Planning & Constraints
Planning restrictions, protected areas, and development limitations
Area of Archaeological Potential
Historic core with likely buried remains
An Area of Archaeological Potential is a zone where buried archaeological remains are thought likely to survive. In Northern Ireland these zones cover the historic cores of towns and villages. The Department for Communities Historic Environment Division maps them. England, Wales and Scotland flag likely buried archaeology through their own local plan designations instead.
Area of Significant Archaeological Interest
Protected historic landscape around monuments
An Area of Significant Archaeological Interest is a distinctive historic landscape holding a group of related sites and monuments. The designation exists only in Northern Ireland. A district council designates it in its local development plan, advised by the Department for Communities Historic Environment Division. It carries development plan policy rather than a separate consent regime.
Article 4 Direction
Restricted permitted development rights
An Article 4 Direction removes specific permitted development rights across a defined area. Changes that would normally need no planning permission then require a full application. The local planning authority makes the direction and decides which rights it withdraws. Every UK nation has its own permitted development rules, so what a direction removes varies.
Brownfield Land
Housing on a previously developed site
Brownfield land is land with a previous built use, such as a former factory, warehouse or demolished building. The term is planning shorthand for previously developed land. Local planning authorities identify it through the planning system, and every UK nation does so under its own policy.
Building Preservation Notice
Temporary listing while a decision is made
A Building Preservation Notice is emergency, temporary listing, served by a local planning authority. It protects a building of likely special interest that is at immediate risk, for up to six months. In England the Secretary of State then decides the listing, advised by Historic England. Historic Environment Scotland decides in Scotland, the Department for Communities in Northern Ireland; Wales has no such notice.
Built-up Area
Physically developed urban land
A built-up area is land covered by continuous built form: buildings, roads and hard surfaces rather than open countryside. Ordnance Survey and the Office for National Statistics map it from the physical built footprint, not any planning boundary. It is a statistical description, not a planning designation. The dataset covers Great Britain; Northern Ireland is mapped separately and not included.
Certificate of Immunity
Confirmed not listed for five years
A Certificate of Immunity from listing confirms that a building will not be listed for five years. In England the relevant Secretary of State issues it, advised by Historic England. It also blocks a Building Preservation Notice, the council's temporary listing power, for the same term. Wales, Scotland and Northern Ireland each run an equivalent certificate.
Common Land
Private ground with historic rights of use
Common land is privately owned land over which other people, the commoners, hold legal rights. Those rights typically cover grazing animals or collecting wood, and often date back centuries. The county or unitary council registers it, as commons registration authority. The system runs in England and Wales only; Scotland and Northern Ireland have no commons register.
Conservation Area
Extra planning controls to protect local character
A conservation area is a place of special architectural or historic interest, protected for its character and appearance. The local planning authority designates it and draws the boundary. Extra planning controls apply inside that boundary. All four UK nations use conservation areas, and each runs its own consent rules.
Green Belt
Protected open land around towns and cities
Green Belt is a planning designation that keeps land around towns and cities permanently open. Its purpose is to check urban sprawl and stop neighbouring towns merging. Local planning authorities draw the boundaries in their local plans. Each UK nation sets its own policy; Wales has the framework but very little designated green belt.
Heritage at Risk
Historic England's register of places in poor repair
Heritage at Risk is Historic England's register of designated historic places at risk from neglect, decay or unsympathetic change. It covers listed buildings, scheduled monuments, conservation areas, registered parks and gardens, battlefields and wreck sites. The register records condition; the underlying designation, such as listing, controls what can be altered. Heritage at Risk is an England register; the other UK nations record buildings at risk through their own schemes.
Listed Building
Statutory protection for special historic interest
A listed building is a structure of special architectural or historic interest, protected by law. The decision to list rests with government in each nation, except in Scotland, where Historic Environment Scotland lists directly. Grading is devolved: England and Wales use Grade I, II* and II, with Grade I the highest. Scotland uses categories A, B and C; Northern Ireland uses grades A, B+, B1 and B2.
Listed Building Curtilage
Protection reaching outbuildings, walls and gates
Listed building curtilage is the ground and structures around a listed building that share its legal protection. It can cover an outbuilding, garden wall, coach house, gate or barn not named on the list. Historic England maintains the list in England. Wales, Scotland and Northern Ireland each run their own listing regime with equivalent curtilage rules.
Planning Applications
Council register of proposed and decided works
A planning application is a request to the local planning authority for permission to build or alter. The authority publishes every application, its documents and its decision on a public planning register. This report reads that register for this address and for the surrounding neighbourhood. All four UK nations run their own planning system, and every authority keeps a register.
Protected Wreck Site
Historic shipwreck protection offshore
A Protected Wreck Site is an area of seabed designated around a historically or archaeologically important shipwreck. The designation covers the wreck and the seabed around it, not any land or buildings. Historic England advises on designation and licenses access in England. Scotland has no Protected Wreck Sites; its historic wrecks are Historic Marine Protected Areas designated by Scottish Ministers.
Registered Battlefield
Ground where a nationally important conflict was fought
A Registered Battlefield is ground where a nationally important battle was fought and where the site remains recognisable today. Registration protects the historic landscape and any archaeology buried below it. Historic England keeps the Register of Historic Battlefields for England. Scotland and Wales hold their own inventories; Northern Ireland has no equivalent.
Registered Historic Landscape
Mapped Welsh countryside of outstanding or special interest
A Registered Historic Landscape is an area of countryside, parkland, coastline or river valley of outstanding or special historic interest. Cadw compiles the Register of Landscapes of Historic Interest in Wales. The register is non-statutory, so it is a planning consideration rather than a consent regime. Wales alone keeps such a register; the other UK nations have no counterpart.
Registered Park or Garden
Designed historic landscape of special interest
A Registered Park or Garden is a designed landscape of special historic interest. It can be a country house park, a formal garden, a public park, an arboretum or a historic cemetery. Historic England enters these sites on the National Heritage List for England and grades them I, II* or II. Each UK nation keeps its own register or inventory of designed landscapes.
Scheduled Monument
Nationally important archaeological protection
A Scheduled Monument is a site or structure of national archaeological importance held on a legal schedule. It can be a ruin, an earthwork or remains buried under a garden or paddock. Historic England advises on the English schedule. The other three nations each schedule under their own regime.
Tree Preservation Order (TPO)
Council consent needed before cutting or felling
A Tree Preservation Order protects specified trees from being cut down, topped, lopped, uprooted or wilfully damaged. The local planning authority makes the order, after judging that the trees matter to the look of the area. An order can cover a single tree, a group, a defined area or a whole woodland. All four UK nations use tree preservation orders, each under its own rules.
World Heritage Site
Globally important place inscribed by UNESCO
A World Heritage Site is a place inscribed by UNESCO for its outstanding universal value. Some are cultural, such as historic cities and monuments; others are natural landscapes. Sites are inscribed by UNESCO's World Heritage Committee on the nomination of the UK government. All four UK nations have them.
World Heritage Site Buffer Zone
Setting protected around an internationally important landmark
A World Heritage Site Buffer Zone is land around a World Heritage Site, protecting its views and setting. UNESCO's World Heritage Committee agrees the buffer zone; the local planning authority applies it through the ordinary planning system. It is a planning consideration, not a separate consent regime. Buffer zones exist in England, Wales and Scotland; Northern Ireland's only World Heritage Site has none.
