Opportunity Area frameworks and the weight they carry

An Opportunity Area Planning Framework is not part of the development plan, and that single fact determines how you use one. It is a material consideration, which means a decision maker must take it into account but is not obliged to follow it where the development plan and other considerations point elsewhere. Applicants in London routinely cite a framework as though it were policy, and officers routinely correct them.

Opportunity Areas themselves are a London Plan designation. Policy SD1 identifies them as the capital's main reservoir of brownfield development capacity, with indicative figures for homes and jobs set out in the plan's annex, and it asks for development within them to be co-ordinated rather than brought forward site by site.

What an Opportunity Area is in the London Plan

The designation marks places with the potential to accommodate substantial new housing and employment floorspace, usually because they have existing or planned public transport capacity, large sites in few ownerships, or both. The London Plan gives each one an indicative capacity rather than a target, and the distinction matters when an objector argues that a scheme exceeds the area's allocation.

What the designation does in practice is shift the starting point. Within an Opportunity Area, intensification is expected, taller buildings are more likely to be acceptable in principle, and a scheme that under-uses its site will face the question of whether it optimises capacity. The approach to optimising site capacity under the design led method in Policy D3 is where that question gets answered.

The designation does not suspend anything. Heritage duties, flood risk policy, the industrial land policies and amenity standards all apply inside an Opportunity Area exactly as they do outside one.

How a framework is prepared and adopted

A framework is prepared by the Greater London Authority, usually with the borough or boroughs involved, and sometimes with a development corporation or a transport body. It typically sets out a spatial strategy for the area, indicative capacity by sub-area, infrastructure requirements, design and tall building principles, phasing expectations and a delivery mechanism.

The stages it passes through determine its weight.

That last row is where the real difference lies. A framework adopted by the borough as supplementary planning guidance has been through the borough's own consultation and adoption process, and an officer will give it more weight than a document published by the Mayor alone. Check which applies to your area before writing the policy section, because the two situations call for different wording.

The weight a framework carries in a decision

Section 38(6) of the Planning and Compulsory Purchase Act 2004 requires applications to be determined in accordance with the development plan unless material considerations indicate otherwise. In London the development plan means the London Plan together with the borough's local plan and any neighbourhood plan. A framework sits outside that, alongside other material considerations.

The practical consequences are these. A framework cannot override a development plan policy, so a scheme that conflicts with an adopted local plan policy is not rescued by compliance with a framework. A framework can, however, supply the evidence and the spatial reasoning that justifies a departure, particularly on height, density and land use mix, and that is its most useful function for an applicant.

It also works against you. Where a framework identifies a site as suitable for employment-led development and you propose residential, the framework becomes the document the objectors quote. Deal with it directly rather than ignoring it. An application that engages with the framework's reasoning and explains why the site has moved on since it was written is far stronger than one that pretends the framework does not exist.

And be careful with indicative capacity figures. They are estimates prepared at area level, often several years earlier, and they are not a cap. Officers know that. Objectors sometimes do not.

Infrastructure, capacity and phasing expectations

Frameworks exist partly because Opportunity Areas need infrastructure that no single site can fund. Expect the framework to identify transport interventions, school and health capacity, open space and street improvements, and sometimes utilities reinforcement, and to indicate how each is to be funded.

Three mechanisms usually appear. The Mayoral Community Infrastructure Levy applies across London and funds strategic transport. The borough's own levy, where it charges one, funds local infrastructure according to its charging schedule. And site-specific requirements come through section 106 obligations, which have to satisfy the statutory tests of being necessary to make the development acceptable, directly related to the development, and fairly and reasonably related in scale and kind.

Phasing is the part applicants underestimate. Where a framework ties development capacity to a transport intervention, a scheme that comes forward ahead of that intervention has to show that its own trip generation can be accommodated on the existing network. That is a Transport Assessment question, and on a large scheme in an Opportunity Area it is usually the question that decides the number of units.

Utilities deserve a mention of their own. Electrical capacity constraints have become a real programme risk in parts of London, and a framework that assumes network reinforcement is not the same as a distribution network operator that has budgeted for it. Ask early.

Affordable housing and the threshold approach

The London Plan's threshold approach to affordable housing applies in Opportunity Areas as elsewhere. A scheme meeting the threshold level of affordable housing, delivering it in the required tenure split and meeting the other criteria, follows the fast track route and is not required to submit a viability assessment. A scheme below the threshold follows the viability tested route, with a formal appraisal and usually an early or late stage review mechanism.

On public sector land and on sites involving the release of industrial land, the threshold is set higher. Frameworks sometimes state a local expectation above the London Plan threshold, and boroughs often have their own local plan target that sits above it too. Where those three figures differ, the development plan figures govern and the framework expectation is a material consideration.

The practical advice is to decide the route before the design is fixed, because the fast track route is worth a great deal in programme terms and the unit mix needed to achieve it affects the plan. An Affordable Housing Statement should set out the route taken, the tenure split, the habitable room or unit basis of the calculation, and the review mechanism offered.

Where site allocations sit alongside

Many Opportunity Areas also contain site allocations in the borough's local plan, and those allocations are part of the development plan. An allocation therefore carries more weight than the framework, and where the two differ the allocation governs. What a London site allocation changes for an applicant is a separate question and worth understanding alongside the framework position.

The common sequence in practice is that a framework is published, the borough then prepares or reviews its local plan, and the allocations that emerge reflect the framework with local modifications. Where the local plan is older than the framework, the framework is the more current statement of intent but the weaker document in law. Say so plainly in the planning statement rather than glossing over it.

Using the framework in a planning statement

Four paragraphs do the job, and they should appear early in the policy section of the Planning Statement rather than buried in an appendix.

1. Identify the framework by its full title and publication date, and state its status, including whether the borough has adopted it as supplementary planning guidance
2. Set out the framework's principles that are relevant to the site, quoting sparingly and citing the section
3. Demonstrate accordance principle by principle, with cross-references to the drawings and the technical documents
4. Identify any departure, explain why, and point to the evidence that has changed since the framework was prepared

Step 4 is the one that wins arguments. A framework prepared before a transport scheme was cancelled, or before the industrial land market changed, or before a neighbouring site was consented at a greater height, is out of date in specific ways you can evidence. Name them.

Do not quote indicative capacity figures as though they were approvals, and do not describe a framework as policy. Officers read a lot of planning statements, and the ones that get the status of a document right are the ones they trust on everything else.

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