Development work can now start on a key regeneration project expected to create up to 3,000 jobs after reclamation works were completed.
Up to 150,000 sq ft of employment space can now be built at the Advanced Manufacturing Hub (AMH) in Aston.
The hub is one of six economic zones being promoted by Birmingham City Council to fast-track economic development and is a joint venture with the Homes and Communities Agency (HCA).
Work at the 9.3-acre site included the removal of foundations, redundant services, hard standing and old car parks.
It has been made possible with a £1 million investment through the Greater Birmingham and Solihull Local Enterprise Partnership (GBSLEP) City Deal, a £22 million investment fund to accelerate priority economic and housing projects across Birmingham.
Property consultancy Savills is currently marketing the site and secured its first occupier last year after HydraForce purchased a 6.7-acre plot to develop a 120,000 sq ft manufacturing base.
Over a 15-year period, the AMH will deliver 49 acres of employment land and generate up to 3,000 jobs.
Chris Webster, board director for GBSLEP, responsible for optimising assets and Enterprise Zone champion, said: "Vital space for employment and business to expand and locate to the Greater Birmingham and Solihull area is being realised due to the AMH.
"It is providing investment via the City Deal Public Assets Accelerator, an innovative partnership developed to create a rolling asset-based vehicle to unlock the potential of underused public land for housing and employment.
"Additional investment, secured as part of our £357 million Growth Deal, will go a long way to expanding the economy in the region and increasing the prospects for even more jobs and the continued opportunity to deliver growth."
Coun Tahir Ali, Birmingham City Council's Cabinet Member for development,, added: "This exciting development captures the importance of the advanced manufacturing sector to Birmingham and the West Midlands and will provide opportunities for the growing automotive supply chain, as well as other advanced manufacturing activity, demand for which is forecast to accelerate, given the successful performance of this industry across the region."
