A huge £300 million regeneration scheme which could create more than 1,000 jobs has been unveiled for a Birmingham suburb.

The proposal by Sainsbury's builds on a previous plan to breathe new life into Selly Oak's former Battery Works area, and would be one of the biggest schemes of its kind in the city. Now the supermarket giant is set to seek permission for a 98-bed hotel, and 380 apartments in two complexes at Selly Oak's "Triangle" site - and expand on its plans for the old Battery Works site.

Overall the project would create a 54-acre centre with a waterfront residential and shopping area as its heart.

A spokeswoman said previous outline permission had been granted for a 65,000 sq ft Sainsbury's store at the ex-Battery Works site. That would be double the size of its existing Selly Oak outlet and be among the company's largest UK stores.

The previous outline permission also proposed a new canal basin connected to the Birmingham and Worcester canal with canal-side shopping and residential areas.

The company is planning to apply for new permission to create more homes and more shops on the Battery Works sites.

A spokeswoman said overall the scheme would lead to new restaurant and leisure facilities providing "a vibrant focus for the development, and nearby over 330,000 sq ft of office and technology buildings will form a new commercial quarter, providing flexible commercial space for a variety of end users."

She said the company would be seeking partners in the project, which would cost around £300 million, and create more than1,000 jobs when complete. An application for the Triangle site and a fresh application for the old Battery Works site are due to be submitted to Birmingham City Council early next year.

The proposals would also include a petrol station.

Sainsbury's would also provide the first stage of the long-awaited Selly Oak New Road, and in conjunction with the City Council is already creating 85 new allotments for the local community.

Over the next month, a consultation programme will be held in Selly Oak, involving exhibitions for the general public together with briefings to local councillors and organisations as part of a preapplication exercise to generate feedback from the community.

Anthony Shapland, Sainsbury's project director, said: "Although we have worked closely with the community for some years, we continue to place great importance on the views of local people and believe the final proposals will benefit from their input.

"This is currently the largest Sainsbury's development in the UK, and amongst other benefits is set to provide over one thousand new job opportunities for Selly Oak."

The exhibitions will be held at the Sainsbury's store and at other locations in the local area from today.
