NTT London LON3: 24MW High-Density Dagenham AI Campus

Status: Active / Under Heavy Structural Construction (Tracking June 2026)   |   Location: Yew Tree Ave, Dagenham RM10 7FZ, United Kingdom

Project Overview

The NTT London LON3 Data Center Campus represents one of the most significant next-generation digital infrastructure developments underway in the United Kingdom, strategically located in the Dagenham area of East London to expand NTT’s extensive portfolio of premium colocation and hyperscale facilities beyond the increasingly constrained availability zones of central and West London. Purpose-built from the ground up to accommodate the rapidly escalating demands of artificial intelligence training, machine learning inference, deep learning applications, high-performance computing, and hyperscale cloud platforms, LON3 is being engineered with a highly optimized, high-density architecture capable of supporting substantial power loads, advanced cooling systems, and future-ready computing environments. As of mid-2026, construction is progressing rapidly through major structural framing activities, core building envelope installation, and the integration of primary electrical, fiber, and utility infrastructure, positioning the campus as a critical new digital hub for the London metropolitan region. The development offers a strategic advantage by avoiding the severe power availability and grid capacity constraints affecting traditional data center clusters in areas such as Slough and other West London corridors, where increasing demand has created significant deployment challenges. Designed to meet rigorous international standards for physical security, operational resilience, and sustainability, the campus incorporates advanced environmental controls, energy-efficient technologies, and compliance measures aligned with stringent UK green building regulations and corporate ESG objectives. Once operational, LON3 will provide global hyperscalers, cloud service providers, financial institutions, and enterprise customers with highly secure, scalable, and low-latency connectivity to central London’s digital ecosystem, enabling seamless interconnection, enhanced business continuity, and long-term support for the continued growth of data-intensive technologies across the UK and Europe.
