Play space assessments and who prepares them

The play space assessment author question has a split answer. The child yield arithmetic and the policy compliance case belong to the planning consultant. The design of the space, its layout, surfacing, planting and relationship to overlooking homes, belongs to a landscape architect. The equipment specification and its post-installation inspection belong to someone qualified against the playground equipment standards. Councils ask for one document and it takes three sets of hands.

Schemes get into trouble when the whole thing is treated as a planning exercise and a play area appears on the landscape plan at the end.

What the assessment has to demonstrate

Three things, in order.

That the expected child population of the development has been calculated from the unit mix and tenure, using a recognised method. That the quantity of play space provided meets the policy standard for that population. And that the space provided is in the right place, at the right age range, accessible to the children who will use it, and deliverable with a funded maintenance arrangement.

Most submissions do the first two and treat the third as a plan annotation. The third is where objections come from, because a residents' group can see immediately that the doorstep space is a strip of grass beside the bin store.

Add a fourth element on larger schemes: phasing. Play space delivered with the final phase is play space unavailable to the first 200 households for four years, and councils increasingly condition delivery against occupation triggers.

Child yield and where the numbers come from

Child yield is derived from the housing mix, the tenure split and published yield rates for the area. In London the Greater London Authority publishes a population yield calculator that takes the unit schedule and returns an expected child population by age band, and Policy S4 of the London Plan then requires at least 10 m² of play space per child.

Outside London the method varies. Local plan policies and supplementary guidance set their own standards, sometimes expressed per dwelling, sometimes per child, sometimes as a quantum of open space per thousand population, and benchmark standards published by national play and outdoor sport organisations are frequently referenced.

Whatever the source, show the working. A table of unit types, tenures, yield rates, resulting child numbers by age band and the play space requirement that follows is three lines of arithmetic and it prevents an argument. Where a yield rate has been adjusted, say why.

Age band matters as much as the total. Provision for under-fives is a different thing, in a different location, from provision for twelve year olds, and a single equipped area does not satisfy both.

Landscape architect against planning consultant

The division of labour is clearer than in many disciplines.

A planning consultant establishes the policy requirement, runs the yield calculation, and writes the compliance narrative. That work needs familiarity with the adopted plan and any supplementary guidance, and nothing more specialised.

A landscape architect designs the space. That means the layout, levels, boundary treatment, surfacing, planting, seating, shade, sightlines from surrounding homes, and the routes children take to reach it. Chartered membership of the Landscape Institute is the usual marker. This is the part that decides whether the space is used or avoided, and it is not a drawing exercise that a planner should attempt.

On larger schemes a play specialist sits alongside both, particularly where natural or landscape-led play is proposed rather than standard proprietary equipment. The same distinction between a statutory label and a practical one runs through what competent person means in planning legislation.

Equipment standards and inspection competence

Play equipment and its surfacing are governed by the European standards adopted in the UK: BS EN 1176 for the equipment and BS EN 1177 for impact attenuating surfacing.

The post-installation inspection is the one that gets forgotten, and it is the one an insurer will ask for. Write it into the specification and into the maintenance obligation, not into a covering letter.

Free height of fall, impact area extents and surfacing depth are the details that cause the most retrofits. They constrain the plan area required for each item, which means the equipment layout has to be tested against the available space before the planning drawings are fixed, rather than after.

Inclusive play and who advises on it

An equipped area that a wheelchair user can reach but not use is a recurring failure, and the public sector equality duty under the Equality Act 2010 puts the question in front of the decision maker.

Inclusive provision is about the whole sequence: an accessible route from the homes, a level or gently graded entrance without a kissing gate, ground surfaces a wheelchair or walking frame can cross, items that can be used at ground level, seating for carers, and quiet space away from the busiest equipment for children who find noise difficult.

Get specialist advice where the scheme is large or where the local plan has an explicit inclusive play requirement. Where it does not, the landscape architect should still be asked to state how the design addresses it, because an officer will ask and a generic sentence will not do.

Maintenance, adoption and the funding route

Decide early who ends up owning the space, because the answer changes the design.

Local authority adoption brings the authority's own specification, which may exclude certain surfacing types or equipment, and usually a commuted sum calculated on its formula. A management company arrangement gives more freedom on specification and puts the cost into the service charge, which has consequences for the affordable housing provider and sometimes for mortgage lending. A third route, a commuted payment towards off-site provision, only works where an existing facility within a reasonable distance has capacity.

Whichever route is chosen, set out the inspection regime, the replacement cycle for equipment, and the funding source in the assessment. An Open Space Assessment covering the wider provision should be consistent with it.

Scoping against the local policy requirement

Read the adopted policy before commissioning anything. The variables that change the scope are the standard itself, whether it is expressed per child or per dwelling, the age bands recognised, the distance thresholds for each band, whether off-site contributions are accepted, and whether the authority publishes a yield calculator or expects one to be justified.

Where the policy is silent or dated, say so and adopt a recognised national benchmark with the reason. An assessment that quietly picks the most convenient standard available is easy to spot.

A Play Space Assessment drafted against the right policy, with the yield working shown, gives the case officer something to check rather than something to query. PlanScope can structure that draft and flag the site facts it does not hold, and reviewers who can check the design side are listed in the professional directory.
