Opposition is growing to plans for two housing developments on the edge of Paulton, which opponents fear could lead to the formation of a Midsomer Norton-Paulton conurbation.
One of the applications would see the last greenfield site between the two communities filled with 124 homes, with Edward Ware Homes wanting to build at Boxbury Hill.
An application has also been submitted at nearby the Paulton House business centre to convert offices into 58 one-bed apartments.
Both schemes will be discussed at a meeting of the parish council's planning committee on Monday, at 6.30pm.
Paulton councillor John Bull said both applications seemed to be unjustifiable, given that 600 homes had been earmarked for the village's Polestar site.
He said the applicants seemed to be taking advantage of the uncertainty over B&NES Council's core strategy blueprint.
"Not only will it throw more strain on the surrounding infrastructure, such as local roads and school places, but I believe it to be outside the housing development boundary, marking the limits of the village.
"Building here will be a further step to merging Paulton and Midsomer Norton."
He said that the Paulton House scheme seemed inappropriate and that keeping employment was more important for the village.
Residents living near Boxbury Hill are also concerned about the extra pressure on local facilities and roads.
Carole Fitzpatrick said: "It is the last field between Paulton and Midsomer Norton and without this boundary we will become one."
Midsomer Norton councillor Barry Macrae added: "This is appalling and another speculative and crass development. It makes a mockery of hopes for Midsomer Norton, Paulton and the Somer Valley."
Fellow councillor Paul Myer said that the Paulton House plans for a building once used by the DIY firm Focus threatened the future of the Somer Valley's newest enterprise park, with local employment space being removed in favour of more housing.
"It is often quoted that here in the Somer Valley we have the highest out-commute rate in the South.
"Surely the loss of this valuable space, which was re-christened by its current operators the Somer Valley Enterprise Park, will only exacerbate the situation?"
Developer Mr Ware said B&NES did not have a five-year supply of housing land.
He said: "We realise there will be some resistance to the scheme and we accept that people do not want new homes on their doorstep.
"We have one of the best architects in the country, Robert Adams, who designed the nearby Duchy estate on board to design these homes."
Property manager for the owner of Paulton House, Alan Powell, said that the building had been extensively marketed as office space and so far only 31 serviced offices had been occupied.
He said: "The intention is not necessarily for the whole building to be converted, but as much or as little as is called for depending on the market."
