Homes in Gwent
Housing in Wales ranges from terraced streets in the valleys and older industrial towns to stone-built homes in rural areas and modern estates around the cities.
What goes into an upward extension?
An upward extension adds a new storey on top of an existing house, most often turning a bungalow into a two-storey or chalet-style home. It can double the floor area without using any of the garden.
- Planning and building regulations checks under Welsh rules
- Structural survey of walls and foundations
- Full fit-out of the new rooms
How much should I budget for an upward extension?
What bungalow and upward extensions typically cost. These are guide ranges; the written quote for your house replaces them.

What approvals does an upward extension need in Wales?
Welsh projects need planning clearance from the council under Welsh rules, building regulations approval under the Welsh approved documents, and party wall notices where the work affects a neighbour’s wall or foundations.
Adding a storey in Wales needs planning permission. We prepare the application with drawings showing how the new roofline fits the street.
What can affect an upward extension?
- Some bungalow foundations need strengthening before a storey can be added.
- Neighbours’ light and privacy are the main planning tests.
How does the project run?
- 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.
Your questions answered
Can I add a first floor to my bungalow?
Often yes, if the walls and foundations can carry the load and planning allows. We check the structure first.
Do we need to move out?
Often for part of the job, while the roof is off and the new floor is formed. We plan this with you.
Can you visit a house in Chepstow 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.
