Snowdonia National Park
The park authority decides applications here. Great weight to conserving the landscape; major development restricted.
Landscape, scenic beauty and wildlife carry great weight, and major development is only allowed in exceptional circumstances.
World heritage site: World Heritage Site
Nationally designated heritage. Its significance and setting carry great weight.
Registered parks and gardens, battlefields, world heritage sites and protected wrecks are designated heritage assets: harm needs clear and convincing justification.
Harlech conservation area
Demolition needs planning permission and permitted development is restricted.
The council must give weight to preserving or enhancing the area's character and appearance. Not every council has published its boundaries as open data.
Special area of conservation 150 m away: Coedydd Derw a Safleoedd Ystlumod Meirion / Meirionnydd Oakwoods and Bat Sites
Work nearby can need a habitats assessment.
Harm to a protected site is only accepted where there is no alternative and an overriding public interest.
Scheduled monument 138 m away: Castell Harlech
Its setting is a consideration for work nearby.
Nationally important archaeology protected by the Secretary of State. Work that affects the monument or its setting is rarely permitted.
SSSI 150 m away: Coed Llechwedd
Natural England may need consulting, depending on what is proposed.
Sites of special scientific interest are the best wildlife and geological sites in the country. Development likely to harm one is rarely permitted.
