Stondon homes: 115 allowed with drainage safeguards

The Lower Stondon scheme overcame landscape objections, but detailed design and a strategic foul water scheme still require council approval.

Up to 115 Stondon homes have won outline planning permission on land west of Hurricane Avenue in Lower Stondon, Bedfordshire. Inspector H Miles allowed appeal 6009682 on 15th October 2026, overturning Central Bedfordshire Council’s refusal of the proposal.

The permission includes affordable housing, self and custom build provision, public open space and access. It concerns an open field adjoining existing housing, so it will change the village edge. Detailed layout, scale, appearance and landscaping remain for later approval rather than being settled by this decision.

I would read this as a housing approval with important work still to do on drainage. The Stondon homes were allowed despite moderate landscape harm, but a strategic foul water scheme must be approved before development starts. The decision does not establish that the homes can simply connect to the existing treatment works without further assessment.

Why the Stondon homes passed the planning balance

The full Inspector’s decision identifies application CB/25/01015/OUT and the appellants as Rainier Developments Ltd, Mr WA Parrish and Mr WK Parrish. A hearing took place on 16th June 2026, followed by a site visit the next day.

The field lies outside Lower Stondon’s settlement boundary, with farmland beyond its northern and western edges. Existing development adjoins two sides. Public footpaths provide views of the site, and the Inspector accepted that replacing the open field with housing would erode its countryside qualities.

New planting would help screen the development over time, but would not remove its effects, especially from nearby footpaths. The harm was assessed as moderate and localised. The proposal conflicted with local policies seeking to protect landscape character and respond to the natural setting.

Against that harm, the Inspector considered the substantial benefits of new housing, including affordable and self-build provision. The parties agreed a 3.93-year supply of deliverable housing sites for the purposes of the appeal, identifying an unmet need.

The Stondon homes also directly adjoin the settlement and were found physically well related to it. Infrastructure contributions and other arrangements were secured through a planning agreement. These factors were important to the national policy route supporting development outside settlements to address evidenced unmet need.

Thirty per cent affordable housing secured

The decision records that the planning agreement would secure 30% affordable housing and a minimum of 10% serviced plots for self-build and custom housing. The affordable housing policy mix was 72% social or affordable rent and 28% intermediate tenure.

I would keep those percentages separate from a final schedule of individual homes. This is an outline permission for up to 115 dwellings. The detailed mix and design still have to be worked through within the permission, conditions and agreement.

The Stondon homes also bring publicly accessible open space and ecological benefits. The decision records submitted calculations indicating around 14% gain in habitat units and 22% in hedgerow units, alongside the statutory biodiversity gain requirements and long-term securing arrangements.

The planning agreement includes contributions towards education, healthcare, libraries, sport and allotments. Not every requested contribution was accepted. The Inspector was not satisfied that the evidence justified funding towards relocation and expansion of an ambulance hub, so that request was not included in the balance.

Why foul drainage needs further approval

Shillington Water Recycling Centre was a central concern. The decision records evidence that it was already operating over capacity, with no upgrade planned in the investment period running to 2030. Additional flows through that works would risk worsening water quality on the evidence before the Inspector.

During the appeal, evidence emerged that Letchworth Water Recycling Centre could accommodate flows from the proposed growth. The parties agreed that a foul drainage condition was needed, but disagreed over whether it should name a specific connection serving Letchworth.

The Inspector chose a strategy-based condition. Future investment could change the available options, so the point of connection should be determined when the details are considered. This leaves a decision for the council at that stage; it does not approve an unrestricted connection to Shillington.

Condition 12 requires approval of a strategic foul water strategy before development commences. No dwelling may be occupied until the drainage works serving it are completed and operational. The Stondon homes must thereafter drain in accordance with the approved strategy.

Traffic, accessibility and the village edge

The Inspector considered an estimate of around 71 to 72 additional car trips in the peak hour along Hurricane Avenue, noting that the transport officer thought it might be an overestimate. The additional traffic was not found unacceptably harmful to the wider network, nearby residents or highway safety.

That finding does not remove the requirements for access works and later transport details. A condition prevents occupation before the junction with the existing Hurricane Avenue has been constructed as approved. An updated residential travel plan must also be approved before occupation.

The reserved matters submissions must address housing sizes, space standards and accessibility, including minimum proportions of adaptable and wheelchair adaptable homes. They must also include roads, paths, parking, boundaries and a rights of way scheme, with at least one hard-surfaced connection to Footpath 4.

What happens after the appeal

For residents following the Stondon homes, the next planning stage will provide much more information about their detailed appearance and layout. The 21-condition schedule also covers drainage, lighting, ecology, archaeology, contamination, sustainability and other matters that need to be addressed at the specified stages.

The Inspector’s conclusion was that the substantial benefits would not be “substantially outweighed” by the moderate adverse effects under the national policy assessment. That is the reasoning behind permission, rather than a finding that the scheme has no disadvantages.

I would check subsequent submissions against the actual conditions, rather than assume the appeal resolves every design or infrastructure question. Our Alfold homes report offers another recent example of a housing approval in which sewerage safeguards remained important to delivery.
