Developer Graftongate have started construction of a £10 million development known as Gloucester 12.

Gloucester 12 sits adjacent to Gloucestershire Energy from Waste Facility in Hardwicke at Junction 12 of the M5 motorway.

The site already incorporates a 120,000 sq ft warehouse unit sold to International Plywood.

The four further units being developed will comprise; 17,516 sq ft, 26,465 sq ft, 38,227 sq ft and 41,288 sq ft.

Once complete, Graftongate said they will all boast air source heat pumps, a sustainable drainage system, higher than regulation insulation and electric vehicle charging points all helping to achieve a BREEAM "Very Good" rating.

Phil Silk, managing director of Graftongate, said: "This is the final phase of Gloucester 12 which will comprise four industrial/warehouse units totalling 123,500 sq ft.

"Having recently completed the infrastructure works and secured planning permission we have decided to speculatively build these units given the strength of the market and having identified a lack of supply particularly of the sizes being built."

Myles Wilcox-Smith, partner at M1 agency and Edward Jenkinson, senior surveyor at Bruton Knowles, are joint letting agents for the scheme.

Mr Wilcox-Smith added: "These units are scheduled to be completed in November and will be constructed to a high standard, above institutional standards, to include 12m to underside of haunch for the largest unit with a substantial level of power available to the site."
