The largest town outside Winchester itself
Bishop's Waltham is the largest settlement in the Winchester district outside the city, with a mix of an older town centre and later residential streets spreading out around it. That mix means garden sizes and access vary a good deal from one street to the next.
Planning and the town centre
As with New Alresford, properties close to the Bishop's Palace and the historic town centre may be listed or within a conservation area, which can affect whether a garden room needs formal planning permission. Winchester City Council, which covers the whole of Bishop's Waltham, is the authority to check with.

Groundwork near the River Hamble
Given the town's position near the source of the Hamble, some gardens sit on lower-lying ground, which is worth mentioning to an installer alongside any questions about drainage and the base a garden room will need.
