Meadowhall's owners put their design for a £300 million extension on public display for the final time.
The plans for the glass-covered leisure hall went on show at the Millennium Gallery yesterday, with architects and developers on hand to chat to those who turned up.
People could browse a selection of CGI images and a 3D model, while also taking in a virtual tour.
Meadowhall's joint owner British Land has refined the design after public consultation and hopes to submit a planning application before Christmas.

Garry Wilding, of architect BDP, said the aim was to create a 'new face of Meadowhall'.
"We have added quite a lot of landscaping and greenery. We wanted a soft and welcoming environment.
"Greenery was the biggest change. We've also introduced a lot of photovoltaic panels."
The most striking aspect of the leisure hall is the latticed glass roof, which has echoes of the redesigned King's Cross station in London.
The 330,000 sq ft extension will include new restaurants, a state-of-the-art cinema, a gym and bowling alley. An outdoor terrace will give diners the option to eat outside, and could host live music.
Mr Wilding said: "We have had a lot of comments on the roof. We wanted a new face of Meadowhall. We are changing the unwelcoming front into a soft environment."
Including construction, the project will create about 2,000 jobs in the region.
Paul Case, of British Land, added: "We still have to go through the council but this is the intended final design.
"We have worked on sustainability. It was relatively early stages at the first consultation, so the design has just progressed. We have worked on transport.
"Generally the feedback was very positive around the design and people liked the environment we are trying to create."
Concern has repeatedly been raised about the conflict between Meadowhall and the city centre. But with Sheffield Retail Quarter moving forward, Mr Case there was no need to worry.
"It's crucial to Sheffield as a region that the two things sit together side by side and we are very supportive of the city centre scheme," he added.
