Covering Welshpool
Our coverage around Welshpool (SY21) also includes Newtown (12 miles to the south-west) and Oswestry.
Projects in Powys are taken on by arrangement, and any travel and accommodation costs for the team are shown openly in the quote.
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 do you get with a garden annexe?
We design annexes as permanent buildings with proper foundations, insulation and services, and we prepare the planning case showing how the annexe will be used as part of the main home. Connections for water, drainage and power are planned from the start.
- Design and planning application
- Brick, block or timber-frame structure
- Heating, hot water and electrics
How much should I budget for a garden annexe?
Typical ranges for garden annexes. Ground conditions, access and specification move the final figure, which we fix in writing before work starts.
| Garden annexes | Guide price incl. VAT |
|---|---|
| Standard specification | £2,400 to £2,900 per m² |
| Good specification | £2,900 to £3,400 per m² |
| High specification | £3,400 to £3,900 per m² |
What approvals does a garden annexe need in Wales?
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.
In Wales an annexe with sleeping accommodation needs planning permission, usually with a condition tying it to the main house.
What should Welshpool homeowners check first?
- The annexe normally has to remain part of the main household, not let as a separate home.
- A level threshold and wider doors make the annexe suitable for later life.
From first call to completion
- Tell us about the project. Call, use the guide price tool or send the form with a few photos and a postcode.
- 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.
- We build it. Work follows an agreed programme, with inspections at each stage and a final sign-off.
