Best model: SDXL and Flux both render interiors and exteriors cleanly; Flux handles straight lines and glass especially well.
Architectural visualisation is specific: an architectural style (mid-century modern, brutalist, Scandinavian), the key materials (concrete, oak, brushed steel, travertine), the time of day and a named light direction, and a lens. Those four together produce a coherent space instead of a vague "nice room".
Interiors live on light and materials; exteriors add context (landscaping, sky, surroundings). Either way, a wide lens and a clear focal point keep the composition architectural rather than snapshot-like.

Tips that actually move the needle
- Name the architectural style ("mid-century modern", "brutalist", "Japandi") — it anchors everything else.
- List the key materials: concrete, oak, brushed steel, travertine. Materials are what make a space read as designed.
- Pick a time of day and light direction ("golden hour raking light", "overcast soft light", "dusk with interior glow").
- Use a wide lens (24–35mm) for spaciousness, and negative-prompt "fisheye distortion" to keep lines straight.
- Add "archviz quality" or "architectural photograph" to push toward clean, professional rendering.
Frequently asked questions
How do I get realistic interior lighting in AI renders?▾
Name both the time of day and the direction — e.g. "golden hour light raking across the room" or "soft overcast daylight". Add interior practical lights for dusk shots, and keep contrast realistic.
Why do my architecture renders look warped?▾
Very wide or fisheye framing distorts lines. Use a 24–35mm lens cue and negative-prompt "fisheye distortion, distorted perspective" to keep verticals straight.
