Proposals to convert a barn and construct three new homes in Kislingbury have been refused by South Northamptonshire Council.
People from 14 nearby homes objected to the proposals, along with Kislingbury Parish Council and Northants County Council Highways department.
Highways officers said the access via School Lane was too narrow, has no footpaths, has poor visibility for pedestrians and noted the close proximity of the village primary school.
Councillor Roger Clarke, SNC’s portfolio holder for planning and environment said: “This was a proposal for a small number of homes within a built up area.
“It is not often that we get such a clear argument against development of this kind, but the increase of traffic along a narrow lane used by lots of children and parents could not be overlooked.”
A failure to demonstrate the proposals would not compromise the wellbeing of nearby protected trees was also cited on the reasons for refusal.
