Frequently Asked Questions
Is the AI extension visualiser free?
Yes, completely free. There is no charge, no sign-up required and no obligation. You can generate a visualisation and refine it up to five times at no cost.
What photo do I need?
A clear, well-lit photo of the side of your house where the extension will go. Landscape orientation, taken in daylight, standing far enough back to capture the full wall. Phone camera photos work perfectly.
How accurate are the images?
The AI generates concept visualisations showing realistic proportions, style and scale. They are designed to help you plan and communicate your ideas — not as architectural drawings or planning documents.
Can I refine the image?
Yes. After your initial result, you can request up to five refinements — adding a skylight, changing the roof type, adjusting size or switching materials.
How long does it take?
The AI typically generates your visualisation in one to two minutes. Refinements take a similar amount of time.
