A growing village
Horton Heath has expanded with newer housing estates in recent years, alongside its older residential streets, giving a mix of modern gardens with more standard proportions and some longer-established plots with more established planting and layout.
Eastleigh Borough Council planning
As part of the Fair Oak & Horton Heath civil parish within the Borough of Eastleigh, the same council that covers Hedge End handles planning here, and the standard permitted development rules for single-storey garden rooms apply.

Newer estates and standard plot sizes
On the newer developments, garden sizes tend to follow fairly standard modern proportions, which usually gives a clear, straightforward basis for sizing a garden room — an installer can confirm what fits once they've seen the plot.
