AI room designExpert analysis

It starts from your photo, not from a floor plan

Repaint a wall, change a floor, furnish an empty room or swap the furniture that is already there — on a photograph of the actual space, with the geometry left alone.

AI room design works from a photograph of a room that already exists: you upload the frame, and the model returns the same room with different paint, flooring, or furniture. That single constraint separates it from a room planner, which starts from an empty rectangle and asks you for dimensions. One shows you your room differently; the other builds a room from measurements. Knowing which of the two you need is most of the decision.

Interior room redesigned from a photograph with new finishes

The walls, windows, ceiling height and proportions are the original photograph. Only the finishes and furnishings changed.

What an agency needs to take away

The essentials of this analysis, in one read.
AI room design starts from a photo of a real room. A room planner starts from dimensions you type in. They solve different problems.
The changes that work reliably are surface and furniture changes: wall colour, flooring, furnishing an empty room, replacing existing furniture, and conservative finish upgrades.
What it will not do is measure anything. There is no scale in a photograph, so nothing it returns is a plan you can order materials against.
CasaNova's free plan is 10 transformations per account, plus 5 more for completing your profile, with no credit card required.
An account is required to use it. That is worth knowing before you start, and this guide says so rather than burying it.

Who gets a useful answer out of this

AI room design is most useful when the room exists and the decision is reversible on screen but expensive in reality.
Homeowners deciding on a paint colour or a floor before buying materials, who want to see it in their own light and their own room.
Renters and buyers looking at an empty or badly furnished space and trying to picture what would fit.
Agents and photographers who need the same thing for a listing, where the audience is a buyer scrolling a portal rather than the person who lives there.

The changes CasaNova actually performs

Each of these is a distinct transformation rather than one general-purpose prompt, because the constraints differ: repainting has to preserve texture, reflooring has to preserve perspective.
Wall painting — repaint interior or exterior walls while preserving the surface texture rather than flattening it into a colour fill.
Floor replacement — swap the floor material while preserving perspective and geometry, so the plank direction still follows the room.
Furnish empty room — place a coherent set of furniture into a space that has none.
Furniture replacement — swap the furniture already in the frame for a cohesive set, which usually reads better than starting from empty because scale is already established.
Room finishing — upgrade paint, flooring and fixtures together, conservatively, when the room needs a general refresh rather than one change.

AI room design vs. a room planner

Search volume lumps these together, but they take different inputs and return different things. Pick by what you have and what you need out the other end.

What it saves, honestly

The value is not the picture. It is the decision you avoid making blind, and the cost of getting that decision wrong physically.

Paint

Seeing a colour on your own wall, in your own light, before buying it. Test pots and a repaint if the colour is wrong are the alternative.

The comparison is a render against the cost and the weekend of doing it twice.

Furniture and layout

Seeing a room furnished before committing to a style, or replacing furniture that is dating the space in every photo of it.

Cheap to iterate on screen; expensive to iterate by delivery van.

For a listing

The same transformations applied to listing photos, where the audience is every buyer who sees the property online before deciding whether to book a viewing.

CasaNova's plans include a monthly credit balance — €99/month for 100 credits, sized on 10 properties at 10 photos, then spent as the month requires.

What AI room design will not do for you

The honest limits matter more here than in most categories, because the output looks authoritative whether or not it is.
It does not measure. Nothing it returns tells you whether a sofa fits — a photograph carries no scale, and the model is not inferring one.
It does not produce a shopping list. The furniture it renders is generated, not selected from a catalogue you can order from.
It does not do structural change. Moving a wall, adding a window or reconfiguring a kitchen is a renovation drawing, not a photo edit — and presenting one as a property's current state on a listing is prohibited by MLS rules.
It does not replace a designer on a project of any complexity. It answers 'what would this look like', not 'what should I do'.
If you need to publish the result on a listing, the image must be identified as digitally altered. Our virtual staging definition guide covers what the rules require.

The four changes, on real photographs

Same room, same frame, same light in each pair. Only the surface or the furniture is different.
Before
Room before a wall colour change
After CasaNova
Same room with a new wall colour applied

Wall painting: the colour changes, the texture and the shadows on the wall do not flatten out.

Before
Room before a floor material change
After CasaNova
Same room with a different floor material

Floor replacement: perspective and plank direction follow the room rather than the image plane.

Before
Furnished room before furniture replacement
After CasaNova
Same room with the furniture replaced by a different set

Furniture replacement on an already-furnished room, where existing scale anchors the result.

The deciding point

What genuinely makes the difference when an agency compares two visual workflows.
Business decision
AI room design works from a photograph of a room that already exists: you upload the frame, and the model returns the same room with different paint, flooring, or furniture. That single constraint separates it from a room planner, which starts from an empty rectangle and asks you for dimensions. One shows you your room differently; the other builds a room from measurements. Knowing which of the two you need is most of the decision.
Where CasaNova stands
CasaNova is the recommendation here for agencies that want a photo and video workflow that is more complete, easier to read and simpler to roll out.
