These are the 35 Claude prompts for interior design we actually use, grouped by the job they do and tested on real rooms. Copy one, swap the bracketed parts, paste it into Claude. If you would rather skip the typing and just describe a room, the MeltFlex AI prompt tool turns the same kind of request into a render of your real space. The prompts come first. The how, the why, and the tool comparison are right after.
Room Analysis Prompts (1 to 8)
Upload your room photo first. Claude reads images, so it can spot undertone clashes, bad proportions, and missing layers that you feel but cannot name. Every prompt below assumes you attach a photo.
1. The Complete Room Audit
"[Upload room photo] Audit this room. Tell me: (1) the current design style, (2) the color palette with hex codes, (3) what is working, (4) what is not working, (5) the 3 highest impact changes I can make for under $[budget]. Name specific products, paint codes, and exact placement. Explain your reasoning for each."
2. The Proportion Check
"[Upload room photo] Review the furniture proportions. Is anything too big, too small, or badly placed? Rate each piece 1 to 5 for how well it fits the room. For anything below 4, give me the correct size range in inches."
3. The Lighting Plan
"[Upload room photo] Analyze the lighting. Where are the dark zones? Is the light warm or cool? Give me a three layer lighting plan (ambient, task, accent) with fixture types, placement, and bulb color temperature in Kelvin. Budget: $[X]."
4. The Style Identifier
"[Upload room photo] What interior design style is this room? Give me percentages, like 70% Scandinavian and 30% Industrial. Then list 5 specific pieces I could add to make the style feel intentional instead of accidental, and tell me what to search for online."
5. The What Feels Off Diagnosis
"[Upload room photo] This room feels off to me but I cannot explain why. Diagnose it. Look at balance, scale, color temperature, negative space, and focal point. Give me the single biggest problem first, then the next two."
6. The Empty Room Plan
"[Upload photo of empty room] This room is empty. It is [dimensions] and faces [direction]. I want a [style] look for [who uses it] on a $[budget] budget. Give me a full furnishing plan: layout, every piece with size, color palette, and the order I should buy things in."
An empty room is the cleanest test of a plan. Here is one furnished straight from a single photo, with the walls, windows, and floor left exactly as they were.
7. The Keep or Replace Sort
"[Upload room photo] Sort everything in this room into keep, repurpose, or replace. For keep, tell me how to style it better. For replace, tell me what to buy and roughly what it costs. I want to spend as little as possible."
8. The Rental Friendly Review
"[Upload room photo] I rent and cannot paint, drill, or change flooring. Give me the 5 highest impact upgrades I can make that are fully reversible. Include peel and stick options, freestanding pieces, and lighting. Budget: $[X]."
Once Claude has told you what to change, the fastest way to check it is real is to drop the same photo into MeltFlex and apply the look to your actual room.
Color, Palette and Material Prompts (9 to 16)
This is where Claude pulls ahead. Color is really just reasoning about light and undertone, and reasoning is the thing Claude does best. Ask for hex codes and real paint names so the answer is something you can act on, not just admire. The same kind of palette prompt can go quiet or bold: a calm sage bedroom, or a deep forest green living room with warm brass light. Both were planned by Claude and rendered in a real space.
9. The Full Palette Builder
"Build me a 5 color palette for a [room] in a [style] style. Give each color a role (wall, large furniture, textile, accent, metal), a hex code, and a real paint name from Benjamin Moore or Farrow and Ball. Tell me the rough ratio to use each one."
10. The Undertone Match
"[Upload photo] My [floor / sofa / countertop] is [color]. Tell me its undertone, then give me 4 wall colors that work with it and 2 that will clash and why. Include hex codes and paint names."
11. The 60 30 10 Breakdown
"Apply the 60 30 10 rule to my [room]. My fixed elements are [list them]. Tell me exactly which color is the 60%, the 30%, and the 10%, with hex codes, and where each one goes in the room."
12. The One Color Story
"I love the color [color]. Build an entire room around it without it feeling like too much. Give me the supporting palette, where the main color appears, and 5 specific products that carry it. Style: [style]."
