Covering Eastleigh
We work in Eastleigh (SO50, SO97) and the places around it, including Southampton, Winchester and Totton.
Homes in the South East
Many South East homes are inter-war or post-war semis and detached houses with room for rear and side extensions, while historic town centres and villages bring conservation area and listed building controls.
What does a house-to-flat conversion involve?
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.
- Separate electrics, heating and metering
- Kitchens, bathrooms and finishes
- Bin, cycle and amenity space works
How much does a house-to-flat conversion cost in Eastleigh?
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.
Do you need permission for a house-to-flat conversion in Eastleigh?
In England we deal with the council’s planning team for permission or a lawful development certificate, with building control (the council or a registered building control approver) for inspections, and with neighbours under the Party Wall etc. Act 1996 where it applies.
Dividing a house into flats always needs planning permission in England.
What can affect a house-to-flat conversion?
- Sound insulation between flats is tested on completion.
- Mortgage lenders and freehold arrangements need early legal advice.
What are the steps?
- Tell us about the project. Call, use the guide price tool or send the form with a few photos and a postcode.
- Free site visit. We measure up, look at access, drains and the structure, and talk through options and budget.
- Price and paperwork. The design is priced line by line, and we submit the planning and building control applications.
- We build it. Work follows an agreed programme, with inspections at each stage and a final sign-off.
What people ask before starting
How much does a flat conversion cost?
It varies too much to give a reliable guide figure, so we price each one on survey. The reduced 5% VAT rate can apply where the number of dwellings changes.
How long does a conversion take?
Typically 16 to 30 weeks on site after approvals.
Can you visit a house in Eastleigh to quote?
Yes. After a short call we arrange a site visit to measure up and agree what the design needs to do, then send a written price.
