AI Sketch to Image in 5 Steps: Ever wondered how to turn your basic architectural sketches into professional-grade renderings without expensive software or years of training? AI architecture tools have revolutionized how designers approach sketch to image transformation, making photorealistic visualizations accessible to everyone.
This workflow combines SketchUp for 3D foundation, ChatGPT for prompt optimization, Prome AI for sketch to image ai generation, and Leonardo AI for professional upscaling. You'll create stunning architectural visualizations in a fraction of traditional rendering time, perfect for presentations, client pitches, or design exploration.

Best AI Tools for Architectural Visualization
Quick links to the top AI architecture tools mentioned in this guide.
Create your architecture sketch or design
- Create your initial design using hand sketching or digital tools like SketchUp (free, web-based platform, the one I used)
- Focus on basic shapes - this foundation will guide your ai sketch generator
- Screenshot/Take a photo of your sketch
- Pro tip: Simple, clear foundational forms work better than complex details at this stage
Find a Style Reference
- Find a style reference image (I use Pinterest) that shows your desired architectural and artistic style
- Save the image for uploading alongside your sketch - this will help the sketch to image AI understand your vision
- Consider environmental elements: time of day, weather, surrounding landscape for more accurate results
Optimize Your Prompts with AI
- Describe what you want your AI sketch to image generation look like in your own words to ChatGPT
- Upload both your sketch and style reference image for complete context
- Ask for architectural aspects: materials (glass, steel, concrete), lighting conditions, and camera angles
- Let ChatGPT generate optimized prompt
Generate Architectural Renderings
- Go to Prome AI (free tier available) and upload your sketch and style reference image
- Paste your optimized prompt
- Select additional settings: style/scene/structure
- Note: Free tier provides preview-quality downloads that we'll enhance in the next step
Upscale Image
- Navigate to the Upscale feature in Leonardo AI
- Upload your generated image
- Process the upscaling - this transforms preview-quality images into high-quality renderings
- Download your professional result - Leonardo AI provides 5 free daily upscales for users
