Property developer and investor Barberry Group was behind the scheme at Kingswood Lakeside Business Park, Cannock,.
The company is relocating its regional operations to the new HQ, bringing much-needed investment and dozens of new jobs to the area.
Bob Clarke, operations director at Allpack, said: “The past 12 months has seen the ecommerce sector grow to new records and this facility will further enable us to develop and grow our business whilst continuing to service our customer needs and requirements.
The 3.5-acre site was acquired by Barberry from Staffordshire County Council. Barberry secured detailed planning permission and appointed construction contractor Benniman. The ground treatment works required to enhance this prime employment location were part-funded to the tune of £2 million by the Greater Birmingham and Solihull Local Enterprise Partnership via its Local Growth Fund.
