What works best for Dundee houses?
Across Scotland, extensions follow Scottish planning and building standards, including the building warrant process, which we build into the programme from the start.
For many houses here, bungalow extensions, single-storey rear extensions or orangery extensions gives the most useful space for the budget.
Dundee and surrounding towns
Site visits are available across Dundee (DD1, DD2, DD3, DD4, DD5). The same team covers Forfar (13 miles), Arbroath (16 miles), Montrose (28 miles), all within easy reach. For homes towards Fife, St Andrews is around 11 miles away.

Approvals for an extension 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.
In a conservation area or national scenic area the householder permitted development rights are more limited, listed homes need listed building consent, and if rights have been removed by a condition or direction, any extension needs an application.
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.
Applications are decided by your council as planning authority.

Free site visit
A designer visits, takes measurements and photos, and discusses layouts, budget and timing with you.
Design and approvals
Once the layout is agreed, we deal with the council: planning permission or written confirmation that none is needed, plus building control.
Fixed written price
The price is fixed in writing once the design is settled, with a clear programme and payment stages.
Build and sign-off
We build it with one project manager, book the building control inspections and hand over the completion certificate.

Will my neighbours need to be told?
If you apply for planning permission the council notifies neighbours, and we agree access with them in writing for work near a shared boundary.
