Part of Romsey Extra
Crampmoor isn't a civil parish in its own right; it falls within the Romsey Extra civil parish, and Test Valley Borough Council is the planning authority covering the hamlet.
No extra heritage layer
No confirmed conservation area applies to Crampmoor, so a garden room here is likely to sit under the standard permitted development rules rather than any extra heritage layer, though it's always worth confirming the specifics with an installer.

A short trip from Romsey
