What should an exterior architecture prompt include?+
The cladding system, window frame colour, roof treatment, immediate landscaping and a specific light condition. Those five together carry most of the realism. Because the AI preserves your uploaded geometry, you do not need to describe the building form itself.
Overcast or sunny — which renders better?+
Overcast light flatters materials and is more forgiving, which is why it dominates real architectural photography. Direct sun creates drama and strong shadows but exposes weak geometry. Choose deliberately rather than leaving it unstated.
How do I keep the facade design unchanged?+
Upload the view and describe only surfaces, light and context. Architectural AI locks the footprint, openings and roof form from your image — the prompt controls what those surfaces are made of, not where they are.
Can I test several cladding options quickly?+
Yes, and this is the highest-value use. Run the same view with three different cladding sentences to compare timber, brick and render side by side before specifying.
