The ground
Boyn Hill Gravel · chalk · Kempton Park Gravel
The village’s mapped centre is on river sand and gravel — the Boyn Hill Gravel — over chalk, ground that typically drains freely. Alluvium is mapped within half a kilometre, towards the river.
Lower Shiplake, where most of the parish’s people live, is mapped on a different river gravel, the Kempton Park Gravel, close to the Thames. Soil types can shift over surprisingly short distances, so a garden in one may not behave like a garden in the other.
Planning
No conservation area · outside the Chilterns
No conservation area lies within a kilometre of the village’s mapped centre, or of Lower Shiplake’s. Shiplake is outside the Chilterns National Landscape, about 0.8 km from the boundary, with only about 3% of the parish inside it. So the standard householder rules apply across most of the parish.
A new fence, wall or gate up to two metres high — one metre next to a road — doesn’t usually need planning permission. In a front garden, new paving over five square metres needs to be permeable, or drain to a lawn or border, to avoid needing permission.
