Major development status without any new floorspace

Major development with no new floorspace is common, and it catches applicants out because people assume major means big buildings. The definition in article 2 of the Town and Country Planning (Development Management Procedure) (England) Order 2015 has five limbs, and only one of them mentions floorspace. The others reach mineral working, waste development, dwelling numbers, and any development on a site of one hectare or more.

So a 1.2 hectare car park is major development. A small waste transfer station is major development. Regrading a field is major development if the site is large enough. Each brings a 13 week determination period, press notice publicity and the full consultee list, whether or not a single square metre of floorspace is created.

The five limbs of the definition

Read them as alternatives. Meeting any one makes the application major.

The site area limb is the one that does the unexpected work, because it has no qualifying words about buildings, use or scale of activity. It asks a single question: how big is the application site.

Note also what the dwellings limb does on an outline application where the number is not stated. A 0.6 hectare site promoted for an unspecified number of homes is major even if the eventual scheme is five houses.

Site area as the operative test

Site area means the area of the application site, which is the land within the red line on the location plan. That includes everything you have drawn in, including the parts you are leaving alone.

Items that commonly push a site over a hectare:

• the full extent of a yard or hardstanding where only part is being altered
• access roads and verges included for highway works
• landscaping, attenuation basins and habitat areas added to satisfy other policies
• land included to demonstrate control for drainage outfall or visibility splays
• existing parking retained but shown inside the red line for completeness

That last point is worth dwelling on. Including land you are not changing can convert a minor application into a major one, with months added to the timetable. Where the land does not need to be in the application, put it in blue as land in the applicant's ownership instead of in red.

Equally, do not shrink the red line to dodge the threshold where the works require that land. An application that excludes the access it depends on invites a validation query, and an officer who thinks the red line has been drawn tactically will say so in the report.

Waste and minerals are major whatever their size

These two limbs have no size qualification at all, which surprises small operators.

Waste development means development for the purposes of, or a change of use to, waste management. A skip hire yard, a small transfer station, a soil screening operation, a household waste recycling point, an anaerobic digestion plant: all waste development, all major, however modest the site. In most areas the determining authority is also different, because waste and minerals are county matters outside unitary areas.

The practical consequences arrive immediately. A 13 week target rather than eight. Publicity by press notice as well as site notice. Consultation with the environment regulator, the lead local flood authority and the highway authority. And a validation list that expects the full suite of technical documents, including a Waste Management Strategy setting out how material will be handled on site.

Minerals works the same way. A small sand extraction, or the deposit of mineral working material, is major from the first tonne.

Engineering operations, car parks and open land

Beyond waste and minerals, the site area limb picks up a long list of schemes with no building at all.

Engineering operations, which is a category under section 55 of the Town and Country Planning Act 1990 covering works such as regrading, excavation, embankments, ponds and hardstanding formation. A 1.5 hectare reprofiling of farmland for drainage is major development.

Open land uses, where the use changes without construction. Open storage of vehicles, plant or containers. A caravan or camping site. A motorsport or outdoor leisure use. Sports pitches with no buildings. Solar arrays, which are usually several hectares and therefore always major.

Car parks and servicing yards, where the land take is substantial and the built element is a barrier and a payment machine.

Illustrative example. A haulage operator applies to change the use of 1.3 hectares of former agricultural land to lorry parking, with a surfaced yard, drainage and perimeter fencing. No floorspace. The application is major on the site area limb, triggering the longer determination period, newspaper publicity, and consultation with the highway authority and the lead local flood authority. Because it is major, the biodiversity gain condition applies in the usual way for development of that scale, and the baseline has to be assessed on the pre-development habitat. That case is illustrative, and the exact requirements depend on the authority's validation list.

What changes once the application is major

The shift is procedural rather than substantive, and it is worth listing because each item has a programme cost.

1. The determination period becomes 13 weeks, or 16 weeks for development subject to environmental impact assessment, instead of eight.
2. Publicity requires a notice in a local newspaper in addition to a site notice or neighbour notification.
3. A Design and Access Statement is required for major development, so a Design and Access Statement has to be prepared even for a scheme with no buildings, addressing layout, access and landscape.
4. Statutory and non-statutory consultees are engaged more widely, and their response times drive the programme.
5. The application is more likely to go to committee under the authority's scheme of delegation.
6. Fee bands differ, and for development of land without buildings the fee is calculated on site area, so the same measurement that creates major status also drives the cost.
7. Planning obligations and levy liability follow scheme characteristics rather than status, as set out in our note on obligations and the levy at different scheme sizes.

On biodiversity, the gain condition and the 10 per cent requirement apply according to the statutory regime rather than to the major label alone, so check the position for your development type. Where it applies, the metric and gain plan must be prepared by a competent person under the Environment Act 2021 framework, and a Biodiversity Net Gain Assessment draft is a starting point for that professional rather than a substitute for their work.

Measuring the red line properly

Measure from the survey, not from an online mapping tool, and state the figure in hectares to two decimal places on the forms and in the statement.

Three conventions to apply consistently. Include the full width of any highway land within the application site, because part-width inclusion is a frequent source of discrepancy. Measure to the centre line of a boundary feature only if that reflects the ownership. And keep the area on the forms, the location plan and the technical reports identical, since a discrepancy between 0.98 and 1.02 hectares is the difference between minor and major.

In London there is a separate layer again, because referral to the Mayor runs on its own thresholds that are not the same as the major development definition, as our note on Greater London Authority referable thresholds explains.

Checking status before choosing the application type

Do this before anything else, because it determines the programme, the fee and the document list.

Measure the site area from the survey. Check whether the proposal is waste or minerals development. Check whether the proposal creates 1,000m² of floorspace or ten dwellings. Then ask whether any land inside the red line can properly be moved outside it.

If the answer puts you marginally over a hectare and the land is needed, accept major status and programme for it. Budget 13 weeks plus consultee time, allow for a committee date, and commission the documents accordingly. Discovering the status after submission, when the validation officer reclassifies the application, costs more than planning for it.
