The officer assessed the principle of development in open countryside under Environment Policy 1, which protects countryside and allows extensions to existing rural dwellings if no adverse impacts.
Environment Policy 1
Protects countryside for its own sake; development should not have adverse impacts. The extension is within the existing garden, not resulting in loss of open countryside to the west, with no harm to countryside character.
Housing Policy 16
Extensions to non-traditional dwellings in countryside not permitted if increasing public visual impact. The single storey extension is subordinate, modest scale and height, sympathetic with matching materials, not increasing building impact as viewed publicly.
General Policy 2
Requires development to respect site/surroundings in siting, layout, scale, form, design, landscaping without adversely affecting landscape character or residential amenity. Proposal sits well under existing dwelling, no unacceptable visual or amenity impacts; subordinate design accords with Residential Design Guidance on side extensions (hipped roof, ridge below eaves, proportionate width).
Time limit
The development hereby approved shall be begun before the expiration of four years from the date of this decision notice. Reason: To comply with Article 26 of the Town and Country Planning (Development Procedure) Order 2019 and to avoid the accumulation of unimplemented planning approvals.

Key concern: potential for nesting birds if hedge removed
DEFA Biodiversity
Conditional No ObjectionIt is unclear from the documentation provided whether an area of hedge will need to be removed to facilitate the new extension.; If hedge is to be removed then this has potential for nesting birds.; All birds, their nests, eggs and young are protected by law (Wildlife Act 1990); Thorough checks for nesting birds must be undertaken prior to hedge and gorse removal; If any hedge is to be removed, we recommend that replacement features are created around the new extension as mitigation. Any new planting should be undertaken with Manx native species.
Conditions requested: Thorough checks for nesting birds must be undertaken prior to hedge and gorse removal; if nesting birds are present then removal must be delayed until nesting has finished and the young have fledged; Ideally any removal should take place outside of nesting season; If any hedge is to be removed, we recommend that replacement features are created around the new extension as mitigation. Any new planting should be undertaken with Manx native species
