Covering Fort William
Our survey diary covers Fort William, including PH33. Island and remote projects are planned individually, with travel, deliveries and accommodation for the team agreed before the survey.
Across Scotland, extensions follow Scottish planning and building standards, including the building warrant process, which we build into the programme from the start.

Do I need planning permission in Fort William?
In Scotland the questions are whether the extension falls within householder permitted development (Classes 1A to 1D) or needs planning permission from the council, and the building warrant, which is required before construction begins and is followed by a completion certificate.
Before any drawing is finalised we check whether the house is listed, in a conservation area or subject to an Article 4 direction.
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.
Building close to a public sewer needs the agreement of Scottish Water, which we check during design.
Applications are decided by your council as planning authority.

From first visit to completion
Visits to Fort William are arranged around travel; we confirm any travel costs in writing before the survey.
Site visit by arrangement
A designer visits, takes measurements and photos, and discusses layouts, budget and timing with you.
Design and approvals
We draw the design, agree it with you and handle planning or permitted development checks and building regulations.
Fixed written price
The price is fixed in writing once the design is settled, with a clear programme and payment stages.
Build and sign-off
The build is managed from start to finish, inspected at each stage and signed off on completion.
Common questions in Fort William
Do you cover all of Fort William?
Yes. We cover Fort William and the surrounding parts of Highlands and Islands. Projects here are taken on by arrangement because of travel, and any travel costs are agreed before the survey.
How long does this take for a Fort William home?
2–6 weeks for drawings, depending on the council and the complexity of the project.
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Fort William, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.
How much do extension plans cost?
Our design packs range from about £1,150 to £5,400 including VAT, from planning drawings only to a full pack with building regulations drawings, structural calculations and 3D views. Council fees are separate.
Do I need an architect?
Not necessarily. For most extensions an experienced designer or architectural technologist is enough. For listed buildings or complex sites an architect’s input can help.
