Houses in Salisbury and what they need

Salisbury's medieval centre, around the Cathedral and the Close, gives way to Victorian terraces in Fisherton, interwar semis along the Castle Road corridor, and modern estates at Old Sarum and Bishopdown. Salisbury falls under Wiltshire Council rather than Dorset, and we cover the city as part of our wider service area.

Victorian terraces in Fisherton and the city centre

Fisherton Street and the surrounding streets have long runs of Victorian terraced houses with narrow rear plots. Side-return extensions and single-storey rear additions work well here, creating a kitchen-diner without using up the garden. We design for the typical party wall configurations found in these terraces, including shared chimney breasts and staggered rear walls.

Castle Road and Harnham

The Castle Road corridor, Harnham and Churchfields have a mix of 1920s to 1960s semis and detached homes on wider plots. Two-storey extensions adding a bedroom above and living space below are common here. We design layouts that keep the established rooflines and setbacks while working within Permitted Development limits or under a Householder application.

Old Sarum and Bishopdown

Salisbury's newer developments at Old Sarum, Bishopdown and Hampton Park are built on regular plots with modern construction, and extensions here generally benefit from standard PD rights. We design additions that add a kitchen-diner or garden room flowing into the rear garden.

Planning permission for extensions in Salisbury

Salisbury falls under Wiltshire Council, a separate unitary authority from the Dorset councils that cover most of our service area. The planning process and policies are broadly similar, with local distinctions around the Cathedral Close, the city centre conservation area, and the proximity to Salisbury Plain.

How Wiltshire Council handles extension planning

Wiltshire Council processes Householder Planning Applications within the standard eight-week period. The application fee is set nationally and is the same at every council in England, and the Planning Portal lists the current fees. Salisbury's city centre conservation area restricts PD rights for properties within its boundary, and several streets are subject to Article 4 Directions that remove additional PD entitlements.

Restrictions near Salisbury Cathedral

The Cathedral Close is one of the most architecturally significant areas in England, and extensions to properties within or near the Close face close scrutiny. The wider city centre conservation area extends across much of the medieval street grid. We check your property against Wiltshire Council's conservation area maps and listed building register before recommending a design approach.

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.

Do you cover Salisbury even though it is in Wiltshire?

Yes. We work with Salisbury homeowners and regularly submit planning applications to Wiltshire Council. The free project review and Layout Ideas Pack are for Poole, Bournemouth, Christchurch and the area around them, so we check your postcode before booking.

Do I need planning permission for an extension in Salisbury?

Most extensions in Salisbury's suburban areas fall under standard Permitted Development. Properties within the city centre conservation area or near the Cathedral Close may need full planning permission. We check your property's constraints with Wiltshire Council before recommending a way forward.

Which council handles planning in Salisbury?

Wiltshire Council handles all planning applications for Salisbury. This is separate from the BCP and Dorset councils that cover most of our other service areas, but the process is essentially the same. The council charges an application fee, set nationally and revised each year, and the Planning Portal lists the current fees.
