Covering Swindon
Our coverage around Swindon (SN1, SN25, SN26) also includes Calne, Wantage and Chippenham.
Homes in the South West
In the South West, matching local stone, render or slate is often the main design question, and conservation areas and listed buildings are common in historic towns.
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
- Fire separation and sound insulation between flats
- Separate electrics, heating and metering
What is the guide price for a house-to-flat conversion in Swindon?
What house-to-flat conversions typically cost. These are guide ranges; the written quote for your house replaces them.
Priced on survey.
Do you need permission for a house-to-flat conversion in Swindon?
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. Councils assess flat sizes (many use the nationally described space standard), parking, bins, cycle storage and the effect on family housing supply.
What should Swindon 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.
From first call to completion
- Send us the details. Give us a postcode, a rough idea of size and some photos, by phone, form or the guide price tool.
- We visit and measure. A surveyor checks the house, the boundaries and the ground, and discusses what is realistic.
- 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.
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 Swindon 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.
