A village defined by water
Between the marina on the Hamble and the Swanwick Lakes nature reserve nearby, water is a big part of Swanwick's character — the mix of established housing and newer waterside development gives a range of garden sizes and ground conditions across the village.
Fareham Borough Council planning
Swanwick sits within the Sarisbury parish area of the Borough of Fareham, so Fareham Borough Council is the authority for planning permission and permitted development here, not Eastleigh Borough Council.

Ground conditions near the water
Given the marina and former clay-pit lakes nearby, some parts of Swanwick have heavier or wetter ground than drier inland plots, which can influence whether a concrete pad or a screw-pile base makes more sense — a local installer will assess this on a visit.
Frequently asked questions
Does Swanwick's marina affect garden room plans nearby?+
Not directly for most inland gardens, though plots closer to the water can have different drainage or ground conditions worth flagging to the installer you're matched with.
Which council handles planning in Swanwick?+
Fareham Borough Council, since Swanwick falls within the Borough of Fareham rather than Eastleigh.
