He said shoppers who could meet and socialise in the CBD were much more likely to remain in town, and shop, for longer periods.
"Creating a place where people will want to come and meet up with others would be a starting point in turning round the fortunes of Queen St."
This could involve making a section of the main street accessible only to pedestrians, along the lines of Cuba St in Wellington.
Mr Hart said he and Mr Taylor were not saying the district council should necessarily pick up the cost of creating a public meeting place as the district was "blessed" having several funding bodies.
"But perhaps the council could shepherd it through," he said.
In his written submission Mr Taylor said a town with no heart "is a dead one".
His vision was to see the creation of a mall, or plaza at the town's north end, landscaped and furnished in a similar way to Wellington's Cuba St mall.
The point of difference would be its "agricultural heritage and all-things-local model."
Enhancing the mall could be a market selling local produce, artisan crafts and featuring local entertainers along with displays such as cooking displays.
Mr Taylor believes that along with the withering of Queen St business there is also a disconnection between town and country.
This could be overcome by an expanded street market and by encouraging the return of such businesses as traditional "butchers, greengrocers and fruiterers."
Mr Taylor said an example of efforts to revitalise shopping centres was in Porirua where the city council has hired consultants at a cost of $30,000.
