Houses in Ferndown and what they need
Ferndown was developed mainly from the 1960s onwards, and the housing stock is dominated by detached and semi-detached family homes on suburban plots, along with a significant number of bungalows, both original builds and dormer conversions. Ferndown has fewer planning constraints than the historic towns of Dorset.
Detached and semi-detached family homes
Ferndown's residential streets, including Ringwood Road, Victoria Road and the estates off Wimborne Road, have 1960s to 1980s detached homes on wide plots. These properties suit single-storey rear extensions creating an open-plan kitchen-diner, or two-storey extensions adding bedrooms above. The regular plot shapes make extensions straightforward. We design layouts that work within Permitted Development limits.
Bungalows and dormer conversions
Ferndown has a high number of bungalows. Many homeowners extend outward at ground level to add living space, or add a rear dormer to create bedrooms above. We design both: ground-floor rear extensions that open the bungalow into the garden, and loft conversions with dormers that stay within PD limits.
New developments and infill sites
Recent developments in Ferndown and West Parley include compact modern homes on smaller plots. An extension to these properties needs careful design to keep adequate garden space and avoid overshadowing neighbours. We work within the tighter constraints of modern estates to deliver useful extra space without complicating the planning position.

Planning permission for extensions in Ferndown
Ferndown falls under Dorset Council. The town has no conservation area designation and very few listed buildings, so standard Permitted Development rights apply to most properties.
What can be built under Permitted Development in Ferndown
Most properties in Ferndown benefit from full Permitted Development rights. A single-storey rear extension can project up to four metres (semi-detached) or six metres (detached) without planning permission. The larger home extension scheme allows up to six metres (semi-detached) or eight metres (detached) via Prior Approval. Loft conversions with rear dormers up to the standard roof-space limit are also PD. We assess your project and confirm whether it qualifies. The council charges an application fee, set nationally and revised each year, and the Planning Portal lists the current fees.
Green Belt at the edge of Ferndown
Some properties on the eastern edge of Ferndown, toward Stapehill and Hampreston, fall within or near the South East Dorset Green Belt. Extensions within the Green Belt must not be disproportionate to the original dwelling. We check your property's Green Belt status with Dorset Council and prepare a supporting statement if a planning application is needed.
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 Ferndown?
Most extensions in Ferndown fall under Permitted Development and do not need planning permission. Ferndown has no conservation area, so PD rights are generally unrestricted. Properties near the Green Belt boundary toward Stapehill may have extra constraints. We check your property and confirm what applies.
How much do extension plans cost in Ferndown?
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.
Can I extend a bungalow in Ferndown?
Yes. Bungalows are common candidates for both rear extensions and loft conversions with dormers, both typically within Permitted Development. We design layouts that combine ground-floor extensions with a future dormer conversion, if you want to phase the work.
Which council handles planning for Ferndown?
Dorset Council is the planning authority for Ferndown. 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.
