Runway East has signed a 15-year lease with Samsung at 200 Aldersgate in the City of London, securing 35,000+ sqft in the 400,000 sqft building near St Paul’s.

Natasha Guerra, Runway East’s CEO, called it a significant step for the flexible workspace sector.

Billy Hodges and Holly Bailey shared CBRE‘s London Flex Market Update report for Q1 2026 that shows tenant demand is up sharply, with flex requirements rising 40%, and 43% of transactions coming from TMT (tech, media, and telecom) clients, mostly AI-driven companies looking for smaller, agile spaces near major transport hubs.

Prime flex office rates are up roughly 10% across core submarkets, with operators like Runway East and Industrious expanding into high-quality West End locations, while landlords like Yoo Capital are increasingly partnering with flex operators rather than leasing to traditional tenants. CBRE expects 2026 to be a record year for flex transactions, driven by a tight development pipeline, fast-growing AI companies, and a maturing flex market that now supports longer-term occupier commitments.
