Purpose-built student accommodation, usually shortened to PBSA, is housing designed and managed specifically for students. It commonly combines private bedrooms or studios with shared kitchens, living spaces and facilities for studying, socialising and wellbeing. Unlike a conventional flat or house, occupation is normally restricted to students and the building is managed as a single development. Its planning treatment depends on the particular scheme and the policies applying in the local area.

​

What does PBSA normally include?

 

PBSA can take several forms. A development may contain individual studios with their own kitchen and bathroom, bedrooms arranged in cluster flats sharing a kitchen and living area, or a mixture of both.

​

Larger schemes often include communal study rooms, lounges, laundry facilities, gyms, cycle storage and managed reception or security. Bedrooms are usually let individually for an academic year rather than under a conventional tenancy for an entire flat.

​

PBSA may be developed and operated by a university, a specialist student accommodation provider or an investor working with an operator. It can be provided on a university campus, close to an institution or elsewhere in a location from which students can conveniently reach several universities.

​

How is PBSA different from an HMO?

 

A house in multiple occupation, or HMO, is usually an existing house or flat occupied by several unrelated people who share facilities. Although many HMOs accommodate students, they were not necessarily designed for that purpose and are generally smaller than PBSA developments.

​

PBSA is normally planned, constructed and managed as a complete student housing scheme. It tends to include purpose-designed communal facilities, on-site management and controls over occupation.

 

PBSA can reduce pressure on the conventional private rented sector by giving students an alternative to shared houses. This may allow family-sized homes to remain in, or return to, general residential use. However, the extent of this benefit will depend on whether the accommodation meets students’ needs at a price they can afford.

​

Is PBSA a residential use?

 

PBSA provides accommodation, but it does not automatically fall within the same planning use class as an ordinary house or flat.

​

Conventional homes normally fall within Use Class C3. University halls may sometimes fall within Use Class C2, which covers certain residential institutions. Many commercially operated PBSA developments are treated as a use in their own right, known as a sui generis use.

​

The correct classification depends on the physical accommodation, the way the building is occupied and managed, and the relationship between residents and any educational institution. The description of development and any planning conditions or obligations are therefore important. A change between PBSA and another residential model may require planning permission even where relatively little physical work is proposed.

​

What does national planning policy say about PBSA?

​

The National Planning Policy Framework requires planning authorities to assess and reflect the housing needs of different groups, expressly including students, in their planning policies.

​

National planning guidance says that authorities should plan for sufficient student accommodation, whether it consists of communal halls or self-contained homes and whether or not it is located on campus. Authorities are also expected to engage with universities and other higher education providers to understand their accommodation requirements.

​

National guidance recognises that dedicated student accommodation can release existing homes into the wider housing market or prevent them from being converted into student housing. PBSA can therefore contribute to an authority’s housing land supply and its Housing Delivery Test result, although communal bedrooms are not necessarily counted as equivalent to individual conventional homes.

​

There is no single national PBSA policy prescribing where every scheme should be located, what proportion should be affordable or how many studios it may contain. These matters are principally governed by the relevant local plan and, where applicable, a regional spatial strategy.

​

How is the need for PBSA demonstrated?

 

A planning application will commonly need to show that there is a genuine need for additional student accommodation. The evidence may consider:

​

• the number of students studying in the relevant area;

• projected changes in student numbers;

• universities’ recruitment and accommodation plans;

• the existing supply and pipeline of student bedrooms;

• occupancy and vacancy levels;

• the condition and cost of existing accommodation;

• students’ use of the private rented sector; and

• the suitability of the proposed location for one or more institutions.

 

Headline student numbers are rarely sufficient on their own. The assessment should consider whether the proposed accommodation type, rent level and location correspond with the needs of the students who are likely to occupy it.

​

Some policies require a formal nominations agreement with a university or another eligible body. This gives the institution a right to nominate students for an agreed proportion of the bedrooms. A nominations agreement can help demonstrate that the development is connected to an identifiable source of demand, but the precise requirement varies between areas.

​

What makes a suitable location?

 

PBSA is generally directed towards accessible locations with convenient connections to higher education institutions, public transport, shops and everyday services. A site does not necessarily need to be immediately beside a university if students can reach relevant campuses safely and conveniently.

