Project Description

Overbury has recently refurbished PwC’s Embankment Place HQ in London, surpassing all BREEAM achievements to date by achieving a landmark 96.31% Outstanding score; the highest BREEAM rating recorded worldwide.

Working closely with PwC, TP Bennett, Turner & Townsend and Chapman BDSP, Overbury ensured that the sustainability knowledge and expertise of the entire supply chain was identified and utilised from the start.

The ambitious project revitalised the dated, lightless and inefficient office space while 2,000 staff remained in occupation.

Responsible business



Throughout the duration of the project, Overbury undertook a range of activities to engage with the local community. This included regular workshops with residents and businesses to ensure the project plan worked for everyone and regular neighbourhood watch meetings with representatives from local authorities, emergency services, businesses and local residents to help keep people informed.


The health and safety of site workers was a key priority for the project team, prompting a number of actions to promote best practice. This included a comprehensive no smoking campaign, a free fitness boot camp for Overbury workers and sub-contractors, a healthy eating menu in the canteen, free onsite training for sub-contractors and a contractor/employee of the month health and safety reward scheme with green cards for positive interventions.


PwC employees were invited on regular site visits whilst the works were taking place, allowing them to keep up to date with progress and see first hand what is needed to undertake a project of such a scale.


In order to promote the construction industry and associated opportunities for women, the project team held a ‘Females in Construction’ event on site.


Overbury also made a number of donations, including food to the homeless and carpets to a local school.



In order to achieve the landmark BREEAM Outstanding score of 96.31%, a host of sustainable features were included in the design. This includes a tri-generation combined cooling, heat and power system, fuelled by recycled waste vegetable oil that is collected and refined locally to a new efficiency standard by Uptown Oil and South Bank University. Chiller beams have been fitted to replace the previous air conditioning system and low-power lift braking has been installed along with eco-friendly carpet tiles. A large amount of open plan space maximises natural light, roof gardens and green walls enhance the building’s ecology and low flush toilets have been introduced to reduce water usage.


During the construction process, 96% of waste was diverted from landfill and a large amount of steel work was reused.


To further reduce the carbon emissions of the project, the Overbury team utilised a consolidated centre to minimised part deliveries, took part in Earth Hour seeing all lights switched off, and offered and promoted a cheap cycling scheme.


Such extensive actions have led to the building having an Environmental Performance Certificate of A.



During the construction process of the project, 95% of materials sourced responsibility.


Due to the extensive occupational cost savings associated with the project, the refurbishment is expected to pay for itself in less than four years.
