How It Works
No CAD software. No architect needed yet. Just a photo of your house and a clear idea of what you want.
Take a clear exterior photo of your house — front or rear, whichever shows the wall where you want the extension. JPG or PNG up to 10MB. Daylight works best; straight-on or up to 45° angle.
Choose from 5 extension types and 3 finish styles. Then set your exact dimensions — house width, extension width, how far it extends into the garden, and wall height. A live floor plan updates as you type.
Our AI generates 3 photorealistic extension renders in about 90 seconds. Preview all 3 with watermarks for free. When you're happy, pay €9.99 to unlock the full 2048px files with no watermarks.
ExtensionVision uses a combination of image segmentation (SAM2) and photorealistic inpainting (FLUX Fill Pro) to detect your house structure, mask the extension area, and generate architecturally plausible renders in your chosen style — scaled to your entered dimensions.
