House Extensions in Edinburgh

Yes. Every extension we build is covered by our own workmanship guarantee, so if anything tied to how we have carried out the work goes wrong, we come back and put it right. The structure, foundations, and weatherproofing are all built to comply with Scottish Building Standards, and the work is inspected and signed off through the building warrant process. Before we hand the extension over, we walk you through the finished build room by room to check the finish and make sure you are happy with every detail.

The materials we fit come with the warranties offered by the firms that make them, and those run separately from our own guarantee on the labour. Structural steel, ready-mix concrete, and high-performance insulation are all sourced from established suppliers and installed strictly to their specifications, which is what keeps those manufacturer warranties valid. We keep the paperwork and pass the relevant details on to you once the build is complete.

Not every extension needs planning permission, but some do depending on the size, position, and type of property. We can advise on what is likely to need approval before the job moves forward.

In most cases, yes. House extensions in Scotland usually require a building warrant, and we prepare the Local Authority Building Standards submission on your behalf. The work is inspected at the key stages and must meet current building standards before a Certificate of Completion is issued and the job is signed off.

The timescale depends on the size of the extension, the complexity of the structure, site access, and the level of internal finish. A straightforward single storey build will usually move much faster than a large two storey extension with structural changes to the existing house.

Yes. Matching the new work to the original house is a big part of getting the job right, so we pay close attention to materials, rooflines, openings, and finishing details.

In many cases, yes, especially during the early stages. If the build involves major internal openings or temporary loss of kitchen space, we will explain that upfront so you know what to expect.

The main factors are size, ground conditions, structure, access, materials, glazing, and internal fit-out, along with how much work is needed to alter the existing house. Because of those variables, the cost per square metre changes from one job to the next, so a clear site visit is the best way to price the job properly rather than relying on a generic Scotland-wide rate.

If the extension design requires a steel beam (RSJ) to form a knock-through, or other structural supports, that is planned in before the build starts and installed as part of the main construction phase. A structural engineer prepares the beam calculations first, so the loads are properly worked out, and propping stays in place until the new beam is fully supported and the work is carried out in the right order.
