Skanska HQ: Decoration to meet the WELL Building Standard

The Project: 

Decoration and firestopping services, as part of the development and construction of the Skanska 45,000 sq ft (4,180sqm) London head office site.  

Located at 51 Moorgate, the site includes three floors of Skanska personnel, as well as retail and commercial tenants into the rest of the space.  Designers hoped to achieve a modern, sustainable, and healthy workplace where people and businesses can thrive.

Our specialist team helped Skanska and architects John Robertson Associates achieve their vision through a superior decorating finish that responds to the project’s WELL certification aims. 

Client: Skanska

Sector: Office

Region: London

Services: Decoration, Firestopping

The Challenge:

Skanska invited us to design a decorating solution to meet the building’s ambitious WELL Building Standard.  Specifically, to ensure materials reduce human exposure to hazardous building material ingredients through the restriction or elimination of compounds or products known to be toxic and the promotion of safer replacements.

The Results:

Our innovative approach helped us to deliver full decorating and firestopping services to support Skanska’s WELL certification aims.  

Working with a range of products, including Intumescent paint, CP2 paint and backless fabric wallpaper, the Sentinel Contracting team transformed the 45,000sqft (4,180sqm) commercial building including:

  • new build seventh-storey rooftop level
  • reconfigured reception area with public café 
  • ground floor cycle storage and changing facilities
  • eight floors of office space 
  • ground-floor retail space

Mark Stewart, Director, Sentinel Contracting plc, says: “This ambitious project set out to meet the WELL Building Standard, support occupiers aspiring to WELL certification, and to create a modern workspace in the heart of The City that promotes health, wellbeing and productivity.  We’re proud to have contributed with materials that mitigate the impact of decoration on the environment, and to have achieved such a stunning end- result.”



The Sentinel team are pleased to have recently completed decorating works at the £150m K1 Knightsbridge development in London’s most prestigious postcode.  

Our firestopping skills will be put to work on this great project at 20 Ropemaker Street which consists of 419,093 sq ft of office space and 11,785 sq ft of ground level retail space.

We put safety, quality, innovation and sustainability first
