Planning rules that apply in Lerwick
In Scotland a small porch can be permitted development (Class 1C) within limits on floor area, height and distance from a road; larger porches need planning permission, and building standards still apply, so we check whether a building warrant is needed.
The planning position for a specific Lerwick 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.
Applications are decided by your council as planning authority.
When a porch extension makes sense
- Homes wanting better kerb appeal
- Busy hallways with no storage
- Front doors that open straight into a living room
Extensions in and around Lerwick
Site visits are available across Lerwick (ZE1). Island and remote projects are planned individually, with travel, deliveries and accommodation for the team agreed before the survey.
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.
From first visit to completion
Visits to Lerwick are arranged around travel; we confirm any travel costs in writing before the survey.
Site visit by arrangement
It starts with a visit to your house to measure, check access and talk through ideas and budget.
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
With the design and specification agreed, you get a fixed written price and a start date.
Build and sign-off
We build it with one project manager, book the building control inspections and hand over the completion certificate.

Yes. We cover Lerwick 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.

On site, typically 2 to 4 weeks once approvals are in place. Before that, allow 2–8 weeks design and approvals.
Do I need building regulations approval in Lerwick?
Yes. Almost every extension needs it, whatever the planning route. In Scotland that means a building warrant before work starts.
How much does a porch cost?
Our guide range is about £3,900 to £14,700 including VAT, depending on size, materials and whether it includes a WC.
