Homes in the Highlands

Scottish homes range from city tenements and sandstone terraces to bungalows and modern estates, and the building warrant process shapes the programme for every project.

What does a garden annexe involve?

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.

  • Building warrant application and completion certificate
  • Design and planning application
  • Foundations and drainage connections

How much should I budget for a garden annexe?

What garden annexes typically cost. These are guide ranges; the written quote for your house replaces them.

Garden annexesGuide 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 Scotland?

Scottish projects follow a different process from England: the council issues a building warrant before work starts and accepts a completion certificate at the end, alongside any planning permission needed. We prepare both applications.

In Scotland an annexe needs planning permission and a building warrant before work starts.

What should I think about before starting?

  • A level threshold and wider doors make the annexe suitable for later life.
  • Council tax treatment depends on who lives there; check with your council.

How does the project run?

  1. Tell us about the project. Call, use the guide price tool or send the form with a few photos and a postcode.
  2. Survey at your house. We look at the existing structure, services and access, and agree what the design needs to achieve.
  3. Design and fixed price. You get drawings and a written price for the agreed specification before anything is ordered.
  4. We build it. Work follows an agreed programme, with inspections at each stage and a final sign-off.

Garden annexes: common questions

Do I need planning permission for a garden annexe?

Usually yes, because people will sleep in it. Outbuilding permitted development does not cover living accommodation.

Can I rent the annexe out?

Usually not without a separate planning permission, because councils normally require it to stay part of the main house.

Do you work in Fort William?

Yes. Fort William is within our coverage for garden annexes, along with nearby Pitlochry and Aviemore.