 

The planning authority will also consider whether the development would support a mixed and inclusive neighbourhood. A substantial concentration of student accommodation may raise concerns about the balance of the local population, the displacement of conventional housing or the character of an area. Conversely, PBSA can support regeneration, bring activity and expenditure into an area and reduce student demand for family homes.

​

The question is therefore not simply whether students can reach a university. It is whether the scale and form of the development are appropriate for the site and its wider neighbourhood.

​

What design issues are important?

 

PBSA must provide a good standard of accommodation despite the relatively compact size of individual bedrooms. Relevant considerations commonly include:

​

• bedroom and communal-space sizes;

• the balance between studios and cluster flats;

• daylight, outlook and ventilation;

• noise and privacy;

• accessibility for disabled students;

• fire safety and emergency evacuation;

• internal and external communal space;

• cycle parking and sustainable travel;

• refuse storage and collection;

• security and safeguarding; and

• arrangements for servicing, arrivals and departures.

 

The quality and usefulness of shared space are particularly important. Small bedrooms cannot be justified simply by providing communal areas elsewhere in a building if those areas are inadequate, inconvenient or unlikely to meet residents’ everyday needs.

​

A management plan will often address staffing, security, maintenance, deliveries, refuse, complaints, student arrivals and departures, and conduct within and around the development.

​

Does PBSA have to provide affordable accommodation?

 

There is no uniform national requirement for affordable student accommodation. The position depends on local and regional policy.

​

In London, Policy H15 of the London Plan establishes specific requirements for PBSA. It seeks the maximum reasonable amount of affordable student accommodation. Schemes can follow the affordable housing fast-track route where they provide at least 35% affordable student accommodation, rising to 50% on certain public-sector or industrial sites.

​

London’s policy also generally requires the majority of bedrooms in commercially developed PBSA to be covered by a nominations agreement with one or more higher education providers. The accompanying guidance says that the nominated bedrooms should include all of the affordable student accommodation.

​

Different requirements apply elsewhere. Some authorities seek affordable student rooms, financial contributions or evidence explaining why the proposal should not provide conventional housing. The adopted and emerging policies for the particular site must therefore be examined carefully.

​

How is student occupation secured?

 

Planning authorities commonly use conditions or a section 106 planning obligation to restrict occupation to students. The controls may define who qualifies as a student, require evidence of enrolment and regulate any use outside the academic year.

​

A section 106 agreement may also secure:

​

• affordable student rents;

• nominations arrangements;

• accessible bedrooms;

• a management plan;

• restrictions on car ownership or parking permits;

• monitoring information; and

• contributions towards local infrastructure.

 

If summer use is proposed for tourists, conference delegates or other visitors, this should be addressed expressly in the application. It should not be assumed that a permission for student accommodation automatically authorises unrestricted short-term visitor accommodation.

​

What are the main planning considerations?

​

A PBSA application is likely to be assessed against the development plan as a whole. In addition to student housing policies, the principal considerations may include land use, housing need, the loss of existing employment or conventional housing, design, heritage, neighbouring amenity, transport, flood risk, energy, biodiversity and infrastructure.

​

The most effective planning case normally connects three elements: evidence of student need, a suitable and accessible location, and an accommodation model that will provide an acceptable living environment. A weakness in any one of these areas can undermine the wider proposal.

​

Key points

 

• PBSA is housing designed and managed specifically for students.

• It commonly includes studios or cluster flats supported by shared facilities and on-site management.

• PBSA does not automatically fall within the same use class as conventional housing.

• National policy requires authorities to consider student housing needs, but detailed requirements are mainly set locally.

• Need, affordability, location, design and the effect on the surrounding housing mix are usually central to the planning assessment.

• Conditions and section 106 obligations commonly secure student occupation, management arrangements, affordable rooms and nominations agreements.

​

When should professional advice be sought?

 

Early planning advice can help establish whether a site is suitable for PBSA, which policies apply and what evidence will be needed. This is particularly important where a proposal would replace another protected use, depart from a housing allocation, require a university nominations agreement or raise questions about affordable student accommodation, viability or the balance of housing in the area.
