Great Portland Estates (GPE) has pre-let 52,293 sq ft of workspace at London Bridge development The Delft to global data and AI software firm Quantexa.

The Delft, previously Minerva House, will be completed in spring 2027
Quantexa has agreed a 10-year lease to occupy the ground-floor East, first-floor East and fifth, sixth and seventh floors at The Delft, which is set to open in spring 2027.
The former Minerva House is being converted into 143,100 sq ft of grade-A HQ workspace on an island site close to London Bridge station and Borough Market.
GPE leasing director Marc Wilder said the deal follows “another strong quarter of leasing” for the firm, adding that it highlights London’s position as an “increasingly important central hub for AI-led business”.
Wilder said the building was now 38% pre-let, with “good interest in the remaining space”.
Ray O’Brien, chief operating officer at Quantexa, said: “London remains central to Quantexa’s growth and global ambitions. Our long-term commitment to The Delft underlines our confidence in the city and creates the right environment for our teams to collaborate, innovate and work side by side with customers and partners as we scale.”
CBRE and Savills advised GPE.
