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 is a house-to-flat conversion approved in Penarth?
In Wales the planning rules, including what counts as permitted development, are set by the Welsh Government, and Welsh building regulations differ in places from England’s. We check both against your house before drawings are finalised, and handle party wall notices where needed.
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?
- Some councils restrict the loss of family houses or limit flat conversions in certain streets.
- Sound insulation between flats is tested on completion.
