Seven Capital's mission to transform a run-down part of the Jewellery Quarter has taken the next important step after detailed plans were lodged with the city council.

The company, which acquired the Kettleworks building earlier this year, is seeking permission to convert the site into 313 apartments ranging from studios to three bedrooms and forms part of the wider St George's Urban Village project.

It was one of a trio of property deals completed by Seven Capital within the space of a few weeks in the spring and one of several recent investments by the property development company into Birmingham.

Kettleworks is bounded by Pope Street, Camden Street and Icknield Street and was acquired along with a 1.8-acre plot of land on which Seven Capital intends to deliver a total of more than 600 apartments.

This latest application is for the part demolition, part conversion and part new-build of the site to deliver a gym, recycling area, 234 parking spaces and landscaping in addition to the flats.

A design statement accompanying the application said: "The building has been empty for many years. Many developers have tried to resurrect the site under various planning permissions.

"The building has been used by squatters and many needles and waste have been discovered in the buildings.

"Any responsible proposal to generate brown field or derelict urban development land should provide social and economic opportunity.

"In the case of developing this site, there will be an immediate economic uplift, created by inserting new quality urban fabric into the area, the inhabitants of which would be able to reinvigorate and add to the vibrant nature of the Jewellery Quarter.

"The proposed development will make a valuable and vital contribution towards the delivery of hew high quality homes in the city centre and bring back into active use a vacated, previously developed site."
