Five houses on a paddock behind a village street

Five dwellings on a paddock behind a village street is a minor application, determined in eight weeks, and it needs roughly eleven documents rather than the three a single extension needs. This walkthrough follows an illustrative scheme from the settlement boundary argument to the biodiversity gain condition. The site, the figures and the outcome are illustrative and composed to show the sequence, not a record of a real decision.

The pattern repeats across England: a field behind a row of houses, access through a gap in the frontage, a parish that is divided, and a council whose five year housing land supply is contested.

The site and its policy position

Assume a 0.42 hectare paddock, grazed by two horses, behind a street of 19th century cottages and post-war bungalows. Access would come through a gap between two houses, over land the applicant owns. The field is bounded by a hawthorn hedge on three sides, with four mature ash and one oak along the roadside boundary.

The adopted local plan places the site outside the settlement boundary by about 40 metres. There is a made neighbourhood plan. The site is in Flood Zone 1 but sits within a critical drainage area identified by the lead local flood authority.

That combination sets the shape of the application. The scheme is not allocated, so the case is built on the development plan read as a whole under section 38(6) of the Planning and Compulsory Purchase Act 2004, then on material considerations.

Settlement boundary and the housing supply argument

Being outside a settlement boundary is not fatal. It means the scheme conflicts with the plan's spatial strategy, and the application has to explain why permission should still be granted.

Three arguments usually carry the weight. First, the functional relationship of the site to the village: footway connection, distance to the shop, the school and the bus stop, measured and stated. Second, whether the authority can demonstrate a five year supply of deliverable housing sites, because where it cannot, the National Planning Policy Framework engages a presumption in favour of sustainable development that shifts the balance. Third, the physical containment of the site, which is what distinguishes rounding off from sprawl.

Get the housing land supply position from the council's own published statement and quote its figures rather than estimating them. If the position is marginal, say so. An application that overclaims on supply loses credibility on everything else, and the arithmetic in a larger case such as nine dwellings on a village edge site works the same way.

The neighbourhood plan matters here too. A made plan is part of the development plan, and if it allocates sites or sets a design code, the application has to answer it directly.

Access and visibility onto the village street

The gap between the two cottages is 5.8 metres wide in the illustrative scheme. That is enough for a 4.8 metre carriageway with a service margin, which is the first thing the highway authority checks.

Visibility is the second. On a 30mph street the authority will look for splays measured from a set-back point in each direction, and the splay has to sit on land the applicant controls or on highway land. Where a hedge or a wall sits inside the splay, the drawing must show it removed or lowered, and the applicant must be able to do that lawfully.

Internal layout follows. Five dwellings generate a short private drive, and the authority will want a turning head sized for a refuse vehicle or a bin collection point within 25 metres of the highway, parking at the local standard, and cycle storage. Manual for Streets is the reference most highway authorities still work from for residential streets of this scale.

Ecology, trees and biodiversity net gain

A grazed paddock reads as poor quality grassland, which is good news for the metric and still needs survey work. The ecology sequence on a site like this runs: a Preliminary Ecological Appraisal with an extended walkover, then targeted survey only where the appraisal finds a trigger.

Hedgerows are the usual trigger. A species-rich hedge, or one with a ditch and standard trees, scores well under the statutory metric and is expensive to lose. Keep the hedges, design the access through the existing gap, and the metric becomes manageable.

Mandatory biodiversity net gain applies to small sites of this kind, with a minimum 10 per cent uplift, a biodiversity gain plan approved by the authority after permission, and 30 years of management secured. A Biodiversity Net Gain Assessment using the statutory metric has to be completed by a competent person under the Environment Act 2021 regime. An AI-assisted draft is a starting point for that professional and not a substitute for them.

The five roadside trees need a survey to BS 5837:2012, root protection areas plotted on the layout, and an arboricultural impact assessment where any part of the works falls inside those areas. Survey the trees before the layout is fixed, because moving a plot by three metres at sketch stage is free and moving it after validation is not.

Survey seasons set the programme. Emergence surveys for bats run between May and September, reptile surveys between April and October, and a breeding bird constraint applies from March to August. A scheme that reaches the ecologist in October can lose a season.

Drainage and the critical drainage area

Inside a critical drainage area the authority will expect surface water discharge restricted to the greenfield rate, with attenuation sized for the one in 100 year event plus a climate change allowance taken from the current Environment Agency figures.

For a paddock, infiltration is the first option to test. Dig trial pits, record the infiltration rate, and if it works, soakaways serving each plot with permeable paving to the drive is the simplest answer. Where clay defeats infiltration, the fallback is attenuation with a controlled discharge to a ditch or sewer, and the discharge consent from the receiving body becomes a programme item.

A Drainage Strategy covering the existing regime, the proposed system, the design storm, the rates and volumes, exceedance routes and the maintenance arrangements answers the lead local flood authority's standing questions. Foul drainage needs its own answer, with written confirmation of capacity from the sewerage undertaker where the connection is to a public sewer.

The full document pack

The illustrative application was submitted with the following.

1. Application forms, the ownership certificate, the agricultural holdings declaration and the fee.
2. Location plan at 1:1250 with the site edged red and other land in the same ownership edged blue.
3. Existing site plan, topographical survey and tree survey plan.
4. Proposed site layout, with levels, parking, bin and cycle stores, and the visibility splays.
5. Floor plans and elevations for each house type, plus two street scene elevations showing the proposal against the existing frontage.
6. Planning Statement with the policy case and the planning balance.
7. Design and access statement. At five dwellings outside a designated area this is not required by the procedure order, and the validation list asked for one anyway.
8. Preliminary ecological appraisal and the biodiversity metric output with the small sites assessment.
9. Arboricultural impact assessment and tree protection plan.
10. Drainage strategy with infiltration test results and foul capacity confirmation.
11. Transport statement covering trip generation, access geometry and parking.

A single self-build plot needs a lighter pack, and the comparison with a self-build plot on a garden site shows where the extra documents come from as unit numbers rise.

The obligations and conditions agreed

Five dwellings sits below the national affordable housing threshold of ten units, so no on-site provision was sought in the illustrative case. The council was a Community Infrastructure Levy charging authority, so the levy applied at the residential rate for the parish, with the self-build exemption available to one plot on the correct form before commencement.

A short section 106 agreement secured off-site contributions towards primary education and open space, together with a monitoring fee. The biodiversity gain condition is deemed to be imposed on the permission by Schedule 7A to the Town and Country Planning Act 1990, so the gain plan had to be approved before development began.

Other conditions covered materials, the tree protection plan, the drainage details, construction hours, a construction management plan, electric vehicle charging and the removal of permitted development rights on two plots closest to the boundary.

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