Planning and approvals in Highlands and Islands
In Scotland, householder permitted development rules (Class 1A for single-storey ground-floor extensions and Class 1B for extensions of more than one storey) allow some smaller extensions without a planning application, within limits on depth, height and distance from the boundary. Conservation areas and listed buildings are more restricted.
Homes in conservation areas, national scenic areas and listed buildings have tighter rules, so we always check the property's status and planning history before design starts.
In Scotland a building warrant from the council is needed before work starts on almost any extension, and a completion certificate is issued when the work is accepted. Building standards are set in the Scottish technical handbooks.
Scotland has no Party Wall Act. Where work affects a shared wall or a neighbour's land, we agree access, protection and making good with your neighbour in writing before work starts.
Applications are decided by your council as planning authority.
Covering Highlands and Islands
Towns we cover in Highlands and Islands include Inverness, Fort William, Nairn, Thurso, Kirkwall, Lerwick, Stornoway, Dingwall. Scotland's housing includes sandstone villas, terraces and tenements in the cities and plenty of post-war and modern houses and bungalows elsewhere. A building warrant is needed before work starts.
What is included
- Roof with glazing along the side return
- Householder planning application
- Structural design for the corner and openings
- Survey, design and 3D layout options
- Full internal finish or kitchen-ready shell
- Foundations, drainage and any manhole relocation
The corner is where wraparounds succeed or fail. We usually use a single steel goalpost or a corner post hidden in a pier, and set the glazing so the new room reads as one space rather than two boxes.

How the project works
Free site visits on the mainland; island and remote addresses by arrangement, with travel costs agreed first.
Site visit
A designer visits, takes measurements and photos, and discusses layouts, budget and timing with you.
Design and approvals
We produce the drawings and structural design, and manage the approvals so they are in place before work starts.
Fixed written price
We confirm the build price in writing, based on the approved drawings and the finishes you have chosen.
Build and sign-off
We build it with one project manager, book the building control inspections and hand over the completion certificate.
Questions people ask about wraparound extensions
Do I need building regulations approval in Highlands and Islands?
Yes. Almost every extension needs it, whatever the planning route. In Scotland that means a building warrant before work starts.
Do you cover all of Highlands and Islands?
Yes, across the whole of Highlands and Islands. Free site visits on the mainland; island and remote addresses by arrangement, with travel costs agreed first.
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Highlands and Islands, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.
Is a wraparound better than a side return alone?
It adds far more space, but costs more and needs planning permission more often. Our comparison guide sets the two side by side.
How much does a wraparound extension cost?
Our guide range is about £1,960 to £3,630 per m² including VAT. A 25 m² standard-spec wraparound typically lands around £56,000 to £71,500 in Highlands and Islands before design and council fees.
