt and Mace will ensure compliance with this document.
This plan outlines how our construction works will take place as well as what mitigations will be put in place to minimise the impact on the local community during the works. This includes site operating hours, noise and vibration mitigation measures and monitors and how the traffic will be managed to and from site.
Throughout the construction process we will also ensure that the local community has access to the latest information on the key works taking place through regular updates, so that you can get in touch with any questions or to raise any issues relating to the construction works. We are also available to meet with you when requested to talk through the works and any queries or concerns.
Dedicated Construction Neighbourhood Liaison Manager
Mace Group has appointed a dedicated Construction Neighbour Liaison Manager to honour our commitment to minimise disruption for local residents, businesses and people who work and visit the area.
The Construction Neighbourhood Liaison Manager is working with all contractors on site, ensuring that neighbours are kept regularly updated and will respond promptly to any issues or questions that arise.
