Houses in Wimborne and what they need
Wimborne Minster has a historic centre built around the Minster church, and the surrounding villages of Colehill, Merley and Corfe Mullen have a wider mix of housing, from Georgian townhouses to 1970s detached estates. This means extension projects here range from heritage-sensitive additions to straightforward modern builds.
Wimborne town centre
The streets around the Minster have Georgian and Victorian townhouses, many within the conservation area. These narrow-fronted properties often suit a rear extension onto a courtyard garden, or an internal reconfiguration that opens up the ground floor without altering the front elevation. We design additions using materials that match the existing stone and brick.
Colehill and Corfe Mullen
Colehill and Corfe Mullen have 1960s to 1980s detached and semi-detached homes on generous plots, well suited to single-storey and two-storey extensions: a kitchen-diner at ground level with an extra bedroom above. Standard Permitted Development rights apply, which keeps the process straightforward.
Villages around Wimborne
The villages around Wimborne, including Pamphill, Shapwick and Sturminster Marshall, have a mix of period cottages and modern homes, often on larger plots. Green Belt designations and countryside policies may apply. We check your property's planning constraints before recommending a design.

Planning permission for extensions in Wimborne
Wimborne falls under Dorset Council, the unitary authority that replaced East Dorset District Council in 2019. The town centre is a conservation area, and several surrounding areas fall within the South East Dorset Green Belt.
How Dorset Council handles extension planning in Wimborne
Dorset Council processes Householder Planning Applications within the standard eight-week target. The conservation area covering central Wimborne restricts Permitted Development rights for cladding, roof alterations and some extensions. Properties in the Green Belt face extra scrutiny, as an extension must not be disproportionate to the original dwelling. We assess your property against both designations before recommending a design.
Green Belt and extensions near Wimborne
Much of the land between Wimborne, Corfe Mullen and Ferndown is designated Green Belt. Extensions to existing homes within the Green Belt are generally acceptable, provided the extension is not disproportionate to the original building. We design within the appropriate limits and prepare a supporting planning statement setting out why the extension is proportionate.
Why homeowners choose us
We combine design and construction experience, so the early layout discussion considers how a home could be altered as well as how it could look. Detailed scope, pricing and programme are agreed separately for each project.

Questions
Do I need planning permission for an extension in Wimborne?
Properties in the Wimborne conservation area have restricted PD rights, so most extensions need full planning permission. Homes in Colehill, Corfe Mullen and surrounding villages generally have full PD rights unless they are in the Green Belt. We check your property with Dorset Council and tell you what applies.

Does Green Belt affect my extension in Wimborne?
If your property is within the South East Dorset Green Belt, an extension must not be disproportionate to the original building. We design within the appropriate limits and prepare the planning statement to demonstrate compliance.
Which council handles planning for Wimborne?
Dorset Council is the planning authority for Wimborne. It replaced East Dorset District Council in 2019. The council charges an application fee, set nationally and revised each year, and the Planning Portal lists the current fees. Applications are typically decided within eight weeks.
