A crossroads village with medieval roots
Cadnam grew up at the meeting point of the old Romsey-to-Ringwood road and the route between Southampton and Fordingbridge, a junction that's still busy today now that the M27 motorway's western end sits right beside the village. The name itself was first recorded in the twelve-seventies.
That long history as a crossroads is part of why Cadnam feels more like a proper village centre than some of the smaller hamlets nearby, even though it sits well within the National Park.
The National Park Authority, not the district council
Cadnam lies within Copythorne parish, entirely inside the New Forest National Park boundary, so the New Forest National Park Authority is the planning authority here rather than New Forest District Council. Anyone planning a garden room should check with the Park Authority directly, since permitted development rights inside the Park are often more restricted than in a district-council area.

A village known for its cricket and its oak
The Cadnam Oak, a well-known boundary tree in local Forest tradition, and a cricket club with roots going back to the late nineteenth century both give the village a stronger sense of identity than its size might suggest.
