Visualizing design ideas has become essential for architects. Advanced tools like MidJourney offer the ability to turn text descriptions into stunning visuals. However, the quality of these generated images heavily relies on the precision and clarity of the prompts used.
In this scenario, ChatGPT can be a powerful tool to help create detailed and well-structured prompts, guiding MidJourney in producing high-quality architectural visualizations. This article will explore how to craft effective prompts for image generation through ChatGPT, with a focus on practical applications for architects and architectural firms.
Understanding the structure of an effective prompt
An image generation prompt needs to provide clear and specific guidance on various aspects of the scene you want to create. A well-structured prompt will direct the AI to produce an image that faithfully reflects the design intent.
Key Elements of a Prompt:
Theme or purpose:
Describe the overall theme or goal of the image. For example, “A modern façade for a commercial building in an urban setting.”
Architectural style:
Specify the desired architectural style, such as “minimalist,” “brutalist,” or “neoclassical.”
Materials and textures:
Indicate the main materials and textures, like “exposed concrete” or “glass and steel façade.”
Lighting and environment:
Describe the lighting conditions and the environment, such as “sunset lighting” or “a nighttime urban landscape.”
Specific details:
Include additional details that might influence the composition, such as “people walking in the square in front” or “vertical greenery on the external walls.”
Using ChatGPT to create detailed prompts
As previously said, ChatGPT can be used to generate more elaborate and complex prompts, making the most of MidJourney’s capabilities. Always remember that for ChatGPT contextualization is very important, so before asking him to help you generate prompts from your inputs, always remember to specify how and why you are asking. Insert a sentence like this at the beginning of each of your conversations of this type for example “could you help me generate a prompt that can be used on Midjourney or other similar platforms? Start from my sentence and try to translate it into an effective prompt that adheres to it.”
Here are some steps to get the best results:
Simple and iterative inputs:
Start with a simple input and then refine the details through successive iterations. For example:
First prompt: “Describe a modern residential building in a city”Second prompt (more detailed): “Describe a 10-story modern residential building with a glass and steel façade, located in a coastal city, illuminated by sunset light, with people walking along the seafront”Add more details to clarify the project’s vision:
Specify what materials you’d like to use for the building’s façade, for instance. Or what kind of atmosphere you want the image to convey. Or if there are specific elements you want to include, like vegetation or other architectural details.
Or you can use ChatGPT to experiment with styles or details:
ChatGPT can help you explore different visual styles. You might ask:
“Generate a prompt for an Art Deco building with gold details.”“Describe a futuristic skyscraper with organic shapes and curved lines.”Alternatively, or additionally, you can include environmental details like “weather conditions” or “time of day” can enhance the image’s atmosphere.
For example, “A public square at dawn, with fog enveloping the buildings’ outlines and a few passersby crossing the scene.”Some examples of MidJourney detailed prompts
Here are some example prompts you can create using ChatGPT to obtain high-quality architectural images with MidJourney:
Prompt for a Modern Residential Building:
Prompt for a Contemporary Public Park:
Prompt for a Modern Art Museum:
Refining and optimizing prompts for MidJourney
Once the prompts are generated with ChatGPT, it’s useful to optimize them for MidJourney, considering the platform’s specific features.
MidJourney supports various commands that can be included in prompts to further refine the image, you can see all of them by visiting this post, a dedicated short and simple guide.
In any case, don’t hesitate to run multiple iterations of the prompt and experiment with various details. Even small changes can significantly impact the final result.

ChatGPT and MidJourney represent a powerful combination for generating architectural images that can significantly improve the design and communication process. Creating effective prompts requires a clear understanding of the design needs and the ability to articulate these needs in a detailed and precise manner. With a structured and iterative approach, it’s possible to produce images that not only reflect the project’s vision but even elevate it, contributing to the overall success of the architectural firm.
