How much does a house extension cost?

The cost of a house extension will be influenced by many factors. Therefore, we recommend contacting us for a FREE quote.

Do I need planning permission for a home extension?

As most extensions fall under Permitted Development you shouldn’t need planning permission. This refers to the rights given to you as a homeowner to make renovations to your home without having to get permission first. Contact us for more information if you’re unsure.

We also do outbuilds…

In addition to offering a complete package for extensions, we also design, build and install stylish outbuildings. Outbuilds are detached buildings often at the end of a garden that can be transformed into gyms, offices, pubs and more. Contact us for more information and a FREE site visit!
