Housing is a major issue for the national park

A suggestion that planning permission would be needed for a house to become a holiday home could also be damaging, according to the officials' new report.

The park authority said it was consulting widely on its draft plan and it welcomed input from the council.

There has been a problem in the park over a lack of affordable housing.

One plan is to limit new homes to those who have been a resident there for at least three years, or work there.

Affordable housing

Under the draft proposals, the park authority would also have control over plans to turn existing residences into holiday homes.

However, Highland Council planners have said that the authority has overestimated by about double the amount of affordable housing needed.

The residency restriction, according to the report, has ignored the economic contribution made by those who commute to jobs elsewhere.

Officials pointed out that the park does not exist in socio-economic isolation from the rest of the Highlands.

Planners also warned that private sector investment in housing was likely to dry up.

Describing the authority's justification for its proposals as "unsound", the officials said the council should oppose plans which could undermine the prosperity of communities in the area.

The park authority said it was consulting widely on the its draft plan and local plan for the area.

A spokesperson said the organisation welcomed Highland Council's input and was awaiting a response from councillors on the planning and development committee, which will consider the officials' report.
