Aviemore Community Council has reaffirmed its support for a 1,500 house new village nearby.
The community watchdog said the An Camas Mor project is needed to deliver new housing in the area.
Developers behind An Camas Mor recently applied to have their planning permission for the development extended.
The idea of a new village on Rothiemurchus Estate, across the River Spey from Aviemore, was backed in principle in 2014 by the Cairngorms National Park Authority (CNPA).
But planning permission is due to expire soon because of a lack of progress on site.
Aviemore Community Council previously gave the project their blessing – and has reaffirmed their support, calling on the CNPA to “not hold the community back”.
Chairman John Grierson said: “The community council supports the creation of a new sister community to Aviemore at An Camas Mor.
“The community council would like to reiterate again the need for further housing for people with local jobs in the area and we believe that An Camas Mor helps alleviate that issue.
“The only other alternative to provide the further housing required is to develop the land between the northern boundary of Aviemore and the dump.
“However, this is a strategy the community council does not support as it will lead to further extension of the ribbon development that Aviemore has become.
“There is insufficient public infrastructure in Aviemore to deal with that expansion. An Camas Mor has the infrastructure built in to its design.”
They also said they see the creation of a footbridge crossing the Spey and linking the two villages as “desirable” but said it should not be built until construction at An Camas Mor makes it viable.
A spokesman for An Camas Mor said: “The development will create a sustainable new community with a unique combination of affordable housing, small business premises and community facilities in a woodland setting.”
He added: “We look forward to working with the Cairngorms National Park Authority over the weeks and months ahead to enable us to make this exciting project a reality and realise the long term benefits for the people and businesses of the area.”
