Educational accommodation and the Gateway One dwelling count

If you are checking whether student accommodation gateway one applies to your scheme, counting bedrooms is the wrong exercise. Article 9A of the Town and Country Planning (Development Management Procedure) (England) Order 2015 defines a relevant building as one that contains two or more dwellings or educational accommodation, and that has seven or more storeys or is 18 metres or more in height. The dwelling limb carries a count. The educational accommodation limb, on its natural reading, does not.

So a 19 metre purpose-built student block is caught whether it holds 40 beds or 400, and a nine-storey hotel of the same size is not caught at all.

The two limbs of the relevant building test

Read the definition as two gates that both have to open.

The first gate is what the building contains: two or more dwellings, or educational accommodation. The second is scale: seven or more storeys, or a height of 18 metres or more. Fail either and Article 9A does not bite.

The scale test has its own measuring conventions, and they catch people out more often than the use test. Height is taken from ground level to the floor surface of the top storey, excluding any rooftop storey given over to plant or machinery. Storeys below ground level are not counted in the storey total. A building with two basement levels, a ground floor and six upper floors is a seven-storey building for ordinary description and sits below the storey trigger for Article 9A purposes, which is exactly the kind of result that needs stating on the application form rather than left for the validation officer to work out.

Where a scheme sits within a metre or a storey of the line, document the measurement. Our note on fire evidence for a building just below the threshold covers what to submit when you are arguing you fall outside the regime, and the short answer is a dimensioned section with the measurement convention stated on it.

Why purpose-built student housing is caught

The educational accommodation limb exists precisely because student housing sits awkwardly in the dwelling definition. A cluster flat bedroom with an en suite and a shared kitchen is not obviously a dwelling, and a studio with its own kitchenette arguably is. Rather than leave that argument to each authority, the drafting brings residential accommodation provided to students by a school or college within the test directly.

That means the planning use class of the building does not resolve the question either. Student blocks are variously consented as sui generis, as Class C2 or, less often, as Class C3, and none of those labels changes whether Article 9A applies. The question is what the building contains in substance.

The practical upshot for developers of purpose-built student accommodation is simple. At 18 metres or seven storeys you are in Gateway One, a fire statement is a validation requirement, and the Building Safety Regulator within the Health and Safety Executive becomes a statutory consultee on your application.

Cluster flats and how rooms are counted

Because the educational accommodation limb does not carry a numerical threshold, the counting exercise that matters for conventional residential schemes largely falls away here. On a block of flats you need two or more dwellings. On a student block you need educational accommodation, full stop.

Counting still matters for the design, though, and for the fire strategy the statement has to summarise. Cluster flats are usually treated as single fire compartments containing several bedrooms, so the number of bedrooms per cluster, the arrangement of the protected corridor and the travel distances within the flat all drive the strategy. A 10-bed cluster with a single internal corridor is a materially different proposition from a four-bed cluster, and the statement should describe which arrangement the scheme uses.

Mixed buildings complicate matters further. A block with commercial floorspace at ground level, student clusters above and a handful of market flats on the top two floors will satisfy both limbs of the use test, and the statement has to describe evacuation strategies that may differ between the tenures.

Hotels and care settings compared

This is the comparison most often got wrong, because the planning regime and the building control regime draw their lines in different places.

The care home row is the awkward one. A scheme can sit outside Gateway One at planning stage and then be a higher-risk building at Gateway Two, which means the fire engineering has to be developed to the same standard but without the discipline of an early regulator view. On those schemes the sensible move is to commission the strategy as if Gateway One applied, because the alternative is discovering a fundamental problem after permission is granted.

Verify the current definitions in both the Order and the Higher-Risk Buildings (Descriptions and Supplementary Provisions) Regulations 2023 before relying on the table, since both have been amended.

Consequences for the application pack

Three things change.

First, the fire statement must be submitted on the form published by the Secretary of State and is a national validation requirement. An application for a relevant building without one is invalid, and the eight or 13 week clock does not start.

Second, the Health and Safety Executive is consulted and its response forms part of the decision. Build the consultation period into the programme and expect comments on principles rather than on detail: site access for fire appliances, water supply for firefighting, evacuation strategy and the implications of the chosen means of escape for the massing.

Third, the fire strategy has to be developed far enough at planning stage to answer those questions. That is a change of sequence from the way many teams worked before 2021, when fire engineering followed planning permission. Where the building is complex, a full fire safety strategy to BS 9991 or BS 9999 may be needed alongside the statement, and schemes with habitable basement levels have their own egress questions, set out in our piece on safe egress from habitable basement rooms.

Who authors the statement for this building type

Someone with fire-engineering competence, and for student accommodation that competence should include experience of cluster-flat compartmentation and of managed buildings with a single operator.

This is a legal requirement rather than a preference. The fire statement sits within the Building Safety Act 2022 framework, and the Building Safety Regulator will read it as a professional document. An AI-assisted draft can structure the statement to the form's headings and flag the facts and calculations it needs, and it is a starting point for a fire engineer rather than a substitute for one.

Sequencing against the prior approval route

Article 9A attaches to applications for planning permission. A scheme delivered through a permitted development prior approval route therefore does not pick up the Gateway One consultation automatically, which has led some developers to treat the two routes as equivalent on fire safety. They are not.

Two points to hold onto. Several classes in Schedule 2 of the General Permitted Development Order carry their own information requirements touching fire safety, so read the class conditions rather than assuming silence. And the Gateway Two and Three regime under the Building Safety Act applies to a higher-risk building however the planning consent was obtained, so avoiding Gateway One avoids a consultation, not an obligation.

This is general guidance, not legal advice; check the position with your local planning authority or a qualified professional before relying on it. A fire statement and a fire safety strategy require an author with the necessary fire-engineering competence, and PlanScope's draft is a starting point for that professional.
