An ageing village and 400 new homes
Arlen village has 3,200 residents. Its median age is 52, compared with 40 nationally. The primary school roll has fallen from 210 to 168 in five years, the single GP surgery has one part-time nurse and no resident doctor, and the hourly bus service was cut to two journeys a day last year. A developer has applied to build 400 homes on 18 ha of greenfield land. Thirty-five per cent would be affordable, and the developer promises a new shop unit and a contribution to school places. The district housing target requires 1,100 new homes over five years, and Arlen is one of four candidate sites. Opponents say the village lacks sewer capacity, the lane to the main road has no pavement, and new residents would commute by car. The planning committee must decide whether to approve, refuse or approve with conditions. The local plan allocates no employment land here.
1. Assess the likely impacts of the 400 homes on the village's population structure and service demand.

Using an average household size of about 2.3, 400 homes could add roughly 920 people, an increase of nearly 29% on 3,200. The age structure is likely to be younger than the village average, because affordable and family homes attract younger households. That could raise the primary school roll: if the scheme yields about 0.3 children per home, it could add around 120 pupils, taking the roll from 168 to about 288. That may exceed the school's capacity, even with the developer's contribution. The GP surgery would also face higher demand from 920 extra residents, and the two-a-day bus would be inadequate. Sewer capacity and the unlit lane are infrastructure constraints. However, new families could counter the ageing trend and support the shop. The impact is therefore mixed: likely pressure on school, health, transport and drainage, but possible demographic renewal if infrastructure is upgraded.
2. Recommend whether the committee should approve, refuse or approve with conditions. Justify your decision.

Approve with conditions. Refusal is difficult to defend when the district needs 1,100 homes in five years, Arlen is one of only four sites, and 35% affordable homes would meet a clear need. The school roll is falling, so new families could help sustain it. However, approval without conditions would place unacceptable pressure on sewer capacity, the lane, the GP surgery and the bus. Conditions should require a sewer upgrade before occupation, a pavement and safe crossing on the lane, a bus service contribution, and a health contribution or a plan for GP capacity. The affordable homes should be phased with market homes, and the shop unit should not be allowed to remain empty. The committee should also require a travel plan because employment land is not allocated locally and car commuting is likely. This is a balanced judgement: the strategic housing need justifies approval, but the identified infrastructure deficits must be resolved first.
3. Explain how the committee could test the developer's claim that the scheme will support the school and shop.
Read the worked answer
For the school, the committee should not rely on the developer's promise but should apply the local pupil-yield rate to the number and mix of homes. It should compare the resulting roll with the school's published capacity and check catchment data. For the shop, it should estimate available expenditure from the new households and compare this with the turnover threshold for a viable convenience store, taking account of existing shops nearby. A household survey or comparison with similar developments would improve the estimate. The committee should also check whether the shop unit is a planning obligation or merely an intention, and whether the school contribution is sufficient for additional classrooms. This tests the claim against independent evidence and exposes uncertainty.