13. The Material Mix
"Give me a material and texture plan for a [style] [room]. Cover wood tone, metal finish, stone or tile, and at least 3 textiles. Tell me how to mix them without clashing, and name the one rule people break most."
14. The Wood Tone Fix
"My room has [wood floor tone] floors and I want to add [wood furniture tone] furniture. Will they fight? Give me the rule for mixing wood tones, and tell me what to add (a rug, a metal, a textile) to make the mix look deliberate."
15. The Mood to Palette Translator
"I want my [room] to feel [calm / energizing / cozy / luxurious]. Translate that feeling into a concrete palette with hex codes, a lighting temperature, and 3 materials that reinforce the mood."
16. The Trend Check
"Is [trend or color] going to look dated in two years, or is it a safe long term choice? Give me an honest answer, then tell me how to get the look in a low commitment way in case I change my mind."
Furniture and Layout Prompts (17 to 24)
Give Claude numbers and it reasons about space surprisingly well. Tell it the room dimensions and where the doors, windows, and outlets are, and it will place furniture that actually leaves room to walk. Same room, this time in a bright Scandinavian direction.
17. The Layout From Scratch
"My [room] is [length] by [width]. Doors are at [location], windows at [location], the TV or focal point is at [location]. Design the furniture layout. Give me placement, walking paths, and the size each piece should be. Explain the traffic flow."
18. The Rug Size Calculator
"My [room] is [dimensions] and my [sofa or bed] is [size]. What rug size do I need, and how should the furniture sit on it? Give me the exact dimensions to search for and the rule you used."
19. The Small Space Maximizer
"My [room] is only [dimensions]. Make it feel bigger and work harder. Give me layout, multifunctional pieces, the visual tricks that actually help, and the mistakes that make small rooms feel smaller."
20. The Awkward Room Solver
"[Upload photo] My room is awkward: [L shaped / long and narrow / sloped ceiling / too many doors]. Give me a layout that works with the shape instead of fighting it. Tell me where the seating, storage, and focal point go."
21. The Open Plan Divider
"I have one open space that needs to be [living plus dining plus work]. Show me how to zone it without walls. Cover furniture placement, rugs, lighting, and sight lines so each zone feels separate but connected."
22. The Exact Shopping Spec
"Turn this layout into a buy list. For every piece give me the category, the exact dimensions to search for, a target price, and 2 search terms I can paste into Amazon or IKEA. Sort by what I should buy first."
23. The One Sofa, Many Options
"Help me choose a sofa for a [dimensions] room in a [style] style, budget $[X]. Tell me the right size and shape, the best fabric for [pets / kids / low maintenance], the colors that work, and what to avoid."
24. The Storage Plan
"[Upload photo] This room has no storage and looks cluttered. Give me a storage plan that looks intentional, not like organizing bins. Cover hidden storage, vertical space, and furniture that doubles as storage. Budget: $[X]."
Before you buy any of it, paste the layout into MeltFlex and see the pieces in your actual room. A sofa that sounds right in a Claude plan can still be the wrong scale once you see it on your wall.
Budget and Shopping List Prompts (25 to 30)
Claude is unusually good at honest budgeting because it reasons through tradeoffs instead of just listing products. Be specific about your number, and it will tell you where a few hundred dollars actually shows and where it does not. A warm dining nook like the one below does not need a big budget, it needs the right three or four pieces.
25. The Budget Allocator
"I have $[total] to furnish a [room] from scratch. Allocate it across every category as percentages and dollar amounts. Tell me where to spend more, where to save, and the one piece worth blowing the budget on."
26. The Splurge vs Save List
"For a [style] [room], tell me which 3 pieces are worth splurging on and which 5 I should buy cheap. Explain why for each, based on how much it gets used and how much quality shows."
27. The Phased Plan
"I cannot buy everything at once. Break my [room] makeover into 3 phases over [timeframe], each under $[amount]. Order them so the room looks intentional at the end of every phase, not half finished."
