The supermarket giant planned to build a new foodstore, with petrol station, car parking and landscaping, an indoor market and outdoor market area in Great Homer Street.

Sainsbury's has committed to taking a 110,000 sq ft store in the Project Jennifer scheme. As well as the superstore, Project Jennifer includes a 965 space car park, petrol filling station, 80,000 sq ft of non-food retail stores, a market hall and 300 relocated outdoor market stalls, 481 new homes, facilities for the Primary Care Trust, a new library, leisure facilities, 80,000 sq ft of light industrial space and improved public realm.

It is expected that land assembly will begin in spring 2010.

St Modwen was selected by Liverpool City Council as preferred developer in 2004 and a development agreement was signed in 2005. Outline planning permission for the scheme was granted in 2007.
