Reports for converting an office to a children's nursery

Turning an office into a day nursery usually needs no planning permission for the change of use itself, because both sit inside Class E of the Use Classes Order. Offices are Class E(g)(i) and creches and day nurseries are Class E(f), and movement within a class is not development. That is the easy part. What the council will still want to see are documents about outdoor play space, drop-off traffic, noise, air quality and ground contamination, because those arrive through the physical works, through conditions on the existing permission, and through the environmental health officer rather than through the use class.

Before assuming the free movement applies, read the existing permission. A condition restricting occupation to office use only overrides the class, and that condition is common on business parks.

Whether permission is needed at all

Three checks settle it.

First, the lawful use. If the building has been used as an office and that use is lawful, the Class E position holds. If it was a shop that became an office without permission more than ten years ago, the lawful use is arguable and a Lawful Development Certificate under section 191 of the Town and Country Planning Act 1990 is worth having before you sign a lease.

Second, conditions. Planning permissions frequently restrict use to a named purpose within what is now Class E, and a condition can lawfully do that. Removing it means an application under section 73, which reopens the use question with all the policy tests attached.

Third, an Article 4 direction. Some councils have removed permitted change within Class E in specific areas, and others have directions aimed at particular uses.

Even where the use change is free, the physical works are not. A fenced outdoor play area, a canopy, new doors and windows, a raised deck, signage, a kitchen extract duct, an external fire escape, or anything that changes the external appearance may need permission on its own.

Outdoor play space and its evidence

This is the item that sinks nursery schemes on upper floors and in tight urban sites. The statutory framework for the early years foundation stage requires providers to have access to an outdoor play area or, where that is not possible, to take children outdoors on a daily basis. It also sets internal space standards of 3.5 square metres per child under two, 2.5 square metres for two year olds and 2.3 square metres for children aged three to five.

Those internal figures drive the registered capacity, and registered capacity drives everything else: staff numbers, vehicle trips, noise. Work them out before you take the lease, because a building that yields 40 places rather than 60 changes the business case.

For planning, describe the outdoor provision precisely. Its area, its surface, its enclosure, its boundary treatment, how it is supervised, the hours it is used, and what happens on wet days. Where outdoor space is provided off site through a nearby park, say how children get there and how often, and expect the officer to test it.

Noise from play and from drop-off

Two separate noise sources, assessed in two different ways, and conflating them is the usual mistake.

Plant noise, meaning the kitchen extract fan, the ventilation units and any air conditioning, is assessed against the existing background sound level using the British Standard method for rating industrial and commercial sound. That gives a numerical rating level and a clear answer.

Children's voices are not industrial or commercial sound, and that standard is not the right tool for them. Acousticians assess play noise against the existing ambient environment and by reference to the duration and timing of use, and mitigation is usually about limiting the number of children outside at once, restricting hours of outdoor use, and putting an acoustic fence between the play area and the nearest residential boundary. A Noise Impact Assessment covering both sources, with a management plan attached, answers the environmental health consultation in one go.

Where the nursery adjoins housing, propose the conditions yourself. Hours of outdoor play, maximum numbers outdoors, and a complaints procedure offered up front read better than the same conditions imposed after an objection.

Parking, drop-off and highway safety

Nursery trips are concentrated, short and awkward. Arrivals cluster in the morning peak and departures in the evening peak, both overlapping with commuter flows, and each trip involves a parent parking, walking a child in and signing them over.

A Transport Statement at this scale should give trip generation from a recognised database for a day nursery rather than for an office, because the profiles are completely different. It should show the drop-off arrangement on a drawing, the swept path for a refuse vehicle, visibility at the access, and a parking accumulation exercise across the peak hour rather than a single figure.

The honest position on many town centre sites is that there is no on-site drop-off. Where that is so, say it, and propose a staggered session start, a travel plan and a named member of staff managing the gate. Officers accept that more readily than a drawing showing three bays that could never work.

Air quality and the ground

Children are treated as a sensitive receptor. Where the site fronts a busy road or sits inside an air quality management area, expect to be asked for an Air Quality Assessment looking at exposure at the play area and at the ventilation intakes, with mitigation through intake positioning, filtration and, where possible, moving the play area away from the kerb.

Contamination works the same way. Where children will have access to soft landscaping, bare soil or a planted area, the end use is more sensitive than an office and the assessment has to be redone against the new receptor. A desk study feeding a contaminated land assessment is the starting point, and these reports are expected from suitably qualified and experienced persons working to the relevant British Standard, with professional review before submission. Where the outdoor area is entirely hardstanding with a safety surface over it, the pathway argument is much simpler, and saying so clearly saves a Phase 2 investigation.

Access and inclusive design

The Equality Act 2010 applies to the provider, and Approved Document M applies to the building work. What an officer looks for is step free entry, a buggy store that is actually usable, an accessible toilet and a nappy change facility, door widths and thresholds, and a route from the parking or drop-off to the entrance that works with a pushchair.

None of that needs a separate report on a small scheme. It needs a paragraph in the design statement and dimensions on the drawing.

What to submit, and in what order

1. Establish the lawful use and check for conditions and Article 4 directions before committing to the building.
2. Calculate registered capacity from the space standards, because it drives everything downstream.
3. Book a pre-application meeting and take the capacity figure, the play area proposal and the drop-off sketch to it.
4. Commission noise and, where the road is busy, air quality, since those set the mitigation the design has to carry.
5. Submit the application with the transport statement, the noise assessment and a management plan covering hours and numbers.

The same sequencing logic applies to other Class E health and care uses moving into existing units, as set out in documents a dental or medical practice in a shop needs.

This is general guidance, not legal advice. Use class positions turn on the lawful use and on conditions, so check with your local planning authority or a qualified professional before relying on it.