28. The Dupe Finder
"I love [expensive piece or designer look] but it costs $[X]. Tell me what makes it look expensive, then how to get 90% of the look for a fraction of the price. Give me search terms and target prices."
29. The Cost To Furnish Estimate
"Estimate the realistic cost to furnish a [room] in a [style] style at three levels: budget, mid range, and high end. Break it down by piece so I know what drives the number."
30. The Hidden Cost Check
"I am planning to [furnish a room / redo a kitchen / move in]. What costs am I forgetting? List the hidden ones people miss (delivery, assembly, window coverings, lighting, small stuff) with rough amounts."
Renovation and Project Planning Prompts (31 to 35)
For anything bigger than decorating, Claude holds a long plan together better than any other AI. Give it the full picture and let it think. It is just as comfortable keeping a whole home cohesive, like the Japandi and mid-century takes below, as it is planning a single room.
31. The Renovation Brief
"I want to renovate my [room]. Goals: [list]. Budget: $[X]. Timeline: [X]. Write me a full brief I could hand to a contractor: scope, must haves, nice to haves, the order work should happen in, and the decisions I need to make before they start."
32. The Design Brief For Pros
"Turn my ideas into a clear design brief. My style: [style]. Rooms: [list]. Likes: [list]. Hard nos: [list]. Budget: $[X]. Write it the way a designer expects to receive it, so I sound like I know what I want."
33. The Decision Maker
"I am stuck between [option A] and [option B] for my [room]. Lay out the tradeoffs honestly: cost, durability, how dated each will look, and which fits my [style] better. Then make a recommendation and tell me your confidence."
34. The Whole Home Cohesion Plan
"I want my whole home to feel cohesive without being matchy. Give me a through line (palette, materials, or a repeated detail) that ties [list rooms] together while letting each room have its own character."
35. The Image Prompt Writer
"Write me a detailed image generation prompt for my dream [room]. Style: [style]. Must include: [elements]. Make it specific about materials, lighting, camera angle, and mood, so I can paste it into an image tool."
Prompt 35 is the bridge. Claude writes the perfect description, but it cannot render it. Paste that prompt into MeltFlex to see it in your real room, or into Gemini or Nano Banana for a concept image. If you want the prompts done for you, the MeltFlex prompt tool has ready-made ones you can run on your own photo.

Why Claude for Interior Design
Most interior design mistakes are expensive because they happen after you have already bought the sofa. Claude is the best AI writer and reasoner of the big three, which makes it the right tool to think the room through before you spend a cent. Hand it a photo and it reads the space, plans the whole thing, sizes the furniture, and writes the shopping list. Every prompt above was tested on a real room.
One honest note: Claude does not draw pictures. It plans, it does not render. So the workflow is simple. Think it through with Claude, then see it in your real room with MeltFlex, which keeps your actual walls, windows, and floor while the furniture and style change around them.
Connect Claude Directly to MeltFlex
You do not have to copy prompts between tools. MeltFlex ships an MCP server, which lets Claude and Claude Code call MeltFlex directly. You describe the room to Claude in plain language, Claude calls MeltFlex, and a room accurate render comes back in the chat. You get Claude’s planning and writing plus real visualization in one place.
If you use Claude Code, the same setup works for architects and designers who want to generate renders from the terminal. See the Claude Code MCP guide for the full walkthrough.
What Claude Cannot Do (Read This)
Claude is a text model. It will not generate an image of your redesigned room, it cannot pull live prices the way Gemini can, and it cannot see your room in 3D. Where it beats every other AI is thinking: honest budgets, layouts that account for traffic flow, palettes with real reasoning, and plans that stay consistent across a whole project.
So the workflow that actually works is simple. Plan with Claude. See it in your real room with MeltFlex. Buy once, with confidence, instead of guessing.
Try It Free Right Now
Take any plan Claude gives you and see it in your actual room in under a minute. MeltFlex has a free tier: upload a photo, describe the look, and watch your real walls, windows, and floor stay exactly where they are while the furniture and style change around them.
