Developers are hoping to regenerate a 1,200-acre site at Cardenden in Fife - and provide a blueprint for future sustainable communities.
The proposed scheme includes 5,000 new eco-homes, including terraced, semi-detached, detached and apartments, with at least 1,250 of the properties planned as "affordable" homes.
Banks Property Development, the firm behind the plan, say the new homes "would meet the highest sustainable energy standards".
There would also be an improved transport network, dedicated sports spaces for primary schools, and new public spaces and wildlife areas.
An initial outline of the scheme was produced last year, but today MSPs and senior policymakers saw more in-depth proposals at the launch of a report in Edinburgh.
Managing director of Banks Property Colin Anderson said that communities such as the one in Cardenden will help create a prosperous and low-carbon Scottish economy.
He said: "The principles of sustainability are increasingly at the centre of both building design and our everyday lives, and the proposals we are putting forward for Cardenden will set new standards in the delivery of zero carbon developments in Scotland.”
