Walkthrough: church hall to a day nursery

This is an illustrative walkthrough rather than a real case. It follows a 1930s church hall in an inner suburb, used for Sunday school, a weekly toddler group and occasional lettings, being converted to a 48 place day nursery open 7.30am to 6pm on weekdays. No fabric is being extended. Everything that makes the application difficult is about use, hours, outdoor space and the fifteen minutes either side of 9am.

A day nursery falls within Class E(f) of the Use Classes Order, which covers the provision of a creche, day nursery or day centre. The hall does not, so the conversion is a material change of use and needs planning permission.

The lawful use and the class the hall sits in

The first job is to establish what the hall lawfully is, and the answer is rarely as obvious as the name on the door. A hall used for public worship or religious instruction, or in connection with such use, falls within Class F1. A hall whose principal use is as a meeting place for the local community falls within Class F2. A building used for a genuine mixture of unrelated purposes may be sui generis.

That classification matters because it decides whether any permitted development route exists. There is a right under Part 3 of the General Permitted Development Order allowing a building in Class E to become a registered nursery through prior approval, and a parallel right for agricultural buildings. There is no equivalent right from Class F1 or F2 to Class E(f), so a full application is required. Check the current Order before relying on either position, because Part 3 has been amended repeatedly.

In the walkthrough, the evidence for the lawful use comes from the original 1931 permission, the parish letting diary for the last ten years and rate records. The diary shows worship-related use for most of the week, which supports F1. Where the evidence had been ambiguous, an application for a Lawful Development Certificate for the existing use under section 191 of the Town and Country Planning Act 1990 would have been the sensible first step, because arguing about the baseline during a change of use application wastes the determination period.

One further point. The church intends to keep using the hall on Sunday mornings. Shared use raises the question of whether there is one planning unit with a mixed use or two separate uses, and the application should describe the arrangement precisely rather than leaving it to a condition.

Hours, places and staff numbers

Three numbers drive the whole assessment: opening hours, the maximum number of children on site, and the number of staff. Fix them before anything is commissioned, because every technical document depends on them.

The walkthrough uses 48 places, 12 staff, 7.30am to 6pm Monday to Friday, with no weekend or evening operation and a two week closure in August. Those figures then feed the trip generation, the noise assessment, the internal space calculation and the sanitary provision.

Registration requirements are separate from planning and often confused with it. The Early Years Foundation Stage statutory framework sets minimum indoor floor areas per child, which vary by age band, and requires providers to give children access to outdoor play space or, where that is not possible, to plan outdoor activities daily. Satisfying the registration requirements does not grant planning permission, and obtaining planning permission does not satisfy the registration requirements. Both have to be worked through, and the indoor area calculation often sets the maximum number of places before any planning policy does.

Outdoor play space and the area expected

The hall has a 220m² yard to the rear, currently hardstanding with a bin store, bounded on two sides by garden fences of terraced houses.

The registration framework does not set a fixed outdoor area per child, but local plan policies and supplementary guidance sometimes do, and some authorities apply a standard drawn from older government guidance. Check the adopted policy for the authority rather than assuming a figure, because the range between authorities is wide and the number may be expressed per child on site or per child outdoors at one time.

In the walkthrough the yard is adequate for a rota rather than for all 48 children at once, so the application proposes a maximum of 20 children outdoors at any time, with a timetable. Making that offer in the application, rather than waiting for the officer to impose it, converts a vague anxiety about intensity into a condition everybody can live with.

The design also does three things to the yard: it relocates the bin store to the street frontage behind a screen, it introduces soft landscaping along the boundary with the gardens, and it sets the main play area as far from the shared boundary as the geometry allows. All three are mitigation and all three cost less than acoustic engineering.

Drop-off and collection

Nursery traffic is unusual in two respects. It is concentrated into very short peaks, and it coincides almost exactly with the highway network's own morning peak. A nursery with 48 places generates a modest daily total and a brutal fifteen minute one.

The evidence pack for this walkthrough includes a Transport Statement with trip generation drawn from a recognised trip rate database for the use class, a parking survey of the surrounding streets covering the morning peak on three weekdays, an assessment of the existing waiting restrictions, and a staff travel plan. The approach to transport evidence has much in common with a school expansion and the transport evidence, though the trip profile is sharper and the dwell time shorter.

Two measures do most of the work. Staggered session start times spread the arrivals across half an hour rather than ten minutes. And a managed drop-off arrangement, with staff meeting children at the gate so that parents do not park and walk in, reduces the dwell time per vehicle from several minutes to under one.

Where the street has no capacity at all, the honest answer is a reduction in places or a different site. An application that claims 48 children will arrive without affecting a narrow residential street with no restrictions will not be believed by the highway authority.

Noise from children's play

Children's play noise is the objection that arrives in every one of these applications, and it is the one most often assessed badly. The standard method for industrial and commercial sound, with its corrections for tonality and impulsivity, is not designed for children playing and produces results that overstate or understate depending on how it is misapplied.

The defensible approach measures the existing background in the gardens behind the site over a representative period, predicts the play noise level at the same positions from the proposed numbers and the yard geometry, and compares the two in absolute terms as well as relative terms. It then reports the result against external amenity guidance rather than against an industrial standard, and says plainly what the increase is during the periods when children are outdoors.

A Noise Impact Assessment prepared this way also lets you test mitigation properly. In the walkthrough, a 2.4m close-boarded acoustic fence with a dense mass per unit area along the shared boundary, combined with the 20 child limit and a timetable restricting outdoor use to two hours in the morning and two in the afternoon, brings the predicted levels within a range the environmental health officer accepts. Councils usually expect a suitably qualified author for noise work, and professional review is strongly advised.

Internal alterations and escape

The internal works are modest: a partition to create three rooms by age band, a new accessible toilet, a nappy change area, a milk kitchen and a staff room. None of that needs planning permission in itself, but it all appears on the plans because it fixes the capacity.

The building control issues are larger than the planning ones. A nursery is assessed for means of escape on the basis of its occupancy and the age of the occupants, with travel distances and door widths following from that, and a hall with a single entrance at one end will usually need a second final exit. Sanitary provision, accessibility under Approved Document M, and food hygiene registration for the milk kitchen all follow.

Resolve the escape strategy before the planning drawings are finalised, because a second final exit in the rear elevation changes the external appearance and the relationship with the yard, and a door that appears after permission needs an amendment.

The pack submitted and the conditions offered

The application comprised existing and proposed plans and elevations, a site plan showing the yard and boundary treatments, the transport statement and parking survey, the noise assessment, a Planning Statement setting out the use class analysis and the policy case for a community facility and childcare provision, and a short management plan covering sessions, staffing and the outdoor timetable. The full set of report types that a change of use like this can draw on is listed across the 66 PlanScope report types.

The conditions offered with the application were specific: hours of operation, a maximum of 48 children, a maximum of 20 children outdoors at any one time, outdoor use restricted to stated periods, the acoustic fence to be installed before first use, a travel plan to be implemented and reviewed, delivery and refuse collection times, and retention of the boundary landscaping. Offering conditions is not a weakness. It is how you keep control of the wording.

This is general guidance, not legal advice. Check the position with your local planning authority or a qualified professional before relying on it.
