Landsec starts work at Gunwharf Quays’ Marlborough Square

Landsec has broken ground at Malborough Square at Portsmouth’s Gunwharf Quays, marking the next step in the redevelopment of the outlet shopping destination.
This follows enhancements made earlier this year to The Avenues and is part of Landsec’s wider strategy to elevate the centre’s physical environment, boost operational performance, and enable stronger retail presentations. Work is set to complete in Spring 2026.
The programme includes refreshed building façades and shopfronts, enhanced public realm and landscaping, larger, modernised guest washrooms, additional public seating, and a new retail unit.
Tim Treadwell, head of retail portfolio at Landsec, said: “We continue to see strong demand from leading brands looking for premium environments to grow their outlet offerings. Gunwharf Quays is the perfect example of how Landsec is investing in its outlet portfolio to curate an environment that attracts even more guests, creates best-in-class experiences and supports the long-term success of brand partners.”
Landsec is looking to position Gunwharf Quays to better serve its affluent domestic and international customers, and has increasingly focused on aspirational retail and experience-led design. New lettings at the scheme include Russell & Bromley and Giggling Squid.
