London, UK: The London Initiative for Safe AI (LISA), a non-profit working on the safety of artificial intelligence, has outgrown its home and chosen London's largest purpose-built life sciences and innovation campus as its next one. Reef + Partners and BlackRock Real Estate have announced that LISA is taking c. 7,620 m² across six floors of The Reflector, the second building at TRIBECA in King's Cross. The space will be fitted out over the coming months, with LISA expected to move in during 2027.
LISA's mission is to build the ecosystem needed to navigate transformative AI safely. It supports new talent entering AI safety, strengthens the organisations working in the field, and improves co-ordination between them, AI developers and policymakers. The new hub will be a place for researchers, developers and policymakers to work side by side and convene.
Krzysztof Bar, CEO at LISA, said: "The AI safety field in the UK is growing fast and LISA has already outgrown its current space." He added: "TRIBECA gives us room for the organisations and programmes working on AI safety today, and for the ones that do not exist yet."
TRIBECA spans c. 93,000 m² across four buildings and is being delivered in two phases. The first phase, The Apex, offers over 10,220 m² of laboratory space, with LBIC taking 3,620 m² and the Francis Crick Institute collaborating on 4,830 m². The final phase comprises The Reflector, The Assembly and The Connector.
Stewart Deering, CEO at Reef + Partners, said: "LISA is a fantastic addition to TRIBECA, enhancing the vibrancy and energy we aspire to create across the campus and strengthening collaboration between science, technology and AI."
Lewis Silkin LLP advised LISA on the real estate and construction aspects, including the pre-let of space in an active, multi-phase development, and continues to advise on the fit-out. Rachel Francis-Lang, Real Estate Partner at Lewis Silkin LLP, said: "This is a significant letting in one of the capital's most exciting commercial developments and reflects the growing demand from the technology sector for best-in-class space in the Knowledge Quarter."
The announcement does not address the market behind the deal, and it matters. UK laboratory vacancy reached a record 14.3% in Q2 2026, while the Golden Triangle of Oxford, Cambridge and London exceeded 25%. Delancey has switched most of a laboratory-led scheme on York Way in the same Knowledge Quarter to offices. Against that backdrop, a pre-let to an AI organisation, equal to roughly 8% of TRIBECA's floorspace by our calculation, suggests technology occupiers may help fill life sciences-led campuses. Rent, lease length and incentives were not disclosed, so how far that demand can stand in for lab take-up is still an open question.
