A proposal to redevelop part of Scotia Square in downtown Halifax has expanded from a low-rise office building into an office and residential complex that includes an 18-storey tower and commercial space on the ground floor.

Crombie Reit is behind The Westhill on Duke project located at the corner of Duke and Albemarle Streets.

Company representatives will be making a preliminary presentation of the new proposal at a meeting of the municipality's design review committee on Thursday.

The proposal includes a redesign of a breezeway that pedestrians along Albermarle Street use to get into Scotia Square.

The new look would include event space, seating areas and landscaped sections.

The developer's presentation says the change would allow the breezeway to be more than just a foot path.
