Calderdale Council's vision for the major redevelopment of the Grade I-listed Piece Hall in Halifax, West Yorkshire, have gone on show as part of a public display at the site.

The local authority is planning to apply to the Heritage Lottery Fund next March in a bid to secure £6.7m towards the scheme, which will include the restoration of the building.

Other elements of the scheme include the development of the courtyard to create a new town square for Halifax and the opening of a new heritage centre exploring the site's history.

If the funding bid is successful, it is anticipated that work will be completed by 2015. Plans will remain on show next to the Piece Hall Visitor Centre and Art Gallery until 7 October.
