Play space in London: child yield and the area target
London expects at least 10 square metres of playable space per child, with the child population derived from the unit mix. The distance thresholds decide the layout.
Play space in London is calculated, not estimated. The London Plan expects at least 10 m² of good quality playable space per child, the child population is derived from the unit mix using the Greater London Authority's population yield calculator, and the result is an area requirement that has to be found on the layout. On a 200 home scheme with a family mix that can be more than 1,500 m², which is a meaningful share of a constrained site.
Work it out before the massing is fixed. It is a lot harder to find afterwards.
Estimating the child yield
The yield comes from the proposed unit mix, the tenure and the borough. The Greater London Authority publishes a population yield calculator that applies child occupancy rates by bedroom count and tenure, and boroughs expect it to be used rather than a rule of thumb.
Two things drive the answer. Bedroom count, because a three bedroom affordable rented home produces far more children than a one bedroom market flat. And tenure, because the occupancy assumptions differ. A scheme that shifts from a one and two bedroom market mix to a family affordable mix during negotiation can see its play requirement double, and the layout has to absorb it.
Run the calculator again every time the mix changes. The number quoted in the design and access statement at pre-application is rarely the number that applies at submission.
The area target and what counts
The target is at least 10 m² per child, and the argument is almost always about what counts towards it.
Playable space means space designed and laid out for play, not amenity grass that happens to be green. A lawn with a bench is not playable space. A landscaped route with boulders, logs, level changes and planting that children use on the way to school can be, if it is designed that way and the design is shown.
| Counts, if designed for play | Does not count |
|---|---|
| Equipped play areas with safe surfacing | Private balconies and terraces |
| Playable landscape with features designed for play | Amenity lawn with no play function |
| Informal kickabout and ball court areas | Car parking courts and access roads |
| Youth space with seating, shelter and informal features | Space inaccessible to residents of the scheme |
Space that residents cannot reach without crossing a trafficked road, or that is gated against part of the scheme, attracts objections and may be discounted. Tenure-blind access is expected: play space reserved for market housing residents only is not acceptable.
The provision usually sits within the Landscape Strategy, and the areas in that drawing have to be the same areas used in the calculation.
Age bands and distance thresholds
The requirement is split by age group, and each band has a distance expectation measured from the homes it serves:
- Under 5s: doorstep playable space, very close to the front door, generally within about 100 metres and reachable without crossing a road.
- Children of primary school age: local playable space, generally within about 400 metres.
- Young people of secondary school age and above: neighbourhood space, generally within about 800 metres.
The distances are what make the under-5 provision hard on a large site. Primary and youth provision can be consolidated into one good space. Doorstep provision cannot, because every core has to have something within reach, so a scheme with six blocks may need six small spaces rather than one large one.
Design the doorstep spaces into the courtyards at concept stage. Retrofitted, they end up in the leftover corners with the bin stores.
Doorstep playable space
Doorstep space is the category most often done badly, and the reasons are consistent.
It needs to be overlooked by homes, so that parents can see children from the flat. It needs to be out of the wind, which on a tall scheme means checking it against the wind microclimate work rather than assuming. It needs some shade. It needs seating for adults, because an unaccompanied two year old is not the design case. And it needs to be big enough to be usable rather than a token patch of rubber.
Check the current guidance for the minimum usable size expected, and treat it as a floor rather than a target.
Shared, off-site and commuted provision
Where on-site provision falls short, three routes exist and they are not equally acceptable.
Shared provision with an adjoining scheme can work where the space is properly accessible and has capacity for both populations. The evidence has to show the capacity, not assert it.
Use of existing public provision nearby can count where it is within the distance threshold, has spare capacity and is of adequate quality. Boroughs will want an assessment of the existing facility rather than a line on a map, which is the sort of work an Open Space Assessment covers.
A commuted payment is the fallback, secured by section 106 and spent on improving nearby provision. Officers treat it as a last resort for the younger age bands in particular, because a payment does not give a four year old somewhere to play.
Equipment, surfacing and inclusive design
Equipment and impact-absorbing surfacing are covered by the European standards for playground equipment, and the specification should name them. Post-installation inspection by a qualified inspector is normal and worth conditioning.
Inclusive design is not optional. The public sector equality duty applies to the decision, and provision that excludes disabled children will be challenged. That means accessible routes to the space, ground level play items as well as raised ones, surfacing that a wheelchair can cross, and seating with back and arm support.
Natural play features reduce maintenance cost and increase play value, and they need a management plan. A space designed with logs and planting and then mown to within an inch of its life delivers nothing.
Presenting the calculation
The submission that gets approved has one table and one drawing that agree with each other.
The table runs: unit mix, yield by age band, requirement in square metres by age band, provision by location, provision in square metres by age band, and the surplus or shortfall. The drawing shows each space, its area, its age band, and the distance from the furthest home it serves, with the catchment circles drawn on.
A Play Space Assessment brings those together with the policy context and the design rationale. The most common failure is arithmetic: areas estimated from the masterplan rather than measured from the landscape drawing, so the two documents disagree by a hundred square metres and the officer trusts neither.
Where the requirement is squeezing the layout, that is a capacity question rather than a landscape question, and it belongs in the discussion covered by our note on the design-led approach to site capacity.
An illustrative case: a 240 home scheme in an outer London borough, originally mixed one and two bedroom flats with a single central play area of 600 m². The affordable mix moved to 30 per cent three bedroom homes during negotiation, the recalculated yield produced a requirement over 1,400 m², and the central space could not grow. The resolution was three doorstep spaces in the courtyards, an enlarged central area taken from surface parking, and a commuted sum for the youth band directed at an existing park 300 metres away.

Frequently asked questions
How much play space does a London scheme need?
The London Plan expects at least 10 square metres of good quality playable space per child. The child population is derived from the proposed unit mix and tenure using the Greater London Authority's population yield calculator, so the requirement is a calculation rather than a standard per dwelling. Recalculate it whenever the mix changes.
What counts as playable space?
Space designed and laid out for play, including equipped areas, playable landscape with features children use, kickabout space and youth space with seating and shelter. Amenity lawn with no play function, private balconies, parking courts and space residents cannot reach safely do not count. Access has to be available to all tenures.
What are the distance thresholds?
Provision is split by age band with distance expectations from the homes served: doorstep space for under fives very close to the entrance and reachable without crossing a road, local provision for primary age children, and neighbourhood provision for older children and young people at a greater distance. The doorstep band usually drives the layout.
Can I pay a commuted sum instead?
Sometimes, and it is treated as a last resort, particularly for the youngest age band. Shared provision with an adjoining scheme or use of existing public provision within the distance threshold can be accepted where capacity and quality are evidenced. A payment does not give a four year old anywhere to play, and officers say so.
Does play space have to be inclusive?
Yes. The public sector equality duty applies to the decision, so provision that excludes disabled children will be challenged. Design accessible routes to the space, include ground level play items alongside raised ones, specify surfacing a wheelchair can cross, and provide seating with back and arm support for accompanying adults.
