A Hammersmith Class MA appeal has secured prior approval for 24 flats after an Inspector rejected objections about cycle access, sunlight and fire safety. Inspector M Aqbal allowed the appeal on 4 November 2026 against Hammersmith and Fulham Council’s refusal.
The scheme involves converting Lincoln House on Hammersmith Road from commercial, business and service use (Class E) into 24 homes (Class C3). Lincoln Properties Limited appealed following the council’s refusal of application 2025/02819/PMA56.
The Hammersmith Class MA decision matters well beyond this office building. It demonstrates the limits of a council’s scrutiny under permitted development: transport effects, adequate natural light and fire safety can be considered only within the particular tests set out by the General Permitted Development Order (GPDO).
Why the Hammersmith Class MA appeal succeeded
Class MA of Schedule 2, Part 3 of the GPDO allows qualifying Class E premises to become Class C3 homes, subject to its limitations and the prior-approval procedure. The council accepted that Lincoln House met the relevant qualifying-use requirements and that the location was not excluded from the right. The disagreement was about three prior-approval matters, not about whether an office could ever become housing.
The Inspector considered the transport implications, whether all habitable rooms would have adequate natural light, and whether the proposal triggered the Class MA fire-safety prior-approval test. The Inspector assessed the case against the permitted development rules rather than treating it like an ordinary full planning application. Planning Geek’s Class MA permitted development guide explains the wider qualifying tests and restrictions.
The Hammersmith Class MA outcome is an example of why an objection based on a general development plan aspiration cannot automatically defeat a proposal made under a narrowly defined prior-approval route. The applicable GPDO condition still matters, but the council cannot extend that list simply because it would seek more information on a full planning application.
Existing basement parking did not defeat the scheme
Lincoln House sits between Hammersmith Road, Edith Road and Auriol Road, close to frequent public transport and local services. The Inspector recorded a Public Transport Accessibility Level of 6, indicating excellent accessibility. The basement currently provides 23 parking spaces, of which 20 would remain, including two accessible spaces.
The council preferred car-free residential development in such an accessible location. Inspector Aqbal found that retaining some existing basement spaces did not itself demonstrate unacceptable transport effects. The scheme would actually reduce the parking supply by three spaces, and the relevant Class MA question was transport impact, not strict compliance with standards ordinarily applied to new housing.
A unilateral undertaking dated 13 April 2026 also restricts future occupiers, other than eligible Blue Badge holders, from obtaining residents’ parking permits. The Inspector considered it capable of enforcement and relevant to the risk of increased on-street parking demand.
The Hammersmith Class MA appeal therefore shows how an enforceable parking-permit restriction and a credible comparison between existing and proposed uses can be more persuasive than an abstract assumption that any on-site parking is unacceptable.
Cycle access and refuse arrangements were acceptable
The proposed basement would provide 47 long-stay cycle spaces. The council questioned the shared vehicular ramp, its bend and gradient, semi-vertical cycle stands and the detail of lifts and doors. The Inspector observed that existing cycle parking was already in use in substantially the same area.
The Inspector found the ramp relatively short, shallow and sufficiently visible for people entering and leaving it. The single-lane arrangement and constrained manoeuvring space were not ideal, but the evidence did not show unacceptable conflict. Nor did the lack of every requested technical detail establish that the cycle store would be unusable.
Refuse arrangements received similar scrutiny. Plans showed basement storage for three 1,100-litre refuse bins and three recycling bins. The council identified a need for food-waste provision, but did not establish that the basement lacked the room. A management proposal envisaged moving containers to a collection point near the entrance on collection days.
The Hammersmith Class MA ruling did not say that shared ramps or basement refuse stores are automatically acceptable. Rather, the Inspector weighed the actual layout, the existing office building’s operations and the evidence of likely traffic and servicing impacts.
Sunlight guidance is not an absolute prohibition
Natural light was a separate issue. The council accepted that every habitable room met the relevant Building Research Establishment daylight-illumination target. However, 19 rooms across 10 proposed flats fell short of a recommendation for 1.5 hours of direct sunlight on 21 March. Eighteen of those rooms were bedrooms and one was a living and dining room.
Inspector Aqbal distinguished daylight from sunlight and recognised that the GPDO does not make every recommendation in the BRE guidance a rigid legal threshold. The Inspector wrote: The BRE guidance is an important material consideration
. The assessment nevertheless requires planning judgement.
The Inspector also observed that the 1.5-hour recommendation is not framed as a requirement for every bedroom. Bedrooms have different expectations from principal daytime living accommodation. The single affected living and dining room would still receive direct sunlight and meet the daylight target, despite a limited shortfall in the recommended duration.
The Hammersmith Class MA appeal therefore turns on adequate natural light in the actual rooms, not a mechanical pass-or-fail exercise against every separate BRE indicator. This should not be mistaken for a licence to design unacceptably dark homes: the submitted evidence satisfied the Inspector on these particular facts.
The statutory fire-risk condition was not engaged
The council also objected because no fire-safety statement had been supplied. Paragraph MA.2(2)(i) can make fire safety a prior-approval matter, but only where the scheme meets the fire-risk condition in paragraph MA.3, which includes a relevant building-height test.
The council’s own report found Lincoln House below the applicable height threshold, and it accepted during the appeal that the Class MA fire-risk condition was not met. The council nevertheless referred to the London Plan’s fire-safety policy and guidance. The Inspector concluded those documents could not create a prior-approval requirement where the GPDO did not impose one.
That is a procedural planning conclusion, not an exemption from applicable fire safety or building regulations. The Hammersmith Class MA decision illustrates the need to distinguish the statutory prior-approval gateway from separate obligations governing the safe conversion and occupation of a building.
The approval still comes with a completion deadline
The Inspector allowed the appeal and granted prior approval for 24 flats. The Inspector declined to add the further conditions suggested for waste, cycle storage, noise, contamination and flooding, finding them unnecessary or unjustified on the evidence within the prescribed prior-approval matters.
Under Class MA, the conversion must be completed within three years beginning with the prior-approval date. The GPDO also restricts the subsequent use of the building to dwellinghouses and ancillary purposes. Those statutory requirements did not need to be rewritten as conditions in the appeal decision.
For property owners, the immediate lesson is to document the site’s existing lawful use, establish that the building qualifies for Class MA, and provide enough evidence on the actual prior-approval tests. Planning Geek’s change of use planning guide helps distinguish these rights from proposals that require full planning permission.
