AI-powered image and video tools are transforming the creative process for architects, product developers, and interior designers. In today’s competitive arena, speed, customization, and iterative workflows are the new gold standards¹. New multimodal models like Google’s Gemini (aka Nano Banana) let you prompt with text and images, enabling conversation-like design refinement. Top AI models (ChatGPT, Stable Diffusion 3, Google Imagen 3, etc.) are now accessible through user-friendly platforms (e.g. RenderAI), producing visuals in seconds that once took weeks¹. For example, designers can now rely on AI to accurately render furniture or spaces, and compose complex scenes on demand² — dramatically accelerating the entire workflow.

This guide explores a dual approach:

Getting Started with Google Studio (Nano Banana)

What is Nano Banana?

Nano Banana is Google’s latest AI image generation and editing model (Gemini 2.5 Flash Image), now part of Google AI Studio. It’s a multimodal model that natively understands text and images, allowing a seamless workflow for creating and editing visuals³. In practice, this means you can:

Prompt with text or images: Generate a new scene from a description, or upload a photo/sketch to edit with natural-language commands³.
Blend multiple inputs: Provide several photos to fuse into a new composition (e.g. place a product into an interior, or restyle a room with new textures)³ ⁴.
Maintain consistency: Keep the same character, object, or style across different prompts and images, perfect for branding or storyboarding⁴.
Refine by conversation: Engage in iterative, chat-like feedback. For example, you might say “blur the background” or “add hanging lights over the island,” and the model will apply each edit in sequence³ ⁴.

In essence, Nano Banana leverages Gemini’s deep world knowledge: it doesn’t just produce photorealistic scenes, but can interpret hand-drawn diagrams or follow multi-step instructions⁴. These advanced capabilities (often called visual reasoning) make it especially useful for architecture, product design, marketing mockups, or even educational illustrations.

Account Setup and Access

Sign Up / Log In: Visit Google AI Studio and sign in with your Google account.
Launch Nano Banana: Start with the “Gemini 2.5 Flash Image (Nano Banana)” module. (It’s included for both free-tier users and paying customers.)
Free Credits: New users typically receive trial credits to experiment with Nano Banana for free, making it easy to test out the AI rendering features.

Basic Workflow

Upload or Start Fresh: Begin with a sketch, a floor plan, or a blank scene. Nano Banana works with any visual prompt.
Prompt-Driven Editing: Describe what you want in natural language. E.g. “Convert this loft to a minimalist Nordic style with light oak floors” or “Ergonomic walnut lounge chair, Scandinavian design, soft lighting.”
Iterate & Refine: Use conversational commands to tweak the image. For example, “Change the rug color to navy,” “Add pendant lights above the table,” or “Remove the potted plant.” The model applies these edits step by step³.
Export: Once satisfied, download your high-quality render for presentations, portfolios, or further processing.

Key Gemini (Nano Banana) Capabilities

Multimodal Generation: Gemini’s Nano Banana handles text-to-image, image editing, and multi-image fusion all in one workflow³.
High-Fidelity Text Rendering: It can accurately render legible text within images, ideal for logos and posters³.
Visual Reasoning: The model understands complex visual instructions — like interpreting a floor plan or following multi-step design directions — beyond mere photorealism⁴.
Style/Character Consistency: Maintains the appearance of a character, object, or aesthetic across multiple images⁴.
Conversational Editing: Perform precise edits through simple language, like removing a background or recoloring an object⁴.

Real-World Examples

Architecture: “Contemporary glass facade, rooftop garden, sunset lighting.” Refine further with, “Add wooden slats on the balcony.”
Interior Design: Upload a room photo: “Convert this to a minimalist Japanese style with tatami mats.” Then refine with, “Make the cushions navy blue.”
Product Design: “Ergonomic lounge chair in walnut finish, Scandinavian style.” Then: “Add a throw pillow.”
Education/Marketing: Upload a sketch and ask, “Create a 3D render of this floor plan.” Nano Banana can interpret and generate.

3 Simple Steps with RenderAI

For those seeking a streamlined workflow optimized for professional design work, RenderAI simplifies the process into three essential steps:

Step 1: Upload Your Design Upload your architectural sketch, floor plan, or concept drawing directly to the app. RenderAI accepts various file formats and works with hand-drawn sketches, CAD screenshots, and others.

Upload your architectural sketch, floor plan, or concept drawing directly to the app

Step 2: Select Rendering Style and Create Magic Choose from RenderAI predefined rendering styles (Super-Fast, Fast-Definition, or Creative-Quality) based on your project needs, then click “Create Magic” to generate your AI-powered render.

Conclusion

By 2025, AI rendering has become integral to design workflows. It democratizes visualization: small studios and solo designers can now achieve what once required large render farms¹. This technological shift levels the playing field, allowing independent practitioners to compete with established firms through superior visualization capabilities.

Nano Banana excels in the ideation phase, offering rapid experimentation and creative exploration. Its strength lies in generating diverse concepts quickly, making it perfect for early-stage design development and client presentations. However, its limitations in image quality and features make it less suitable for final deliverables.

RenderAI represents the professional standard for AI rendering, engineered specifically for project-ready deliverables. Beyond core rendering capabilities, it offers a comprehensive suite of advanced features including online sketching tools, Image to Video conversion, and 8K upscaling technology. This integrated platform excels at handling complex architectural scenes while maintaining design integrity and producing consistent, high-quality outputs—making it the definitive solution for professional deliverables and client presentations.

The most effective workflow combines both tools strategically: professionals ideate with Nano Banana to explore basic possibilities, then transition to RenderAI for daily production. As AI rendering continues evolving, architects and designers who embrace these tools early will gain significant competitive advantages in an increasingly digital marketplace.
