AI room redesign prompts: what to keep and what to change

“Make it warm and modern” gives an AI room redesign a direction. It leaves some of the important decisions open: whether your sofa stays, whether the flooring changes, and which details made you like the room in the first place.

Before generating a new version, write a brief in three parts: keep, change and avoid. It gives you something specific to ask for and a clear way to judge the result.

Start with the room you actually have

Choose a photo that shows the area you want to restyle. A clear, well-lit image with the camera reasonably level makes it easier to describe the visible furniture and fixed features. If the image leaves out a wall or doorway, do not assume the resulting picture tells you what happens there.

In Renovaitor's Studio, you can choose a room photo or start with one of the built-in samples. The current entry screen includes living-room, bedroom, empty-room and exterior samples. If you select a sample while signed out, you will be asked to sign in before continuing.

You can choose a style direction or use your written brief. The screen shows a generation-credit estimate; choosing an image or writing the brief does not itself start a paid render. AI tools use credits, and the cost depends on the selected generation options.

Write the parts that should stay

List the things that define this particular room. For example:

• The visible walls, doors, windows and room proportions.
• Furniture you already own and intend to keep.
• Existing flooring, cabinetry or other finishes outside this project.
• The camera angle you want to use for comparison.

Be specific about what “keep” means. “Keep the sofa” is less precise than “keep the existing sofa in its current position, with the same shape and dark fabric.”

A prompt is a request, not a lock on the image. After generation, check that the features you asked to preserve actually remain. Treat an altered window, stretched room or changed furniture shape as something to correct, not evidence that the real room can change that way.

Give the change a clear job

Instead of listing every style you like, choose the decision you want this version to help with. Perhaps it is whether a lighter rug works with your dark sofa, whether curtains soften a bright room, or whether a restrained palette makes existing furniture feel more coherent.

Try one of these briefs, adapting the objects and finishes to your own photo. They are example instructions, not tested before-and-after results.

Brief 1: Refresh a living room while keeping the sofa

Restyle this living room with a warm contemporary palette. Keep the visible walls, windows, doors, floor and room proportions. Keep the existing sofa in its current position with its current shape and fabric color. Explore a light neutral rug, linen curtains and a small number of warm wood accents. Keep the original camera angle. Avoid adding built-in cabinetry or decorative clutter.

Use this when the main purchase is already decided and you want to explore the surrounding look. If you are still deciding the sofa's dimensions, check its footprint in a measured room plan first.

Brief 2: Soften a bedroom without changing the layout

Give this bedroom a calm, understated look. Keep the bed, existing furniture positions, windows, doors and flooring. Explore soft neutral bedding, curtains and a small number of decorative accents. Preserve the room proportions and camera angle. Avoid moving the bed, adding architectural features or covering the windows with furniture.

Use this to compare materials and color around an arrangement you already want to keep. Check the generated image against your source photo before deciding which details to develop.

Brief 3: Furnish an empty room as a visual concept

Create a restrained contemporary furnishing concept for this empty living room. Keep the visible architecture, flooring, windows, doors and camera angle. Add a sofa, coffee table, rug and a small amount of styling. Keep the arrangement visually simple and leave the visible door openings unobstructed. Avoid changing the room's finishes or adding windows, walls or built-in features.

Open this brief in Studio

Use this to explore a furnishing direction. If you share a virtually staged image in a property context, label the furnishing as virtual and preserve an accurate representation of the real property's condition. The generated picture does not verify that the proposed furniture fits.

Compare one decision at a time

After the first result, compare it with the original photo. Check the features you asked to keep, then look at the specific change you wanted to explore. If the rug works but the image changes your sofa, make the next brief about preserving the sofa and refining the rug. A completely new style request would make it harder to judge that decision.

Keep your measured layout and the visual concept together. An attractive image can help you discuss a direction; dimensions, product specifications and checks in the real room still determine what you can buy and install.

Before you generate

Have your photo, your keep/change/avoid brief and one design question ready. Review the displayed model, number of options and credit estimate. Start with the version that helps answer that question, then decide whether another generation is useful.

Bring your brief to the Studio: start a room restyle. For physical furniture fit, manual room planning starts free; AI generations use credits.
