Covering Oban

Across PA34, we can visit, measure and advise. 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 and approvals in Oban

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.

Before any drawing is finalised we check whether the house is listed, in a conservation area or subject to an Article 4 direction.

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.

Is an over-garage extension right for your house?

  • Families needing a bedroom without losing garden
  • Detached and link-detached houses with an attached garage
  • Homes where the landing can connect to the new room

Fitting the new room to the existing landing is the planning puzzle inside the house. We design the connection first, then the roof, so the extension does not end up with awkward steps or a corridor through a bedroom.

Our process, step by step

Visits to Oban are arranged around travel; we confirm any travel costs in writing before the survey.

  1. Site visit by arrangement

    First, a site visit: we look at the house, garden, access and drains and listen to what you need.

  2. Design and approvals

    We draw the design, agree it with you and handle planning or permitted development checks and building regulations.

  3. Fixed written price

    You receive a written, itemised price and programme. Nothing starts until you are happy with it.

  4. Build and sign-off

    Our team builds the extension, keeps you updated weekly and finishes with building control sign-off.

Over-garage extension questions answered

Do I need building regulations approval in Oban?

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 Oban?

Yes. We cover Oban and the surrounding parts of Argyll and Bute. Projects here are taken on by arrangement because of travel, and any travel costs are agreed before the survey.

Will my neighbours in Oban be involved?

If a planning application is needed, the council notifies neighbours. Where work is close to a shared boundary, we agree access and protection with them in writing.

Can I keep using the garage during the build?

Usually not for parking. The garage roof is removed and the space below is used for access and props for part of the build.

Can my garage take the weight of a room on top?

Some can and some cannot. Many garages have a single-skin wall or shallow foundations. Our structural engineer checks this before we give a fixed price.
