A Class MA appeal has removed a one-person occupancy restriction from 25 of the 66 approved flats in a Gloucester office conversion. Planning Inspector B Phillips allowed the appeal on 6 November 2026 and deleted a condition that would have limited specified one-person flats to one occupier.
The case concerns Beaufort House on Brunswick Road, where Gloucester City Council had granted prior approval on 26 June 2026 for offices to become 66 self-contained homes. The developer challenged condition 4, rather than the principle of the conversion.
The Class MA appeal matters well beyond Gloucester because it distinguishes national minimum space standards from permanent controls on who may actually live in a home. The Inspector found the condition neither necessary nor reasonable, while leaving the remainder of the prior approval and other legal requirements in place.
Why the Class MA appeal succeeded
The scheme was approved under Schedule 2, Part 3, Class MA of the Town and Country Planning (General Permitted Development) (England) Order 2015. The right allows qualifying commercial premises within Use Class E, including offices, to change to Class C3 homes following a prior-approval process. It is not the same as full planning permission.
Gloucester imposed condition 4 on specified flats identified in its decision notice. The condition required each of those homes to be occupied by no more than one person as their sole or principal residence. The council said this protected future residents because the flats met the nationally described space standard for a one-bedroom, one-person dwelling.
Inspector Phillips considered whether that restriction was reasonable or necessary for living conditions. The answer depended on the role of the nationally described space standard, rather than a general view about whether smaller flats should have few occupants.
The standard classifies dwelling sizes by bedrooms and bedspaces when determining whether new accommodation meets specified minimum internal dimensions. Its paragraph 6 explains that this is for assessment when designing homes and seeking planning consent. It explicitly says the classification does not imply actual occupancy
.
In the Class MA appeal, the Inspector reasoned that a space-standard classification does not itself justify fixing the number of people who can ever live in a dwelling. The approved plans had already met the relevant Class MA requirements. The condition was not required to make development acceptable, and the decision removed it completely.
An important inconsistency also troubled the Inspector. Other approved flats, containing two to four bedrooms, did not have equivalent limits on occupants. The council had not demonstrated why these particular one-person units needed a lifetime restriction when the other flats did not.
A space standard is not an occupation licence
One-person accommodation still has to comply with the space standards that apply at the decision stage. The decision does not permit developers to bypass minimum floorspace, building safety or other requirements. It deals with a different question: whether compliance with the space-standard assessment can then be converted into a continuing personal-occupancy limit.
The Inspector found that the standards were intended for assessing new dwelling layouts, not intended to ensure that occupancy levels are set in perpetuity
. That distinction is worth keeping in mind whenever conditions are proposed for studios, compact flats or schemes with a mix of dwelling sizes.
Under paragraph W(13) of Part 3 of the GPDO, a council can grant prior approval subject to conditions reasonably related to the matters being considered. This is not an unlimited power to add fresh restrictions to permitted development. The familiar tests of necessity, precision, enforceability and reasonableness remain important.
The decision records a suggestion that condition 4 could be modified by referring to the supporting information submitted with the application. However, no alternative wording or explanation was supplied to show why the new condition would meet the tests. The Inspector therefore did not substitute a different occupancy restriction.
Our guide to planning conditions covers the tests that conditions must satisfy. In a Class MA appeal about a condition, it is not enough for an authority to prefer a cautious approach. It must demonstrate that the specific restriction is needed for an issue lawfully within the prior-approval decision.
Heritage and habitats controls still apply
The Inspector also considered matters outside the occupancy dispute. The site is in Gloucester’s Spa Conservation Area, adjoining the Grade II listed Beaufort House. No external alterations formed part of the scheme, and the return to residential use was considered compatible with the area’s historic character.
In those circumstances, the Inspector found no harm to the setting of the listed building or to the character and appearance of the Conservation Area. The decision refers to the duties under sections 66(1) and 72(1) of the Planning (Listed Buildings and Conservation Areas) Act 1990.
There was a separate habitats issue. The site lies within the zone of influence of the Cotswold Beechwoods Special Area of Conservation. Regulation 77 of the Conservation of Habitats and Species Regulations 2017 may therefore require a further application and assessment before development can lawfully begin.
Inspector Phillips said the GPDO and habitats regulations do not prescribe a mandatory order for obtaining prior approval and making a Regulation 77 application. Both sets of requirements must be met before works start where applicable. Approval of one does not replace the other.
This part of the Class MA appeal is particularly relevant where a scheme appears ready to proceed following a positive prior-approval decision. Developers should not confuse removal of an occupation condition with confirmation that all remaining pre-commencement requirements have been discharged.
What Gloucester’s decision means for other conversions
The underlying prior approval still covers the proposed 66 flats. It has not been changed into a free-standing consent for any residential arrangement, nor have the specified floorspace and plans been reapproved at different sizes. Only condition 4, which limited occupancy in identified units, was deleted.
Applicants can reduce the risk of disputed conditions by showing that their layouts meet the relevant space standard and by making clear how each prior-approval matter has been addressed. An appeal may be justified where a council adds controls that go further than the relevant statutory test.
Authorities, meanwhile, should identify the actual planning harm their proposed condition is intended to avoid. A numerical description in a technical standard is not enough by itself to establish that a household larger than that figure would necessarily create unacceptable living conditions.
Planning Geek’s Class MA guidance explains who can use the right, its qualifying conditions and the required prior-approval procedure. It is worth reading alongside the government’s space-standard document, particularly for proposals comprising a substantial number of compact dwellings.
The Class MA appeal offers a useful warning against using conditions as a substitute for carefully applying the eligibility criteria. Once a council has accepted a proposal as meeting the relevant Class MA tests, it must still justify each additional restriction against the limited scope of the prior-approval powers.
