As regeneration advisor, Mace will review the current options for a key site called Spring Gardens, and investigate the wider Gloucestershire town opportunities.
Building on this, Mace will assist the council to develop a strategy on how best to deliver the project.
The Mace team working on the scheme have a track record of delivery for local authorities in the region including Taunton Deane Borough Council, Bristol City Council and Cornwall Council.
Included within their team is masterplanning architect, Lavigne Lonsdale, along with engineer, WSP.
Stuart Wilkinson, Director for Mace, said: “We’re obviously very proud to have been appointed by Tewkesbury Borough Council to assist with the delivery of such an important development opportunity for the town.
“This site provides the opportunity to deliver some transformative development in the centre of Tewkesbury, and we look forward to working closely with the Council to make the plans a reality.”
