Covering Southampton
We work in Southampton (SO15) and the places around it, including Totton, Eastleigh and Fareham.
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 goes into 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
- Separate electrics, heating and metering

Priced on survey.
Do you need permission for a house-to-flat conversion in Southampton?
English projects need planning clearance from the local council, building regulations sign-off from building control, and party wall notices where the work is on or near a shared boundary. We prepare and manage all three.
Dividing a house into flats always needs planning permission in England.
What should Southampton homeowners check first?
- Some councils restrict the loss of family houses or limit flat conversions in certain streets.
- Mortgage lenders and freehold arrangements need early legal advice.
What are the steps?
- Send us the details. Give us a postcode, a rough idea of size and some photos, by phone, form or the guide price tool.
- Free site visit. We measure up, look at access, drains and the structure, and talk through options and budget.
- Drawings, approvals, written quote. We prepare the design, apply for the approvals it needs, and give you a fixed price in writing.
- Construction and completion. One site lead co-ordinates every trade through to the building control certificate.
