Pages of documents showing where houses could be built in hundreds of streets and villages around Northampton, Daventry and Towcester have been published for the first time by the West Northamptonshire Joint Planning Unit (JPU).
The proposals are
so detailed they break the three towns into almost 900 separate areas, with numerous streets highlighted as possible targets for developers looking to build more than 48,000 houses between now and 2026.
The JPU has been keen to point out the publication of the documents does not mean any of the sites identified will certainly see development in the future.
But anti-expansion campaigners have accused the organisation of trying to sneak the plans under the radar to avoid negative responses from residents.
Roger Kingston, from campaign group The Northants Residents' Alliance, said: "This just looks to me like an open invitation for developers.
"And it just feels like the whole thing has been going on behind our backs.
"The last time they revealed plans like this, we all told them we didn't want them, but they're just carrying on as if nothing has happened."
The campaign group has also criticised the JPU for making the proposal documents difficult to find on its website.
Mr Kingston said: "Their website is pretty poor as it is, but to find these plans you have to know what you're looking for in the first place then keep on searching even further. It's doing anything but showing the big picture.
"But I would encourage everyone to go to the site and let the JPU know their views."
The Government has said it wants to see 62,125 new houses built in west Northamptonshire between 2001 and 2026.
So far, just under 14,000 of the houses have been built, leaving the JPU needing to find space for the remaining 48,000.
As part of its work, the JPU has looked at 885 separate sites spread out across Northampton, Daventry and Towcester.
Of those sites, more than 300 have been classed as "suitable for development" by the JPU while a further 281 have been classed as having 'potential'.
