Double-storey extensions in Welshpool

Double-storey extensions for homes in Welshpool and the surrounding parts of Powys, designed around your house and built by our teams under a single written contract.

Covering Welshpool

Our coverage around Welshpool (SY21) also includes Newtown, Oswestry and Shrewsbury.

Because Powys covers a wide area, we confirm availability after the first call and include any travel costs in the written quote rather than adding them later.

Homes in Powys

Welsh homes include long terraces built into hillsides, stone cottages and modern estates, and sloping sites often shape how and where an extension can go.

What goes into a double-storey extension?

A double-storey extension adds new rooms on both the ground and first floor in one build, typically a larger kitchen or living space downstairs and an extra bedroom or bathroom above. Because the roof and foundations are shared, the cost per square metre is usually lower than a single-storey extension.

  • Planning and building regulations checks under Welsh rules
  • Structural engineer’s design and calculations
  • Joining the new first floor to the existing landing

How is a double-storey extension approved in Welshpool?

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.

Most two-storey extensions in Wales need householder planning permission from the council. We prepare and submit the application and deal with any questions from the planning officer.

What can affect a double-storey extension?

  • The new roof is tied into the old one, so roof tiles and ridge details need to match.
  • The first-floor link can mean moving a bathroom or reshaping the landing.

How does the project run?

  1. Start with a conversation. A short call or the online form is enough for us to understand what you want to build.
  2. Free site visit. We measure up, look at access, drains and the structure, and talk through options and budget.
  3. Price and paperwork. The design is priced line by line, and we submit the planning and building control applications.
  4. Build and hand over. Our teams build to the programme, building control inspects, and you get the completion paperwork at the end.
