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 and building regulations checks under Welsh rules
- Separate electrics, heating and metering
- Kitchens, bathrooms and finishes
How much should I budget for a house-to-flat conversion?
Guide prices for house-to-flat conversions, including VAT where it applies. Your fixed price is confirmed in writing after the survey.
Priced on survey.
Do you need permission for a house-to-flat conversion in Ystalyfera?
Planning decisions in Wales are made by the local council, using permitted development rules set by the Welsh Government rather than England’s. Building regulations in Wales have their own approved documents, and the Party Wall etc. Act 1996 applies to work on shared walls and boundaries.
This needs full planning permission from your council in Wales. We prepare and submit the application and deal with the planning officer on your behalf.
What can change the price or programme?
- Each flat needs its own utilities and metering.
- Sound insulation between flats is tested on completion.
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.
- 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.
- Construction and completion. One site lead co-ordinates every trade through to the building control certificate.
