Sirius Minerals


Sirius Minerals were opening a new mine site in North Yorkshire and needed high-quality office and welfare accommodation for their teams. As one of the biggest construction projects in the North of England, the mine was set to create up to 2,500 jobs and £2.5bn of exports.


Two mixed used buildings were designed to create a high quality environment for the teams working on site. 43 bays were installed, along with a six-bay medical facility, welfare facilities including shower blocks, changing rooms and kitchen. A large office space and meeting rooms included movable partitions to give flexibility to house 100+ desks. 

To ensure the safety of employees, the buildings were equipped with a full Cat 6 Data fire alarm system, alongside a modular security gate house and security check area to welcome contractors and people visiting the site.


  • The company’s commitment to lowering their environmental impact meant that eco-friendly and sustainable solutions were essential
  • High safety standards required an experienced team to manage and deliver the project
  • The building needed to blend with the local landscape and reduce impact for nearby residents.


The buildings were painted in dark green to fit in with the landscape of the North Yorkshire Moors, in line with the client’s mine design strategy. Our experience and ISO 14001 certification meant we were able to design a building with minimal environmental impact, including specially designed metal shutters to create a blacked-out building at
night to reduce disturbance for local residents.

Our solution for Sirius was designed to enable additional floors to be added later as staff numbers increase, offering the option for more office and welfare space as the project gathers momentum.


“High safety standards and low environmental impact are the two major criteria that we have to fulfil for all our on-site construction, and Premier’s building design has allowed us to achieve that. Sirius is also committed to working with local businesses and developing a strong local supply chain, so we are delighted that working with Premier has allowed us to continue to fulfil that commitment.”
