Ballalonna Farm, Dalby, Isle Of Man, IM5 3bw
The site is a converted Manx stone barn within a farmstead group in open countryside, featuring slate roofs and stone walls.

General Policy 2
Requires development to respect site/surroundings in siting/layout/scale/form/design (b), not adversely affect landscape character (c), protect habitats (d), maintain local amenity/character (g), provide highway/parking standards (h), and reduce energy use (n). Officer found proposal breaches (b)/(c)/(g) due to disproportionate gables doubling depth, harming barn character, reducing open space, and increasing farmstead coalescence/prominence in AHLV.
Housing Policy 15
Extensions to traditional countryside properties must respect proportion/form/appearance; normally only approved under 50% of existing external floorspace, exceptional circumstances required above. Proposal's 142.54sqm addition exceeds 50% of existing 231.32sqm (or original 165sqm), with no exceptional justification or verified calculations submitted, destroying sensitive balance of traditional barn.
Environment Policy 3
Criterion (a) avoids coalescence between built forms and protects built heritage of countryside. Increased bulk reduces open space between buildings in farmstead group, promoting visual coalescence, especially from Ballalonna Farm.
Environment Policy 4
Criterion (b) requires development to protect/enhance landscape quality. Proposal introduces unduly prominent built form into open AHLV countryside, harming farmstead setting despite no wider landscape harm.
Housing Policy 11
Barn conversions must provide satisfactory dwelling with modest/subordinate extensions not harming character; further extensions not usually permitted to avoid loss of original interest. Proposal's scale not modest, nearly doubling original floorspace, contrary to principle despite policy predating conversion.
