Ponds & Water Features in Windsor, Berkshire
What changes here.
Ponds in Windsor split along the same lines as everything else we build here. On the riverside plots around Datchet and Old Windsor a pond is almost the natural extension of the garden — the water table is already high, and the question is usually how to manage that rather than whether the ground will hold water at all. Further into the town centre and around Eton, where gardens are more established and often period in character, a formal or raised pond tends to suit the setting better than a naturalistic dug pond would.
Ponds & Water Features ground conditions in Windsor
A high water table near the Thames changes how a pond is built rather than whether it can be. Groundwater pushing up from below can lift or distort a liner from underneath if the excavation is not managed properly, so on Datchet and Old Windsor plots we build in a positive outfall and account for the water table in the excavation sequence rather than treating the pond as an isolated hole in the ground. Further from the river, on the more predictable clay found around the town centre and Eton, the more usual concern is a liner settling unevenly on a bedding layer that was not compacted properly.
Planning and permissions in Windsor
A garden pond is ordinary permitted development for the great majority of Windsor gardens. The exceptions worth checking early are conservation area status, common across the town centre and Eton, where any structure visible from a public viewpoint can draw more scrutiny than a rear-garden pond ordinarily would, and tree preservation orders on the mature planting typical of the older gardens here, where digging within a protected root zone needs the council's input before excavation starts. We confirm both at survey before committing to a pond's position and depth.

Ponds & Water Features in Windsor FAQs
In Windsor, specifically.
Yes, and it is one of the more straightforward pond briefs we take on around Datchet and Old Windsor precisely because the ground already holds water so readily. The design work goes into managing that groundwater rather than fighting it — a positive outfall and an excavation sequence that accounts for the water table, rather than assuming the hole will stay dry while we work.
Regularly, particularly around the town centre and Eton where a naturalistic dug pond can look out of place against a period property. A raised, rendered or coped formal pond usually sits better in that setting, and we bring the same attention to detail on the coping and finish that a heritage patio or wall would get.
Usually not for the pond itself, since it sits within permitted development for most gardens. What is worth checking is whether the property is inside a Windsor or Eton conservation area, where anything visible from a public viewpoint gets more scrutiny, and whether any nearby tree carries a preservation order that would affect excavation. We confirm both at survey.
By designing the outfall and the excavation around the water table from the outset rather than discovering the problem once the liner is in. On plots where groundwater sits close to the surface for much of the year, an unmanaged excavation lets water push up under the liner and distort it; we plan the dig sequence and drainage to prevent that rather than trying to fix it after the pond is filled.
