9571 articlesLocal plan viability evidence and how it sets policy
Once a plan has tested its policy requirements cumulatively, a complying application is assumed to be viable. Reading the evidence base tells you both where the requirements came from and what you are arguing against.
Planning permission for indoor karting or axe throwing
Karting falls outside Class E because the class excludes motorised vehicles, which makes it sui generis. Axe throwing can sit within Class E(d), and that one difference decides whether you need an application.
Checking local plan policy numbers against the adopted plan
Policy citations are the first thing an officer checks and the easiest thing to get wrong. How to find the adopted plan, handle saved policies and verify every number before submission.
Transient overshadowing of a children's play area
Play areas are assessed on sun on ground rather than on window criteria. The equinox benchmark, the difference between transient and aggregated outputs, and the planting scenario most studies leave out.
Surface water flood risk where the flood zone says low
The Flood Map for Planning maps fluvial and tidal risk only, so a Zone 1 site can still sit on a surface water flow route. The separate datasets to check and the measures councils accept.
Noise contours around an airport and new housing
Aircraft noise comes from above, so fences, orientation and planting achieve almost nothing. The whole case rests on the contour band, the glazing and ventilation strategy, and the closed-window overheating model.
Class ZA: demolishing and rebuilding a block of flats
Class ZA pins the new building to the old footprint and allows 7 metres of extra height capped at 18 metres. Design, natural light and the method of demolition are all prior approval matters.
Planning permission for an aesthetics clinic above a shop
Moving into a former office or salon above a shop is not development, because both sit in Class E. Moving into a former flat is, and the loss of residential accommodation is the hardest part of the case.
Drafted biodiversity text against the statutory metric
A biodiversity section built on sentences cannot discharge a condition measured in habitat units. The parts of the submission a draft handles well, and the survey work that has to come first.
Outlook and the distance to a blank wall
There is no national separation distance in England. Local guidance descends from a 21 metre window-to-window convention and its halved figure to a blank wall, and both are starting points rather than standards.
Presenting residual flood risk after mitigation
Residual risk is what remains once the mitigation is built and working, plus what happens when it is not. Officers read this section first, and adjectives in place of numbers invite a holding objection.
Safeguarded wharves and rail aggregate depots
A safeguarded wharf or rail depot restricts what can be permitted nearby, not only on the site itself. The policy question is whether new development would prejudice the operator's ability to keep working.
Fences, gates and walls: the 1 metre limit beside a highway
A footway is part of the highway, so most front boundaries are limited to 1 metre. Height is measured from the higher ground level, and trellis counts towards it.
Planning permission for a dry cleaners using solvents on site
A drop-off dry cleaners is a Class E service use. Install the machines and you add a permit, an extraction case, a plant noise case and, where flats sit above, a solvent vapour case.
Using a drafted statement for a section 73 application
Section 73 puts only the conditions in issue, so the statement should be short and precise. The parts a generated draft gets right, and the decision notice and history you have to supply yourself.
Daylight to a neighbour's permitted development extension
Windows in a neighbour's permitted development extension are assessed like any other, yet their low existing values make proportional tests easy to breach. Room status and baseline history decide the weight.
Build over agreements where a public sewer crosses a site
A public sewer under the garden needs the undertaker's build over or build near agreement, which is separate from planning permission and from building control. Here is how to check the line and what to do about it.
Protected vistas and the height a scheme can reach
Protected vistas control height through viewing corridors, wider settings and background areas. Your ceiling comes from projecting the threshold plane across your own footprint, then deducting the roof zone.
Class AA upward extension: measuring the roof correctly
One additional storey may add 3.5 metres to the highest part of your existing roof, two may add 7 metres, and attached houses face a separate limit measured from the tallest adjoining building.
Planning permission for a film studio or sound stage
A studio campus with stages, workshops, offices and a backlot rarely fits any use class, which changes the policy argument, the acoustic evidence and the conditions you should offer up front.
The drainage hierarchy and justifying a sewer connection
A drainage strategy that starts at the sewer and works backwards gets rejected. What evidence rules out infiltration, and which consents sit outside planning.
Checking national designation data against the council layer
Datasets are representations of a designating instrument, not the thing itself. Which document decides, who holds it, and how to evidence a boundary error.
Counting the 28 days of temporary use under Part 4 Class B
Twenty four trading days looks comfortable until build and strip are added. How the allowance is counted, where the market sub-limit bites, and what falls outside it.
Permission for a seasonal maize maze or farm attraction
Part 4 Class B covers a maze or a pumpkin field. It does not cover the hardcore track, the levelled parking or the toilet block, which is where most operations go wrong.
