Lynsey Hyslop first sought permission to construct a new property on land in Stairhaven, however this was thrown out by DG Council.
A planning officer rejected the application in September last year on the grounds that the land is designated for agricultural use – and that the building would not comply with the local development plan.
However, a review of the decision was heard by the council’s local review body last week, with councillors upholding the original decision.
Lochar Councillor Ivor Hyslop said: “I don’t think there’s any agricultural justification information that has been supplied at any time with this.
“I think the officers, on this occasion, are justified to refuse this and I would support their decision.”
The applicant had argued that her parents are elderly and that she needs to be near them to help with the running of the farm.
She wrote: “My mother and father are getting older and still work full time on the farm along with myself when extra labour is required or if my parents are unwell.
“We need to be near to assist them with the day to day running of the farm and in ill health.”
However, there was no mention of this in the original application and councillors were advised that they could only review the original application, not new information, unless in exceptional circumstances.
They agreed unanimously to refuse planning permission.
