Covering Bognor Regis

Homes in the South East
The South East has a lot of 1930s and post-war semi-detached housing, well suited to rear extensions and hip-to-gable loft conversions, alongside period properties in conservation areas that need a more careful design.
What is a house-to-flat conversion?
A house-to-flat conversion divides a single house into two or more self-contained flats, each with its own front door, kitchen and bathroom. It always needs planning permission and full building regulations approval, particularly for fire separation and sound insulation between flats.
- Planning application and layouts to space standards
- Fire separation and sound insulation between flats
- Separate electrics, heating and metering
How much should I budget for a house-to-flat conversion?
Typical ranges for house-to-flat conversions. Ground conditions, access and specification move the final figure, which we fix in writing before work starts.
Priced on survey.
How is a house-to-flat conversion approved in Bognor Regis?
Projects in England go through two separate checks. Planning (or confirmation that the work is permitted development) comes from the district, borough or unitary council, and building regulations approval comes from the council’s building control team or a registered building control approver. Where work touches a shared wall or digs near a neighbour’s foundations, the Party Wall etc. Act 1996 applies.
Dividing a house into flats always needs planning permission in England.
What should I think about before starting?
- Sound insulation between flats is tested on completion.
- Mortgage lenders and freehold arrangements need early legal advice.
How does the project run?
- Start with a conversation. A short call or the online form is enough for us to understand what you want to build.
- Survey at your house. We look at the existing structure, services and access, and agree what the design needs to achieve.
- Design and fixed price. You get drawings and a written price for the agreed specification before anything is ordered.
- Build and hand over. Our teams build to the programme, building control inspects, and you get the completion paperwork at the end.
