Bromley Council has approved revised proposals for a first stage application to the Heritage Lottery Fund (HLF), which will help support the extension of Bromley Museum, London.
A previous bid for National Lottery support was unsuccessful, although the council has now drawn up a reworked submission. A decision is to be made by the HLF in summer 2012.
Bromley Council is looking to improve facilities at Bromley Museum with a reception area; a café; a landscape viewing platform; and additional exhibition spaces for local artefacts.
Peter Morgan, executive councillor for renewal and recreation, said: "While nothing is certain, we have carefully considered our resubmission to meet the requirements."
