A date is yet to be set.

The decision to hold the summit came after an officer report triggered an hour-long committee debate on Wednesday about the efficacy of the document.

The 58-page strategy was drawn up to meet the council's statutory planning obligations, which include ensuring an extra 21,000 dwellings are built in the city by 2031.

During the meeting, Mayor Melva Hobson and councillors Helen Murray (Div10), Kathy Reimers (Div 8) and Barbara Townsend (Div 5) voiced opposition to parts of the strategy.

The mayor and Cr Townsend said they were concerned about the inflexibility of the strategy and wanted public consultation about medium-density zonings.

Cr Hobson called for the public summit in a bid to adjust the document and address the need for "density with dignity".

"I want to hear from the community, the designers, architects and not just the planners, the builders and the developers," Cr Hobson said.

"We have to think outside the box and I don't think anything in this document does that.

"I would like to see the summit based on density with dignity," Cr Hobson said.

Cr Murray said the strategy conflicted with the council's koala policy. She questioned the feasibility of building 90 per cent of new housing within 400m of public transport.

An officer told the meeting any changes to housing strategy would go to the council and the community for consideration before being included in the Redland Planning Scheme.

The housing strategy was drafted with input from developers, builders and accommodation providers.

Redlands Institute planning adviser Garry Hargrave welcomed the summit and said the housing strategy was flawed and based on incorrect projected population figures.

He said it was important the housing scheme was "not developed in isolation" and addressed social and environmental issues before being incorporated in the Redland Planning Scheme.

"A summit is a great idea because there are tough value decisions to be made, such as addressing the huge increase in housing density that is planned," Mr Hargrave said.

"It will also help to sort out the conflict between future growth and fauna preservation and also address the lack of provision of services for those aged between 18 and 38.

"There is also an over-reliance on the use of cars in Redlands and this strategy should address issues such as the poor intra-city transport infrastructure."
