Frequently asked questions

Which areas do you cover?

We’re based in the Highlands, but we’re available to carry out home extension projects all across Scotland.

What type of home extensions do you build?

All sorts! We specialise in a wide range of house extensions including:

  • Porches
  • Kitchen extensions
  • Conservatories
  • Side return extension
  • Single-storey and double-storey extensions
  • Dormer and loft extensions
  • Wrap-around extensions
Will I need planning permission for my home extension?

It depends on the type of extension. While planning permission isn’t always needed, you’ll need permission if your extension is over a specific size or height or if you live in a conservation area.

We’ll let you know if you need planning permission for your house extension project and who you need to contact.
