Covering Billingham
We work in Billingham (TS23) and the places around it, including Stockton-on-Tees, Middlesbrough and Thornaby-on-Tees.

What do you get with 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.
- Feasibility check against local planning policy
- Planning application and layouts to space standards
- Kitchens, bathrooms and finishes
What will a house-to-flat conversion cost?

Do you need permission for a house-to-flat conversion in Billingham?
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.
