This is a submission for the Google AI Studio Multimodal Challenge
What I Built
I built ArchitechDream, a web application designed to bring architectural visions to life.
At its core, ArchitechDream is an AI-powered conceptual design partner. It addresses the challenge many face when trying to visualize a home or building: turning a fleeting idea into a tangible, visual concept.
Whether you're an aspiring homeowner, an architecture student, or just a creative mind, this applet empowers you to:
- Instantly Generate Concepts: Simply describe your dream home, and
ArchitechDreamgenerates ten distinct, photorealistic architectural designs. - Explore Variations: See your idea from multiple angles, in different styles, and with unique creative flairs, all from a single prompt.
- Iterate and Refine: Use the powerful multimodal editor to tweak designs conversationally. Want to add a pool, change the materials, or see it at sunset? Just tell the AI.
ArchitechDream aims to democratize the initial phase of architectural design, making it more accessible, interactive, and inspiring for everyone.

Here’s a quick look at how it works:
The main interface, featuring an intuitive prompt box and inspiring suggestions.
A gallery of generated architectural concepts based on a single prompt.
The powerful editing modal, where users can refine their designs with text.
How I Used Google AI Studio
ArchitechDream is built entirely on the power and flexibility of the Google Gemini API, orchestrating multiple models to create a seamless, multimodal design experience.
I strategically integrated three distinct models, each excelling at its specific task:
Image Generation with *Imagen 4.0 (
imagen-4.0-generate-001)*: This state-of-the-art model is the creative engine for initial concepts. To provide a rich palette of options, the app makes parallel API calls to efficiently generate a batch of 10 high-resolution, photorealistic images (16:9aspect ratio) from a single user prompt. This ensures variety and speed, which are critical for a great user experience.Contextual Description with *Gemini 2.5 Flash (
gemini-2.5-flash)*: To add depth and narrative to the visuals, Gemini 2.5 Flash analyzes each generated image. It functions as an AI art critic, providing a short, elegant architectural description for every concept. This image-to-text capability transforms a simple gallery into a portfolio of ideas.Multimodal Editing with *Gemini 2.5 Flash Image Preview (
gemini-2.5-flash-image-preview): This is the core of the app's interactive magic. Leveraging this powerful multimodal model (also known as *Nano Banana), users can conversationally refine their chosen design.
The model takes the existing image and a new text prompt as input, generating a new, edited image and an updated description in a single API call. This creates a fluid, iterative feedback loop that feels like collaborating with a human designer.
Multimodal Features
The user experience in ArchitechDream is fundamentally multimodal, creating a seamless and conversational design process.
Text-to-Image Generation & Image-to-Text Description: The initial step is a classic multimodal pipeline. The user provides text, and the app returns a set of images. Immediately after, the app takes each image and generates descriptive text. This provides users with not just visuals, but also a narrative for each design.
-
Conversational Image Editing (Image + Text → New Image + New Text): This is the app's standout feature. When a user wants to edit a design, they aren't starting from scratch. Instead, they engage in a multimodal dialogue with the AI.
- Input: The user provides the current image and a new text prompt (e.g., "change the siding to dark wood and add a garden").
- Output: The AI returns a newly generated image that reflects the changes and a new text description to match.
This iterative loop is incredibly powerful. It mimics a natural conversation with a human designer, allowing for nuanced changes and creative exploration that would be impossible with text prompts alone.
It truly enhances the experience by making the design process fluid, intuitive, and deeply personal.
