A SHELL, the escarpment or a wave - they are the choices for residents wanting a say on the design of the contentious $57 million Shellharbour City Hub project.
Architects appointed to the project presented the three concept designs last week.
Architects from DesignInc and Lacoste + Stevenson have produced designs that feature in a community engagement program.
The proposal includes administration offices, council chambers, a library, a museum and a civic auditorium, set for completion in December 2016.
The hub - which council staff recently reported was affordable - is to be funded by developer contributions, asset sales and loans.
Each design is within the overall budget of $57 million.
Their names reflect elements of their shape - shell, escarpment and wave, with the civic square at the highest point of the site in each design.
The community buildings are incorporated into the main square and street frontage. They each support 100 on-site parking spaces, and 67 in an expansion of the Gadu Lane car park, opposite the site.
DesignInc project director Richard Does said the schemes shared some common features.
"They've got the same square metreage per space, the same sort of auditorium space, the council chambers, the admin building; all are very similar in floor area," he said.
Mr Does said a "mix and match" of certain elements of the designs was possible, depending on feedback.
"One of the interesting things about the wave scheme is that as the roof dips down, we can create a rooftop viewing platform."
Hub critic Cr Kellie Marsh previously called for a hub referendum, backed by Barrack Point's Harry Gooden from the project's community reference group, in response to community concerns.
Mayor Marianne Saliba rejected the suggestion.
"If we had a referendum every time we had to make a decision based on money, we would never get any work done," she said.
"There are a small group of people who continue to perpetuate misinformation."

Residents can also have their say on the project via an independent online survey.
Manuel Cruz, a long-time Shellharbour City resident now living in Shell Cove, has set up a ratepayers' survey which he said is entirely independent of the council.
"Results will be certified by a JP and will be provided to the Lake Times for publication, and to the mayor," he said.
"The council doesn't want to hold a referendum.
"The council doesn't appear to be interested in doing anything to get any genuine feedback."
