Daylight to hotel and care home bedrooms

Care home bedroom daylight is assessed under the same BRE good practice guidance that covers flats, because that guidance extends to non-domestic buildings where occupants have a reasonable expectation of daylight, and it names hotels and hostels among them. What changes for a Class C1 or Class C2 scheme is not whether the guidance applies. It is which rooms you assess, what you assess them against, and how much weight a shortfall carries.

A hotel bedroom occupied between 11pm and 8am by someone who is out all day is not the same receptor as a care home bedroom occupied for most of the 24 hours by a resident who cannot easily leave it. Treating them identically, or treating both as though they were flats, produces an assessment that officers discount.

Whether the guidance applies to these uses at all

The BRE guidance on site layout planning for daylight and sunlight sets its own scope. It addresses dwellings and non-domestic buildings where there is a reasonable expectation of daylight, listing examples that include hospitals, hotels and hostels.

Care homes fall within that category comfortably. Residents live there. It is their home, whatever the use class says, and the expectation of daylight is at least as strong as in a flat.

Hotels are more arguable, and the argument is worth having explicitly rather than by omission. A city centre hotel bedroom where the occupant sleeps and leaves is a different case from an aparthotel with extended stays and in-room working. Say which model your scheme is, because it changes the reasonable expectation and therefore the weight of any shortfall.

The guidance is advisory. It is not policy, it says so itself, and it invites flexibility where the circumstances of a site justify it. That flexibility is the space in which most Class C1 and Class C2 schemes are decided.

Bedrooms occupied at night and rooms used by day

Sort the accommodation by when it is used before you model anything.

In a hotel, the bedroom is the principal habitable space and it is used mainly outside daylight hours. The reception, restaurant, bar and any lounge are used during the day but are commercial spaces with their own lighting design, and they are rarely the focus of a planning objection.

In a care home, the picture inverts. Bedrooms are occupied through the day by residents who are unwell, immobile or receiving care in their room. Communal lounges and dining rooms are where mobile residents spend waking hours. Both matter, and the lounge often matters more.

That sorting exercise is the foundation of the assessment, and it is the same discipline described in room use assumptions and how they change results. Get the assumptions wrong and every number after them is answering the wrong question.

Where a scheme is being assessed for its effect on neighbours rather than its own internal daylight, the same logic applies in reverse. A proposal that overshadows a neighbouring care home's lounge windows has a stronger objection against it than one affecting its corridor glazing.

Communal lounges as the sensitive space

On a care home application, model the communal spaces properly and say why.

A lounge used by residents through the day, often seated in fixed positions away from the window, is the space where daylight has the clearest effect on wellbeing. Where the lounge is deep, single aspect and north facing, the assessment should say so plainly rather than reporting a compliant average across the room.

Sunlight matters here in a way it does not for a hotel bedroom. Access to direct sun in a lounge or a garden room, and to the external amenity space, is part of what the building is for. Where the scheme provides a south-facing garden room or conservatory, assess it, and where the layout puts the lounges on the shaded side, expect that to be raised.

Amenity space assessment follows the same rules as for a residential block, and the approach in courtyard blocks and sunlight to shared amenity space transfers directly to a care home courtyard, which is often the only outdoor space residents use.

Corridor-lit rooms and single aspect layouts

Care and hotel buildings tend towards deep plans with rooms either side of a central corridor, because that is efficient and because it shortens staff travel distances. The consequence is that every bedroom is single aspect, with one window, often in a recess behind a bathroom pod.

That recess is the detail that ruins results. A window set back behind an en-suite loses a large part of its sky view, and the effect on internal daylight is larger than the elevation suggests. Where the plan is fixed, the mitigation is in the window: wider openings, higher heads, lighter reveals and pale internal finishes.

Borrowed light from a corridor is not daylight. Do not present a rooflit corridor as a mitigation for a poorly lit bedroom, because it will not be accepted and it damages the credibility of the rest of the assessment.

Where the building has an internal courtyard or lightwell, check the rooms facing it against the rooms facing outwards, and report them separately. Averaging across the two hides exactly the result an officer is looking for.

Operator standards sitting alongside planning

Planning is not the only standard the building has to meet. Care operators and their regulators work to design guidance that treats daylight, outlook and access to outdoor space as part of the quality of the environment, and dementia design guidance in particular emphasises daylight, contrast and orientation.

Those standards are not planning policy and an officer cannot enforce them. They are useful evidence. Where an operator's own requirements exceed the BRE targets in the communal spaces, saying so strengthens a case that the scheme has been designed around resident wellbeing rather than around unit numbers.

The reverse also applies. An application that falls short on daylight to bedrooms and communal rooms, in a building that will be a home to people for years, is hard to defend by pointing at the guidance being advisory.

How officers weigh a shortfall

Three factors decide how much a numerical shortfall costs you.

Which space falls short. A shortfall in a hotel bedroom in a dense town centre is commonly accepted. The same shortfall in a care home lounge is not.

How far below the target, and across how many rooms. A handful of rooms marginally below, in a scheme where the rest perform well, reads differently from a systematic shortfall across a whole elevation.

What the alternative is. Where the constraint comes from an existing building being converted, or from a tight urban site, officers have more latitude than where the shortfall is the product of maximising the room count on an open site. That distinction is the one to address head on in the assessment.

Present the results so a non-specialist can see all three at once. The approach in presenting daylight results a committee can read matters more here than on a residential scheme, because the assessment is already unfamiliar territory for members.

What to submit for a Class C1 or Class C2 scheme

A proportionate submission contains:

1. A statement of which use class the scheme falls in and how the accommodation is actually occupied through the day.
2. A schedule of rooms assessed and rooms excluded, with a reason for each exclusion.
3. The criteria applied, with a justification for using them for this use, including any departure from the residential targets.
4. Results by room and by floor, with the courtyard-facing and outward-facing rooms reported separately.
5. Sunlight results for the communal spaces and the external amenity areas.
6. A mitigation section covering window sizes, reveal depths, internal finishes and layout changes already made.

A Daylight and Sunlight Assessment for these uses is expected by councils to be prepared by a suitably qualified practitioner, and professional review before submission is strongly advised.
