Castle hands over three Wynyard developments
The Hebburn-based contractor has completed a 48,000 sq ft Sainsburys, a 45,000 sq ft terrace of seven trade units, and a 1,850 sq ft Starbucks drive-thru at the Tees Valley retail park.
Developed and owned by Northumberland Estates, the Wynyard Trade and Retail Park is located within Wynyard Business Park and will be occupied by a range of businesses, including Howdens, Screwfix and Doves.
The project has seen Castle teams involved in initial enabling works, statutory services, earthworks, groundworks, frame and envelope through to partial MEP services and external services including associated roads and car parks.
Castle was appointed on the project in May last year, with Northumberland Estates obtaining consent for the project in February 2024.
Architect Whittam Cox and planner Lichfields advised on the scheme.
The units are all aiming for BREEAM Very Good standard.
Craig Muldoon, divisional director of build, Castle, said: “It is very satisfying to complete, on behalf of our valued client, Northumberland Estates, a sectional handover on this major project and, in particular, the delivery of a Sainsbury’s superstore, which will create a huge number of jobs and act as a real pull to drive footfall right across the Retail Park.”
Peter Dalby, Northumberland Estates development manager, said: “From the outset, our vision has been to create a high-quality destination that strengthens the local economy, attracts nationally recognised occupiers, and generates significant employment opportunities.
“The completion of these key phases marks a major milestone in realising that vision and firmly establishes Wynyard as a premier retail and trade location in the Tees Valley.”
