The RTPI said it welcomes plans to expand growth points by 50,000 homes across England, while the Town and Country Planning Association added that the government's eco-town programme gives the chance to create zero carbon developments and lifetime homes.
But the Campaign to Protect Rural England said the government failed to communicate the environmental impacts of its proposals.
The RTPI and the National Housing Federation also welcomed the government's pledge to release public sites to help meet the target of three million homes by 2020. The federation added that surplus public sector land should be "auctioned off to the highest bidder".
Meanwhile hundreds of homes have been allocated for the first of eight public sector sites identified in the green paper.
English Partnerships announced this week that it has acquired the Connaught Barracks in Dover and aims to deliver 500 homes there. The 56ha site has 12.5ha that are suitable for housing.
The remaining area contains scheduled ancient monuments and open space. The agency will work with Dover District Council and English Heritage to create outline plans. It expects to appoint a developer by 2010.
