Extensions in and around Stornoway
We cover Stornoway and the postcode districts HS1. 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.
Planning rules that apply in Stornoway
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.
The planning position for a specific Stornoway address depends on its history and any designations, which is why we check it at the first visit.
Building close to a public sewer needs the agreement of Scottish Water, which we check during design.
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.
What we take care of
- Energy and glazing checks, including whole-house calculations if needed
- Structural calculations for beams, lintels and foundations
- Building regulations drawings and written specification
- Completion certificate on sign-off
- Inspection bookings throughout the build
