Dundee over-garage extensions, designed and built

A over-garage extension in Dundee starts with the right design and the right approval route. We take care of both, then build it with our own project management.

Planning rules that apply in Dundee

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. Separately, almost every extension needs a building warrant from the council before work starts.

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

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 an over-garage extension makes sense

  • Detached and link-detached houses with an attached garage
  • Families needing a bedroom without losing garden
  • 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.

From first visit to completion

Site visits are free and there is no obligation. Where drawings are needed, the design stage is priced in writing before it starts.

  1. Free site visit

    A designer visits, takes measurements and photos, and discusses layouts, budget and timing with you.

  2. Design and approvals

    We produce the drawings and structural design, and manage the approvals so they are in place before work starts.

  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

Can I see a price before committing to anything?

Yes. The guide prices on this page are adjusted for Dundee, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.

Who do I contract with for an over-garage extension in Dundee?

Your contract is with S&K Property Investments and Improvement Ltd, which designs and manages the project and the build teams who carry it out.

Do you cover all of Dundee?

Yes. We cover Dundee and the surrounding parts of Angus and Dundee. Site visits are free and there is no obligation.

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.

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.
