London's elite office boom leaves mid-tier spaces struggling amid AI land grab

Demand for top-tier office space in London is surging, with rents climbing by 12% in the past year. British Land’s prime locations now have little available space, while AI firms and tech giants rush to secure premium premises. The shift is reshaping key business districts across the capital. The Knowledge Quarter, stretching from Fitzrovia to King’s Cross, has become a magnet for AI companies. OpenAI, the creator of ChatGPT, and DeepMind are both expanding into the area. Meanwhile, Project Prometheus, backed by Jeff Bezos, is setting up its UK base nearby. One Triton Square, a key building in the district, is already attracting high-profile tenants.

Elsewhere in London, other tech hubs like Silicon Roundabout and Broadgate remain in demand. Derwent’s Network building in Fitzrovia is fully pre-let to Databricks, a US AI analytics firm. This trend reflects a broader pattern: in the first quarter of 2023, 92% of pre-let offices were classified as ‘Grade A’—the highest quality available.

Yet not all office providers are thriving. Workspace, which specialises in smart but non-elite spaces, has seen its shares drop by 16%. US activist investor Boaz Weinstein is now pushing for the company to be wound down. Meanwhile, Great Portland Estates reports that AI tenants occupy around 12% of its office portfolio, highlighting the sector’s growing influence. The shift toward premium office space shows no signs of slowing. With AI firms driving demand, top locations are filling up quickly, leaving mid-tier providers under pressure. Rents continue to rise as competition for elite workspaces intensifies.
