Located on Tornado Way in Darlington, this 24-acre site was strategically chosen for its access to key transport routes. The A66 and A1(M) connect the development to major distribution networks across the North East and beyond. The location allows for efficient last-mile deliveries and quick access to major urban centres like Middlesbrough, Stockton, and Durham. The area is also part of a wider plan to attract innovative industries, supporting Darlington’s ambition to become a leading logistics and industrial hub.
Design Philosophy: Sustainability as Core, Not Add-On
Net Zero Carbon in Construction and Operation
The foundation of Greenbox Darlington’s design is its commitment to achieving net zero carbon in both construction and ongoing operations. Every stage of the build — from material sourcing to energy systems — has been assessed for environmental impact. During construction, low-carbon fuel alternatives were used to reduce emissions, and recycled materials such as steel and aggregates were prioritised. The project achieved significant reductions in embodied carbon and diverted all construction waste away from landfill.
The completed buildings are designed to operate efficiently, with photovoltaic-ready roofs that support solar panels, smart energy systems, and low-energy lighting. The site is also equipped with rainwater harvesting, high-efficiency insulation, and intelligent heating and cooling systems that adapt to operational needs while minimising waste.
High Environmental Standards
Greenbox Darlington was designed to meet exceptional environmental standards. It targets BREEAM “Excellent” certification and an EPC A rating, placing it among the highest-performing logistics developments in the country. These standards ensure that the buildings consume less energy, have lower operating costs, and maintain a smaller carbon footprint over time. Such credentials make Greenbox Darlington an attractive choice for tenants committed to meeting their environmental, social, and governance (ESG) targets.
Smart Material Use and Efficient Structure
The use of recycled and low-carbon materials was a major consideration in Greenbox’s construction. Recycled steel, low-carbon concrete, and sustainable insulation materials were incorporated to reduce embodied carbon. Large skylights maximise natural lighting, decreasing energy consumption during daylight hours. The floors were built with heavy-duty FM2 slabs that can handle substantial industrial loads, ensuring durability and flexibility for a wide range of uses. Landscaping was also designed to promote biodiversity, creating a more natural and appealing environment.
Key Specifications and Layout
Greenbox Darlington consists of three large industrial units ranging in size from approximately 84,000 to 215,000 square feet, collectively offering over 400,000 square feet of high-specification logistics space. Each unit features high clear internal heights of up to 15 metres, generous yard depths of up to 50 metres, and a combination of dock-level and level-access loading doors for operational flexibility.
The buildings include spacious offices fitted to Cat A standard, providing tenants with modern working environments ready for customisation. Parking areas include electric vehicle charging points, and service yards are designed to accommodate heavy goods vehicle manoeuvring with ease. All buildings are secured with 24-hour gated access and equipped with advanced fire safety and lighting systems.
Market Appeal and Letting Strategy
A Speculative Build with Confidence
Greenbox Darlington was built speculatively, meaning construction began before tenants were secured. This approach demonstrates the developers’ confidence in the site’s location, quality, and long-term demand for sustainable logistics space. The development’s green credentials are a major selling point, attracting occupiers who want facilities aligned with their sustainability commitments.
Early Success and Tenant Interest
The development achieved practical completion in early 2025, and by mid-year had secured its first major letting. Leading trade merchant Wolseley signed a lease for more than 100,000 square feet within the complex, demonstrating the growing appetite for net zero-ready logistics space. This early success not only validates the developers’ vision but also highlights a wider market trend: businesses are increasingly prioritising environmentally responsible facilities.
Connectivity and Workforce Access
One of Greenbox Darlington’s major strengths is its connectivity. The location offers immediate access to the A66 and A1(M), ensuring efficient distribution to major UK cities and ports. Within an hour’s drive, occupiers can reach Teesport, Newcastle Airport, and several urban centres, while the surrounding region provides a large, skilled workforce. This combination of transport links and labour availability makes it an ideal location for national logistics and manufacturing operations.
Economic, Environmental, and Social Impact
Environmental Impact
The developers estimate that more than 11,000 tonnes of carbon dioxide emissions were avoided during the construction phase compared to conventional methods, with additional offsets achieved through verified carbon credit schemes. The project demonstrates how industrial development can deliver tangible carbon savings without compromising scale or efficiency. In operation, the buildings are expected to maintain low energy demand through advanced systems, renewable integration, and continuous monitoring.
