Point it at a photo of a room, describe the look you want, and Nano Banana (Google's gemini-2.5-flash-image model) returns a redesigned version -- new furniture, new palette, new mood -- in seconds. No Pinterest boards, no Figma, no standalone room-planner app. Interior design is one of the highest-value things Nano Banana does, and it's the use case people search for most: banana skill claude interior design, claude design nano banana, nano banana room redesign. This guide covers exactly how to do it -- the setup, the prompts that actually work, and where the model still needs a human. If you haven't installed the skill yet, start with our Nano Banana skill setup guide and come back -- it's a 10-minute, one-time install. Why Nano Banana Is Good at Interior Design Most AI image generators invent a room from scratch. That's useless for design work -- you want your room, redesigned, with the walls and windows in the same place. Nano Banana's /edit command is different. It takes an existing photo as input and modifies it while preserving the underlying geometry. That's the whole game for interior design: Keeps the room's structure -- window positions, ceiling height, door placement stay put Swaps style, not layout -- you change the furniture, palette, and materials, not the bones Iterates cheaply -- at ~$0.04 an image, you can try ten directions for 40 cents Runs where you already work -- inside Claude, same session, no context switch That combination -- real photo in, restyled photo out, for pennies -- is why "banana skill claude interior design" became a search in the first place. Setup: Connect Nano Banana to Claude If the skill is already installed, skip this. If not, here's the short version (full detail in the setup guide): # 1. Install the Gemini CLI npm install -g @google/gemini-cli # 2. Export your Gemini API key (get one at aistudio.google.com) export GEMINI_API_KEY="your-key-here" # 3. Install the nanobanana extension gemini extensions install https://github.com/gemini-cli-extensions/nanobanana # 4. Install the skill into Claude Code git clone https://github.com/kkoppenhaver/cc-nano-banana ~/.claude/skills/nano-banana Restart Claude Code. Now any image request routes through Nano Banana automatically -- including "redesign this room." How to Redesign a Room with Claude Nano Banana The workflow is: take a photo -> hand it to Claude -> describe the target style -> review -> refine. 1. Start with a real photo Take a straight-on photo of the room in decent light. Wide angle, minimal clutter, whole space in frame. Save it into your working directory (e.g. living-room.jpg). 2. Ask Claude to redesign it Redesign this living room in a warm Scandinavian style. Light oak floors, a cream boucle sofa, black metal accents, lots of plants, soft natural light. Keep the window and layout exactly as they are. Photorealistic. Claude routes it to: gemini --yolo "/edit living-room.jpg 'redesign in warm Scandinavian style: light oak floors, cream boucle sofa, black metal accents, plants, soft natural light, keep window and layout unchanged, photorealistic'" The restyled image lands in ./nanobanana-output/. Open it, and if the direction is right but a detail is off, edit again. 3. Refine in plain English Same room, but make the sofa charcoal grey instead of cream and add a large abstract painting above it. Each refinement is another /edit on the previous output. This is where Nano Banana beats a mood board -- you're iterating on your room, not collecting other people's. Prompts That Work for Interior Design The difference between a mediocre redesign and a great one is almost entirely in the prompt. Patterns that hold up: Name the style explicitly -- "mid-century modern," "Japandi," "industrial loft," "coastal," "warm minimalist." Vague prompts produce muddy results. Specify materials -- "walnut," "brushed brass," "linen," "terrazzo," "matte black." Materials do more for realism than adjectives. Lock the layout -- always add "keep the window, door, and layout unchanged." Otherwise the model drifts the geometry. Set the light -- "soft morning light," "warm evening lamps," "bright natural daylight." Lighting sets the entire mood. Ask for photorealism -- add "photorealistic, interior photography" unless you want an illustration. Generate variations -- add --count=3 to get three directions in one call and pick the strongest. Use case: staging an empty room Stage this empty bedroom for a real estate listing. Neutral modern furniture, queen bed, warm lighting, tasteful decor. Photorealistic. Keep the room's dimensions and windows unchanged. Virtual staging normally costs $25-75 per photo through a service. This is one command. Use case: testing a palette before you buy paint Show this room with the walls painted deep sage green instead of white. Everything else identical. Use case: before/after concepts for clients Generate the "before" (the raw photo) and three "after" directions, drop them side by side, and let a client pick a direction before anyone spends money. What It Doesn't Replace Nano Banana is a concepting tool, not a construction document. It won't give you accurate dimensions, a furniture shopping list with real SKUs, or load-bearing-wall advice. Occasionally it will hallucinate a piece of furniture that doesn't exist or bend a straight line. What it replaces is the slow, expensive front of the process: the mood-boarding, the "what would this room look like in a different style" question, the virtual staging bill. For exploring directions fast and cheap -- before committing real money to paint, furniture, or a designer -- it's hard to beat. For a finished, buildable design with real products and measurements, you still want a human designer. Use Nano Banana to walk into that conversation already knowing what you want. Get Started Install the skill (see the setup guide) Photograph the room, straight on, good light Ask Claude: "Redesign this room in [style], keep the layout, photorealistic" Refine with plain-English edits until it's right Add --count=3 when you want to compare directions The first redesign takes seconds and costs about four cents. That's the whole pitch: interior design concepts, from a real photo, without leaving the tool you're already in. Want AI Wired Into Your Workflow?
