LONDON, UK – FEBRUARY 10, 2025 – Yondr Group, a leading global developer, owner and operator of hyperscale data centers, has celebrated the start on site of the third building at the company’s London campus in Slough.

Once completed, the 40MW data center will bring the total capacity of the London campus to just over 100MW, making it one of the largest in the UK. The groundbreaking brings the site of a derelict paint factory back into commercial use. The event follows completion of the first 30MW building at the London campus in July last year. An additional 30MW data center is currently in the construction phase on site.

Yondr’s third building on the London campus has been designed to BREEAM ‘Very Good’ standards, to deliver both reliable data capacity and sustainability. The new facility will be energy efficient in line with the company’s sustainability strategy and 2030 target for Scope 1 and 2 carbon neutrality. Solar panels will be installed on the building’s roof and the facility will boast industry-leading power utilisation efficiency (PUE).

Plans for the building were developed in close collaboration with Slough Borough Council and the Canal & River Trust, with the goal of realising a building that actively enhances biodiversity and improves the canal side, with a focus on aesthetics and active transport access for local residents.

A green wall facing out towards the canal is one of the ways in which aesthetics and sustainability have been integrated into the project, as part of a strategy of blending the building with its surroundings. The green wall has been designed on an independent structure to overcome the technical requirements of the data center and it will provide both visual and acoustic shielding, in addition to contributing to biodiversity.

Yondr’s commitment to sustainability will extend beyond the border of the site for the new data center, with the planting of trees and shrubs which have been specially selected to be sympathetic to local plant species and wildlife.  A new walking and cycle route will contribute to the health and fitness of the local community and help to reduce vehicular traffic by creating a convenient cut-through.

In a further step to create a positive impact in the local area, Yondr conducted a community needs assessment which highlighted challenges children face in accessing outdoor learning opportunities. To help bridge this gap, Yondr has provided funding for six classes from local schools for a day of hands-on learning at the Iver Environment Centre – allowing the children to immerse themselves in biodiversity, conservation, and the importance of protecting the environment. 

Peter Hill, VP of Design & Construction EMEA at Yondr commented: “The plans for this third building on our London campus show a clear evolution of our data center design and delivery capabilities. It demonstrates just how far we have come in embracing sustainability to deliver our carbon neutrality goals and bring forward exemplar data center developments.

“Breaking ground on this project is a milestone not just for this building, but also for our London campus and our increasingly strong presence in Europe. I’d like to thank everyone who has helped progress this project through the design and planning stage, as well as those who have joined us to celebrate today, and I look forward to a smooth construction process and handover next year.”

The facility is expected to be completed in mid-2026.
