Farrat supply Structural Thermal Breaks to insulate connections across a 15,000t steelwork package, being erected at the new Edinburgh St James retail scheme

Edinburgh St James with egg shaped W Hotel

Edinburgh St James is one of the most significant construction and regeneration projects currently under way in the UK and the largest city centre development Edinburgh has seen for decades.

The £1bn project is replacing a 1960s shopping centre with 79,000m² of new retail space, alongside a new five-star W Hotel, an Aparthotel, 152 prime residential apartments, more than 30 restaurants and the city’s first Everyman Cinema.

Numerous column grid patterns requiring hundreds of tonnes of transfer structures, are helping to create the large retail-led mixed-use scheme, with a steelwork package totalling 15,000t of steel being fabricated by the appointed steelwork contractor BHC.

Following specification by the Architect, Farrat are set to supply over £90k of Farrat TBK Structural Thermal Breaks to thermally separate steel connections across buildings in the project.

As of March 2019, BHC had erected approximately one-third of the overall 15,000t of steel, a total that amounts to the company’s largest ever project. The steelwork package is due to complete in June 2020, with the project opening in phases, beginning with the retail and leisure element anticipated to complete in 2020, and the remainder of the development in late 2021 when the W Hotel and residential parts will be ready.


Farrat’s BBA certificated Structural Thermal Break materials provide building design professionals with a robust solution to minimise energy loss. Suitable to mitigate against planar, linear and point load thermal bridging, Farrat Structural Thermal Breaks can be used anywhere a penetration or transition exists in a building envelope to help achieve building performance standards. Performance characteristics include low thermal conductivity, high compressive strength and very limited creep under load.
