294 articlesWhen a designation boundary runs through part of a site
Split sites are assessed under two policy regimes at once. This covers establishing the boundary from the primary record, placing built form clear of it, and dealing with setting effects across the line.
Protected views and viewing corridors: testing a tall building
A protected view is defined geometry, so a tall building either intrudes on it or does not. Wireline studies from agreed assessment points answer that before any rendering is paid for.
Water neutrality: the constraint that stopped a housing market
Water neutrality requires a development to add nothing to total abstraction in its area. The duty arises under the Habitats Regulations, so it cannot be negotiated away.
Scheduled monuments: consent, setting and works that need it
Works to a scheduled monument need consent from the Secretary of State, not the council, and doing them without it is an offence. Development in the setting is a planning question instead.
Bathing and shellfish waters as a planning constraint
Bathing water and shellfish water designations bite on drainage rather than land use. How to find them, what the Environment Agency and your undertaker will say, and the conditions to expect.
Local Nature Reserves and development nearby
Local Nature Reserves are declared by councils under the 1949 Act and sit in the local tier of policy protection. The indirect effects that defeat applications and the evidence that answers them.
Protected vistas and strategic views in London
A London protected vista is a defined corridor with a threshold plane, not a general presumption against height. How the components work and what evidence a borough expects.
Article 4 directions that remove householder rights
A direction moves the decision from the permitted development order to the council. No application fee is payable, but the design evidence expected goes up.
Village design statements and their planning weight
The same design statement counts for a great deal inside a made neighbourhood plan and very little if the parish council simply printed it. Adoption route decides weight.
Strategic view corridors and the assessment method
A view corridor is geometry you either breach or clear. The wider setting and background areas are judgement, and that is where most refusals on view grounds come from.
Drinking water safeguard zones and land use
Safeguard zones are catchment designations made where raw water quality is deteriorating. They change the drainage, slurry and contamination evidence a rural application needs.
Peat soils and the policy against disturbance
Drained peat oxidises and keeps releasing carbon long after the works finish. The first questions on a peat site are how deep it goes and what the scheme would do to the water table.
Overhead lines, clearances and undergrounding a plot
Conductor clearance is a safety requirement, not a policy test, so it cannot be argued away. Work out the usable envelope from the operator's corridor first, then design the dwelling into it.
High pressure gas mains and building proximity distances
A high pressure gas main brings three separate constraints: the registered easement, the operator's building proximity distance and the HSE consultation zone. Find all three before the layout is drawn.
Safeguarded waste sites and the capacity argument
Objections to development on a safeguarded waste site turn on capacity, not amenity. How the test works, what evidence counts, and what to do when the site is next door rather than underneath.
Priority habitat inventory checks and what they trigger
The priority habitat inventory maps habitats of principal importance under section 41 of the NERC Act 2006. How to check it, ground truth it, and plan around the survey seasons.
Smoke control areas, wood burners and flue permissions
Smoke control areas under the Clean Air Act 1993 restrict what you can burn and in what. How to check your address, meet the appliance and fuel rules, and work out whether the flue needs permission.
Safeguarded transport routes and what you can still build
A safeguarded transport route gives the scheme promoter a consultation veto over anything that would prejudice future works. Here is how the direction operates, what still gets permission, and when a blight notice is available.
Metropolitan Open Land and how it differs
Metropolitan Open Land applies Green Belt style tests to strategic open space inside London's built-up area, with designation criteria that are distinctly urban.
Natural cavities, gypsum and chalk mine instability
Unlike coalfield areas, chalk mines and dissolution features have no statutory referral body. Nobody tells you the risk is there, so the desk study has to find it.
Historic landfill and the 250 metre gas buffer
The 250m landfill screening distance is a prompt to build a conceptual site model, not a boundary. The programme risk is the monitoring, which can run for months.
Radon affected areas and the protective measures
Radon is a Building Regulations matter rather than a planning one. The probability band for your plot decides whether you need a sealed membrane, or a membrane plus a sump.
Building beside a canal: the navigation authority view
The navigation authority owns the water, usually the towpath and often the bank. None of that is settled by your planning permission, and its consents run on their own timetable.
Development beside the railway and what the operator asks
Planning permission does not give you the right to work near a railway. Fencing, drainage, piling and oversail are settled by the infrastructure owner, and that process runs on its own timetable.
