Redesign Any Room With AI (for Under $2)
I redesigned my entire office with AI before buying a single piece of furniture. Every angle, every color option, real products I can actually order. Total cost was under two dollars.

I'm moving into a new house next month. The room I'm turning into my office is a kid's bedroom with a Spiderman poster on the closet door. Before I bought a single piece of furniture or touched a wall, I redesigned the whole thing with AI. Five photorealistic renders of my dream office in three minutes. For under two dollars. Not even exaggerating.. this is the closest thing to a personal interior designer I have ever used.
You do not need to hire a designer. You do not need to guess and hope you like it once it is built. You get to see every version of your room before you touch a wall or spend a dollar. Want to see it with a matte black feature wall? Done. Want warm walnut everywhere instead? Done. Different desk angle, different chair, different curtains? Done. In under a minute.
This costs real money to run but it is tiny. About 15 cents per render at high quality. Put ten bucks on your Google AI account and it lasts forever. No subscription. No monthly fee. You pay per image and that is it.
Here is the workflow once this is set up. You take photos of the room from every angle you care about. You tell Claude Code what you want it to look like, what should stay the same, and what to change. Claude Code hands the job to the image generator with your photos attached so the floors and windows stay exactly where they are. It gives you back photorealistic renders in about a minute. You look at them. You say "swap the desk for walnut, make the chair darker, add plants." It regenerates. You iterate until it is your dream room.
Here is how to get your API key from Google AI Studio:
- 1.Go to aistudio.google.com/apikey. Log in with any Google account. It is free to sign up.
- 2.Click "Create API key". It gives you a long string of letters and numbers. Copy it somewhere safe. Do not share it with anyone or paste it into a public chat.
- 3.Head to the billing page on the same site and put $10 on your account. That will last you hundreds of renders. You only get charged for what you actually use.
Install the nano-banana skill in Claude Code
Install the nano-banana skill from https://github.com/kingbootoshi/nano-banana-2-skill on my machine. I want to be able to run nano-banana from anywhere in my terminal.
Here is what I need you to do:
1. Clone the repo to ~/tools/nano-banana-2.
2. Run bun install, then bun link so the nano-banana command works globally. If bun is not installed, install it first.
3. Create the folder ~/.nano-banana/ and save a .env file inside it with my Gemini API key. My key is: [PASTE YOUR API KEY HERE]
4. Test it by running: nano-banana "a small matte black ceramic vase on a walnut desk, soft natural light"
5. Confirm the image saved successfully.
If anything breaks, walk me through the fix step by step. I am not a developer, so explain what each command does in plain English.That one prompt sets up the whole thing. Claude Code clones the repo, installs it, links it globally, saves your API key, and runs a test image so you know it is working. The whole setup takes about two minutes.
Redesign any room with AI
I want to redesign [WHICH ROOM, for example "my home office" or "my living room"] using AI image generation.
Here are photos of the room from every angle I care about:
[PASTE THE FILE PATHS TO YOUR PHOTOS, ONE PER LINE]
Here is what needs to stay exactly the same across every render:
- The floors
- All window positions and sizes
- All doors and closets (location, size, openings)
- The room dimensions and wall positions
Here is what I want to change:
- Wall color: [DESCRIBE THE COLOR, or say "give me a few options and pick what looks best"]
- Furniture: [DESCRIBE YOUR DREAM SETUP, for example "walnut standing desk, Herman Miller chair, matte black floating shelves with books and plants"]
- Ceiling light: [DESCRIBE, or say "something sculptural and modern"]
- Window treatment: [DESCRIBE, for example "floor-to-ceiling white linen sheers with a motorized blackout option"]
- Rug, decor, plants, art: [DESCRIBE, or say "make it premium, warm, and cohesive"]
For every photo I gave you, generate a photorealistic render of the redesigned room from that exact same camera angle. Use each photo as a reference with the -r flag so you preserve the floors, windows, and room proportions. Use the pro model at 2K resolution so the output is high quality. Save everything to ~/Desktop/room-renders/.
After you generate them, show me every render and tell me what it got right and what we might want to tweak on the next pass.That is the prompt. Paste it, fill in your specifics, and Claude Code does the rest. You get five renders of your dream room in under three minutes. For under two dollars. Every single time.
Pro tip. Be extremely specific about what should stay versus what should change. If you forget to say "keep the window exactly where it is", the AI will sometimes invent phantom windows or move doors around. The reference photos help a lot, but the more precise you are in words, the closer you get to buildable renders.
One thing that tripped me up on my own office redesign. The first batch of renders added windows that were not actually in the room. The fix is to tell Claude Code exactly how many windows and doors exist, and on which walls. It listens when you are specific.
Cost management matters here. Every render at 2K on the pro model is about 15 cents. Five angles twice is under two dollars. If you are still exploring styles and do not need final quality, drop to the Flash model at 1K for concept renders at five cents each. Use pro only when you are locked in.
Real product names render better than generic descriptions. "Herman Miller Embody in graphite" renders better than "an ergonomic chair". "Walnut standing desk" renders better than "a nice desk". The AI has seen the actual products, so use their real names whenever you can.
That is the whole thing. Get an API key. Install the skill in Claude Code. Take photos of your room. Paste the prompt above. Watch it generate the exact room you have been imagining in your head. Then iterate until it is right. No designer. No guessing. No wasted money on furniture you regret.
