Leeds Microsoft data centre approved: site layout and enabling works for engineers

First reported on The Construction Index
30 Second Briefing
Leeds City Council has approved a 500,000 sq ft hyperscale data centre campus at Skelton Grange for Microsoft, comprising three data halls plus auxiliary buildings and an outline-consented warehouse. Adjacent to the site, Harworth Group will deliver a further 160,000 sq ft of industrial and logistics space with EV charging on a separate plot. Harworth has already sold 27 acres to Microsoft for £51.2m and is progressing remediation and enabling works, with a second 21-acre phase to follow for £53.2m.
Technical Brief
- Microsoft’s land acquisition from Harworth in June 2024 covered 27 acres for £51.2m.
- Second phase (Plot 2) adds 21 acres, contracted to realise a further £53.2m on completion.
- Harworth, acting as regeneration specialist, is responsible for site remediation ahead of main construction mobilisation.
- Enabling works by Harworth likely include earthworks, ground improvement and service diversions to deliver “development-ready” plots.
- Split-phase land transfer structure allows Microsoft to stage capex and Harworth to sequence remediation risk.
- Co-located industrial/logistics and data infrastructure will drive heavy utility demand, influencing substation and grid-connection sizing.
- Similar brownfield data centre conversions in the UK often require extensive contamination management and foundation reuse assessments.
Our Take
Microsoft’s role here aligns with its parallel digital-transformation work with Codelco in Chile, suggesting the Skelton Grange site is likely to be integrated into a wider, high-spec cloud and AI footprint rather than a stand‑alone enterprise facility, with knock‑on implications for grid reinforcement and resilience standards.
Within our 803-item Infrastructure set, there are relatively few large, greenfield UK data centre approvals of this land-take, so Harworth Group’s ability to secure planning on 48 acres in Leeds will be closely watched by other brownfield landowners looking to reposition former industrial sites into digital infrastructure hubs.
