Stepnell has marked the completion and handover of several units to expand Hazeley Enterprise Park near Twyford, Hampshire, with tenants moved in and starting to operate on site.
Stepnell is transforming the site of a former chicken farm and feed mill into a thriving industrial and commercial hub for Hazeley Group. The completed scheme will provide an additional 18 light industrial units and 12 grade A office units, bolstering Hazeley Enterprise Park’s existing portfolio of 18 fully occupied units to address a shortage of high-quality business space in the region.
The first completed light industrial units include standalone unit 29 and adjacent units 30 and 31, the latter two having been let to one tenant with a breakout door installed. Units 34, 35 and 36, which adjoin one another, are also now fully occupied by one tenant, featuring an office mezzanine as well as additional HVAC, mechanical and electrical infrastructure to account for the tenant’s additional requirements to operate plug-in warehouse equipment.
Unit 20, a grade A office premises comprising of four office suites, has also been completed.
Rob Speirs, director at Stepnell, said: “Hazeley Enterprise Park demonstrates our extensive multidisciplinary expertise that is enabling us to deliver one of the most transformative industrial and commercial projects in South Hampshire, led by our growing South team based in our Southampton office.”
Prior to construction, Stepnell coordinated an extensive ground remediation programme to remove buried contamination on the former site of a chicken farm and feed mill, including asbestos, hydrocarbons and a redundant fuel tank. Stepnell cleaned and reused approximately 40,000 cubic metres of material on site, reshaping a 12-acre field into a natural swale and biozone that manages surface water and supports biodiversity.
As a result of Stepnell’s extensive remediation works, the project was shortlisted for best land and soil investigation project at the Environment Monitoring and Measurement Achievement Awards 2026.
Stepnell’s Group businesses have also been heavily involved in delivering the units. Renewables business Step Energy has fitted solar panels across the units, with electric vehicle charging provided as standard. The Hazeley Hub, due to open in spring 2027 featuring a cafe, meeting and event spaces, includes bespoke joinery created by Lawford Bespoke Joinery.
Rob added: “The extensive remediation programme was completed long before the first unit went up. Our early involvement is a large contributing factor that has enabled these units to hand over on time with tenants moving straight in.
“Sustainability and social value run through every stage of the project, from Step Energy’s implementation of low-carbon energy management schemes to supporting local jobs and apprenticeships, with primary groundworkers based within five miles of the site and work experience opportunities on site through our subcontractor partners.
“As we continue to engage with our local supply chain to deliver the remaining units, including the first office unit which is nearing completion, we’re excited to help businesses establish a new home on this landmark enterprise scheme for Twyford and the surrounding area.”
Nikki Bream, group managing director at Hazeley Group, said: “We are very proud of the quality of the units that have been delivered by Stepnell, and of the fact that the whole of Phase One is either already occupied or under offer, including units that will not be handed over until the end of the year. We look forward to continuing to work with Stepnell on Phase Two, which we expect to commence before the new year.”
