Architecture + Design Scotland (A+DS) slammed the scheme, which proposed restoring the listed house, converting it into 15 dwellings, the adjoining stable block into 10 dwellings, and creating 54 new builds.
Although A+DS agreed in principle with the restoration of the house and stables, and with the management of the surrounding woodland, it stated that the new properties were a major stumbling block in the plans.
The comments are a hammer blow for developer Manor Kingdom Group, and Roy Mitchell Design, as the majority of the funding for the project was to come out of the 54 new builds.
In its report, the A+DS said: 'The location of new housing to enable the project has not been justified. We believe it is in the wrong place, and will have a detrimental effect on Dunmore Park House and its setting.'
The report continued, stating that the proposals 'relied on instinct', and that 'further analysis is required derived from historic understanding of context to inform the placement and design of new housing.'
It is unclear whether Roy Mitchell Design will continue with the project, but what is certain is that it will not be granted planning until significant changes are made.
