Free AI Window Designer

Windows shape the daylight and the elevation of every room. The AI Window Designer previews new frame styles, glazing patterns, and window shapes on a photo of your existing openings.

It replaces sashes, frames, mullions, and glazing bars while keeping the opening size and the wall around it intact. You can preview steel, timber, or aluminium in various colours.

• Homeowners replacing tired uPVC windows
