Double-storey extensions in Newtown

Homeowners in Newtown can get double-storey extensions from one company: the design, the paperwork and the building work sit with us rather than with three separate firms.

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

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 is included in a double-storey extension in Newtown?

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.

  • Measured survey, design and planning drawings
  • Foundations, steelwork, brick and block walls, roof
  • Joining the new first floor to the existing landing

How is a double-storey extension approved in Newtown?

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.

Most two-storey extensions in Wales need householder planning permission from the council.

What should Newtown homeowners check first?

  • Side extensions close to a boundary are often set back or stepped down so they do not create a terraced effect.
  • Neighbours’ light is assessed using the 45-degree guide many councils use.

What are the steps?

  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. We build it. Work follows an agreed programme, with inspections at each stage and a final sign-off.
