FAQ - Loft conversions west Sussex
Do I need planning permission for a loft conversion ?
Most loft conversions fall under Permitted Development and don’t require planning permission, as long as you stay within volume limits and don’t alter the roof height.
However, you may need permission if:
- Your property is in a conservation area.
- You plan a mansard or large hip-to-gable conversion.
- You want to extend beyond permitted roof volume allowances.
- We can advise during a free survey.
How much does a loft conversion cost ?
Prices vary based on size and style, but typical local ranges are:
Velux loft conversion: £25,000–£40,000
Dormer loft conversion: £40,000–£70,000
Hip-to-gable loft conversion: £55,000–£80,000
Mansard loft conversion: £65,000+
Every home is different, so we provide itemised, fixed quotes.
How long does a loft conversion take?
Most loft conversions in Bognor, Felpham, and surrounding areas take 4–8 weeks, depending on complexity.
Dormers and hip-to-gable conversions usually take longer than simple Velux builds.
Will a loft conversion add value to my Bognor Regis property?
Yes. A professionally built loft conversion can add 15–25% to the value of homes in Bognor Regis, especially where space is limited or extra bedrooms increase market appeal.
What types of loft conversions work best for homes in Bognor Regis?
The most common styles locally include:
- Rear dormer conversions – ideal for semi-detached and terraced homes
- Hip-to-gable conversions – popular for 1930s and chalet-style homes
- Velux conversions – cost-effective for roofs with good height
- L-shaped dormers – great for larger Victorian or extended properties
We recommend based on your roof structure and planning rules.
Will my loft conversion meet building regulations?
Yes. We provide free, no-obligation surveys across Bognor Regis, Chichester, Felpham, Aldwick, Pagham, Arundel, and surrounding West Sussex areas.
How much head height do I need for a loft conversion?
Generally, you need at least 2.2m of height at the highest point of your loft.
If your roof is slightly lower, structural options (like lowering ceilings or raising the ridge) may be available.
Can you convert lofts in conservation areas around Bognor Regis?
Yes, but regulations are stricter. Areas near Adwick, Pagham, Felpham, and parts of central Bognor require additional planning considerations.
We can handle all design adjustments and planning applications for you.
Will a loft conversion cause much disruption?
We aim to minimise disruption by using scaffolding access wherever possible. Many homeowners remain living in the property throughout the build.
Do you offer free surveys and quotes in the Bognor Regis area?
Generally, you need at least 2.2m of height at the highest point of your loft.
If your roof is slightly lower, structural options (like lowering ceilings or raising the ridge) may be available.

Designing Your Loft Conversion
Designing your loft conversion involves thoroughly assessing every aspect of the existing roof structure to establish any necessary initial repair works. Loft conversion companies should always inspect the loft space before offering indications of loft conversion costs since reinforcements may be imperative to ensure you will obtain building regulations approval and have addressed all the fire safety requirements.
For example, we at Swanbourne construction will assess the existing roof slope, roof trusses, and quality of the roof structure before making recommendations, making sure first-floor habitable rooms below have sufficient weight-bearing supports and beams.
From there, our in house loft conversion designers will get to understand your aspirations and what you’d like your loft space to look and feel like. We can discuss varied options such as a Velux loft conversion, hip-to-gable extensions to raise the head height or a mansard loft conversion where you wish to improve the extra space available dramatically.
Our quotations are obligation-free and provide itemised detail, helping you track and manage your loft conversion cost and make informed decisions about which design to proceed with.
