294 articlesSettlement boundaries and building just outside one
Cross a settlement boundary by a metre and the policy changes completely. The exceptions that work, the out of date plan argument, and the five documents a countryside site needs.
World Heritage Sites: Outstanding Universal Value in practice
Schemes in a World Heritage Site are judged against the attributes that carry Outstanding Universal Value, not against townscape character. Here is how to read the statement and design to it.
Veteran trees: identifying them before the layout is fixed
Ancient and veteran trees are treated as irreplaceable habitat, with a buffer based on fifteen times stem diameter or five metres beyond the canopy. Here is how to identify them, why they cannot be replaced and how to hold a layout around them.
Nutrient neutrality catchments and what a scheme must show
In affected catchments a council cannot grant permission until an appropriate assessment rules out harm to a protected site. Here is how the nutrient budget works, which mitigation routes exist and how they must be secured.
Coal referral areas and the coal mining risk assessment
A site in a coalfield high risk area attracts a statutory consultee and a report requirement. Doing the desk study early is the difference between a condition and a refusal.
Archaeological Priority Areas and the tier system explained
London boroughs map archaeological potential in tiers. The tier your site sits in decides whether a desk study will satisfy the adviser or whether trenching has to happen before determination.
Sites of Special Scientific Interest: consent inside the boundary
Owning land inside an SSSI brings a separate consent regime under the Wildlife and Countryside Act 1981. Routine farming operations on the notified list need Natural England's written consent.
Contaminated land registers and what a search shows
A clear contaminated land register is not evidence that a site is clean. The register records formal action under Part 2A, and almost every real case is handled through planning instead.
Railway boundaries: Network Rail asset protection in planning
Network Rail is only a statutory consultee in narrow circumstances, yet its asset protection requirements can hold a site up for months. Deal with them before the application, not after the decision.
Safeguarded wharves and building beside a waterway
Wharf safeguarding survives long periods of disuse, and the burden of showing a wharf is no longer viable sits with the applicant. Waterside sites carry their own consents and liabilities.
National Landscape setting: developing outside the boundary
The boundary on the policies map does not end the landscape argument. Sites outside a National Landscape are assessed on setting, and the statutory duty was strengthened in 2023.
Inset or washed over: how Green Belt villages differ
Whether your village is inset or washed over decides which policies apply to your property. One is judged on ordinary development management grounds, the other on Green Belt exceptions.
Conservation area consent and demolition control
Demolition in a conservation area is controlled through planning permission, not a separate consent. What counts as relevant demolition, what is excluded and the notices that run alongside.
Tree Preservation Orders: area orders against individual trees
A Tree Preservation Order can name one tree or cover everything standing in an area on a given date. The four classifications, how to check yours and what consent involves.
Town and village greens: the registration risk to a site
Registration as a town or village green happens outside the planning system and is close to irreversible. The section 15 test, the trigger events that block it and how to deposit a landowner statement.
Public rights of way across a development site
A footpath across the site is a separate consent regime with its own timetable. Start the order before the permission, not after the contractor arrives.
Local Wildlife Sites and the weight they carry
Local Wildlife Sites have no statutory protection and still stop schemes. Here is where their weight comes from and how to scope the evidence properly.
SSSI Impact Risk Zones and Natural England consultation
Impact Risk Zones sit well outside SSSI boundaries and catch far more small sites than owners expect. Here is how to read them and what to submit.
Nutrient neutrality catchments and what they require
In an affected catchment a council cannot grant permission for overnight accommodation until nutrient neutrality is demonstrated. The duty comes from habitats law, not planning policy.
Critical Drainage Areas and what they add to an application
Sites in Flood Zone 1 usually escape a flood risk assessment. Inside a Critical Drainage Area they do not, and the evidence is about surface water rather than rivers.
Minerals Safeguarding Areas and prior extraction
Minerals Safeguarding Areas cover large parts of England and catch ordinary housing sites. Here is what the mineral planning authority will ask for and how to answer it.
Aerodrome safeguarding zones and what they restrict
Safeguarding is a consultation regime rather than a prohibition. It catches tall buildings, water features, solar arrays, landfill and cranes, sometimes many kilometres from a runway.
Coastal Change Management Areas and what they allow
A CCMA is a local plan designation for land expected to be physically changed by the sea. It does not ban development outright, and the permissions granted inside one look different.
Scheduled monument consent and how it differs
Scheduled monument consent is not listed building consent and it is not granted by your council. It comes from the Secretary of State under the 1979 Act, and unauthorised works are a criminal offence.
