Créer des concepts d'architecture et de design d'intérieur bluffants avec des outils d'IA générative comme Midjourney et Stable Diffusion n'a rien de sorcier, même quand on débute.
Pour progresser vite, le plus efficace est d'étudier les prompts d'autres architectes et designers, de les adapter à vos besoins et de pratiquer beaucoup pour comprendre ce qui influence vos résultats.
Pour vous faire gagner du temps, nous avons rassemblé sur Internet quelques-uns des meilleurs prompts d'architecture pour Midjourney et Stable Diffusion, et nous les avons listés ci-dessous.
Ces prompts fonctionnent avec n'importe quel modèle text-to-image, mais aussi avec des outils de rendering IA spécialisés comme MyArchitectAI et des outils généralistes comme Nano Banana.
Vous trouverez également des bonnes pratiques et des conseils pour rédiger des prompts efficaces.
Midjourney comme Stable Diffusion sont de précieux alliés lors de la phase de conceptualisation d'un projet, mais pour en tirer le meilleur, il faut savoir où chacun excelle.
Voici la comparaison :
| Midjourney | Stable Diffusion | |
|---|---|---|
| Orientation | Rendus artistiques et stylisés | Rendus réalistes et techniquement détaillés |
| Syntaxe des prompts | Langage naturel avec modificateurs artistiques | Mots-clés et expressions mettant l'accent sur les détails |
| Modificateurs et paramètres | Style, format d'image, niveaux de qualité | Valeurs de seed, dimensions de l'image, steps |
| Modèles personnalisés | Non disponibles | Large choix de modèles personnalisés |
| Processus d'itération | Améliorations successives en ajustant le prompt | Génération directe avec des paramètres précis |
| Style de rendu | Concept art, mood boards et visualisation | Aperçus réalistes et rendus détaillés |
| Points forts | Créativité, visuels éclatants, styles singuliers | Exactitude, précision et représentation réaliste |
| Points faibles | Peut manquer de détails techniques et de réalisme | Peut exiger des prompts détaillés pour obtenir des variations de style |
| Meilleurs cas d'usage | Projets architecturaux conceptuels, représentations artistiques de projets, mood boards et storytelling visuel | Rendus architecturaux détaillés, aperçus réalistes pour les présentations client |

Savoir écrire des prompts pour Midjourney et Stable Diffusion est une compétence précieuse pour les architectes et les architectes d'intérieur. Mieux vaut s'y mettre dès maintenant pour ne pas se faire distancer.
Voici quelques excellentes formations en architecture et IA pour vous mettre à niveau.
Les prompts d'architecture listés ci-dessus sont une belle source d'inspiration pour créer vos propres designs et visualisations avec des outils d'IA générative.
L'expérimentation est très ludique, et nous sommes certains que vous y prendrez plaisir aussi !
Midjourney est l'un des modèles de génération d'images par IA les plus performants en architecture. Il excelle dans l'esthétique spatiale (où la plupart des autres modèles peinent), la composition, le réalisme des matériaux et des ombres, ainsi que les ambiances stylisées. C'est pourquoi les architectes l'apprécient pour la recherche de concepts. Pour les livrables client finaux qui exigent un réalisme de niveau production, la plupart des studios l'associent à des outils de rendu architectural dédiés.
Plus ou moins. Il produit une image de plan qui paraît convaincante au premier coup d'œil, mais il ne respecte pas vos spécifications, donc le résultat n'est guère exploitable.
Midjourney est bien plus avancé que le générateur d'images de ChatGPT (GPT-Image 1). Il offre un réalisme plus poussé et des résultats plus cohérents (notamment pour les visages, les mains, etc.). Il donne aussi plus de contrôle artistique grâce à des réglages comme les negative prompts (paramètre --no), la pondération des prompts (syntaxe ::) et la prise en charge du transfert de style.
La résolution par défaut est de 1024 px, ce qui convient aux réseaux sociaux mais reste insuffisant pour l'impression ou les grands écrans. Même les upscalers Subtle et Creative intégrés plafonnent à 2048x2048 : il n'existe pas de 4K native, quel que soit l'abonnement, et l'upscaling dans Midjourney consomme votre temps GPU. Si vous avez besoin d'une résolution supérieure à 1K, le mieux est de passer le résultat dans un upscaler Midjourney tiers pour qu'il soit prêt à imprimer.
