Lochabers campaigners have argued that a plan for 325 houses on land behind an already-established housing scheme will face problems with drainage and smell.
Protesters have demanded a public meting and expressed concerns they have for the site at Cow Hill in Upper Achintore, Fort William, where planning for social housing is being considered by Highland Council.
The group will hand over 200 letters of objection to the development directly to planners in Inverness.
Rhona Grant, a resident of Upper Achintore, said: “People who live yards away from where this is going to happen have not been informed of the proposals.
“There was a public meeting when the council were building new offices that would have no impact on anyone, so I think it is high time we had a public meeting where we are all able to air our views about the housing.”
Social housing specialist, Link Group has lodged the application for the homes on the land at Cow Hill, which sits to the south of Fort William.
Janet Hickman, who believes the impact of the densely-packed housing will have long-term effects on the town said: “The area up onto Cow Hill is bog and peat land – something we want to preserve.
“At the moment, there is a continual problem with drainage, and the smell in the area can be terrible.
“Can you imagine what it will be like if even more people are living above the houses that already exist?
“We are a very happy community in Upper Achintore, there has been no thought given to the impact that building all this extra housing will bring. ”
However, Mark Linfield, who also lives in the area, said he in favour of the application.
He added”There is a big council waiting list, and we need the housing. So many people in Fort William are in properties where the rent is astronomically high.
“Hopefully, getting more houses onto the social housing and open market will change this for the better.”
Councillor Allan Henderson said: “This is what the planning process is about, hearing what people have to say and think about applications.
“As I sit on the committee, I am unable to say any more.”
