A nursery in a converted office floor

Day nursery planning permission in an office is often not needed at all. A day nursery falls within Class E(f) of the Use Classes Order and an office falls within Class E(g)(i), so moving from one to the other is a change within the same class and is not development. The hard parts are elsewhere: outdoor play space, the 20 minutes either side of 9am when forty cars want the same kerb, and the Building Regulations consequence of putting under fives on a second floor.

Start with the title and the planning history, not with the use class table.

Whether the change needs permission at all

Article 3 of the Town and Country Planning (Use Classes) Order 1987, as amended in 2020, provides that a change of use within the same class is not development. Class E now bundles shops, financial and professional services, cafes and restaurants, indoor sport, medical and health services, crèches and day nurseries, offices, research and development and light industrial.

So the use change itself is free. Three things can take that freedom away.

A condition on the existing permission that restricts the use to offices only. This is common on 1980s and 1990s business park consents and on anything granted as part of an employment allocation. The remedy is an application under section 73 to vary the condition, or a fresh full application, and the council will test the proposal against its employment land policies.

An Article 4 direction removing the relevant permitted change in that area. These exist in central London and in some town centres.

Physical works. New windows, an external fire escape, an enclosure around a play terrace, plant on the roof and signage are all separate questions from the use, and any of them can need permission or advertisement consent.

Conditions, leases and the things that are not planning

Read the lease at the same time. A permitted user clause limiting occupation to office use will stop the scheme whatever the planning position says, and a landlord's consent is usually needed for the alterations.

Also check whether the building is in a Class E use at all. A floor last used as a dental surgery, a bank branch or a gym is probably in Class E. A floor last used as a school, a nursery run as part of a church hall, or a place of assembly may be in Class F1 or F2 or sui generis, and the change into a day nursery is then a material change of use needing permission.

Outdoor play space and the alternatives

This is the issue that most often kills an upper floor conversion, and it is driven by childcare regulation rather than planning policy.

The Early Years Foundation Stage statutory framework requires providers to give children access to an outdoor play area or, where that is not possible, to plan and take outdoor activities on a daily basis. The framework also sets indoor space standards, measured per child by age band, which determine your registered capacity far more precisely than any planning policy will.

In practice the options for an office floor are:

1. A dedicated external terrace or roof terrace, which raises overlooking, balustrade design and noise questions and usually needs permission.
2. An enclosed part of the surrounding car park or forecourt at ground level, with a secure route down from the nursery floor.
3. Daily use of a nearby park or recreation ground, documented in the operational statement with the route, the staff ratios and the crossing points.

Option three is acceptable to registration and is frequently accepted in planning, but it needs to be written down properly. A case officer who reads "children will visit local open space" with no named destination and no route will ask for more. Name the park, state the walking distance, describe the crossing, and say what happens in bad weather.

Drop off and collection as a highway problem

Nursery traffic is unusual in two ways. It is sharply peaked, and it coincides exactly with the morning highway peak and the school run.

A 60 place nursery does not generate 60 trips spread over a day. It generates a cluster of arrivals between about 7.45am and 9.15am and a slightly longer spread in the afternoon, with each arrival involving a parked vehicle for five to ten minutes rather than a kerbside stop. That is the number the highway authority cares about, and the TRICS database is where trip rates for day nursery uses are taken from.

What usually resolves it:

An office floor usually comes with an allocated parking ratio that the nursery inherits, and converting part of that allocation to short stay drop off bays is the move that tends to satisfy a highway officer. A short transport statement covering arrival profile, parking supply and the drop off layout is normally enough at this scale, and a full assessment is rarely proportionate. The published article on play space and drop off in commercial units goes further into the ground floor variant of the same problem.

Noise from children and how it gets assessed

Children's play noise is not industrial or commercial sound, so BS 4142 is the wrong tool and an acoustician who reaches for it first is signalling inexperience.

The assessment that works uses absolute levels. Predicted levels at the nearest noise sensitive facade from the outdoor play area at full occupancy, compared with internal guideline levels for habitable rooms, with the Planning Practice Guidance on noise and the Noise Policy Statement for England concepts of significant observed adverse effect applied as judgement rather than as a pass mark. Hours of use matter more than the peak level, because play noise during a weekday afternoon reads very differently from the same level at 7am.

Where a terrace sits above residential windows, mitigation is usually a combination of an acoustic balustrade, a cap on the number of children outside at once and a condition on the hours the terrace can be used. A noise impact assessment is worth commissioning before you submit if any dwelling faces the proposed play space, because retro fitting a solution after an objection is far harder.

Means of escape, Part M and the kitchen

Putting a nursery on an upper floor is a material change of use under the Building Regulations, and the fire strategy is the thing that most often forces a redesign.

Evacuation of children who cannot self rescue, from above ground level, in a building with a single stair, is a genuine engineering problem. Approved Document B travel distances and the provision for assisted escape will dictate whether a second means of escape is needed, and a new external stair almost always needs planning permission. Part M accessibility applies on change of use, as does Part E for sound insulation between the nursery and any other occupier.

If meals are cooked on site rather than brought in, kitchen extraction becomes a planning matter. A ventilation and extraction statement covering the duct route, termination height and odour control is standard where the flue runs up an elevation.

Registration, and what to submit

Ofsted registration under the Childcare Act 2006 runs separately and in parallel. Registration tests staffing, space per child, safeguarding and the outdoor provision. Planning permission does not guarantee registration and registration does not guarantee planning permission, and the two are assessed by people who never speak to each other.

Where an application is needed, the pack is usually a planning statement, an operational statement covering sessions and capacity, a transport statement, a noise assessment where there are nearby dwellings, drawings showing the play space enclosure and any external alterations, and an extraction statement if there is a kitchen.

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