Houses in Wareham and what they need
Wareham's Saxon walls enclose a town centre with many listed and period properties. Outside the walls, Stoborough, Sandford and the area toward Wool have a wider mix of post-war and modern housing. What an extension needs depends on whether the property sits inside the walls or in the wider parish.
Properties within the town walls
Wareham's town centre is a conservation area, and many properties are individually listed. An extension here needs Listed Building Consent as well as planning permission, and materials must match the existing structure. We design sympathetic rear extensions and internal reconfigurations that add space without altering the street-facing elevation, and produce drawings for both the planning officer and the conservation officer.
Modern estates and rural properties
Outside the conservation area, homes in Stoborough, Ridge and along the Bere Regis Road sit on larger plots with fewer constraints, where standard Permitted Development rights apply. We design layouts that use the garden depth typical of these properties.

Planning permission for extensions in Wareham
Wareham falls under Dorset Council, the unitary authority that replaced Purbeck District Council in 2019. Planning applications for the town centre conservation area face extra scrutiny, while properties outside the conservation area follow standard Permitted Development rules.
How Dorset Council handles extension planning for Wareham
Dorset Council processes Householder Planning Applications within the standard eight-week target. The conservation area designation covering central Wareham means Permitted Development rights are restricted: external cladding, roof alterations and rear extensions beyond certain limits all need full planning approval. We check your property's designation before recommending a way forward.
Listed building extensions in Wareham
If your Wareham property is listed, any alteration, internal or external, needs Listed Building Consent from Dorset Council. This is a separate application from planning permission and carries no fee, though the assessment is thorough. Our plans include material specifications that show the proposed extension respects the building's character.

Questions
Do I need planning permission for an extension in Wareham?
It depends on your property's location. Homes within Wareham's conservation area have restricted PD rights, so most extensions need full planning permission. Properties outside the conservation area, in Stoborough, Sandford and surrounding villages, generally benefit from standard PD rights. We check your property's status with Dorset Council and tell you what applies.
Can I extend a listed building in Wareham?
Yes, but you will need Listed Building Consent from Dorset Council in addition to planning permission. We produce plans for heritage properties, including material specifications, that satisfy conservation officers.
How much do extension plans cost in Wareham?
Start with a free project review. If it makes sense to go ahead, the next step is the Layout Ideas Pack, done remotely or in person. If your property is listed or in the conservation area, we include heritage-sensitive design notes.
Which council handles planning applications for Wareham?
Dorset Council is the planning authority for Wareham. It replaced Purbeck 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. We handle the submission process, quoted after the review.
