The Changes a Render Makes for Free Are the Ones That Cost Most

How it works

The photograph is scaled to about one and a fifth megapixels and repainted at a moderate denoise. The instruction splits the room into two lists. Fixed: the sink, the hob, the extractor, windows, doorways, every appliance, the camera view, and the size and position of every cabinet. Changeable: cabinet fronts, worktop material, splashback, handles, and paint.

The negative prompt is written as a list of relocations rather than of artifacts — moved sink, moved hob, relocated appliances, added island, changed doorway — because in this category the convincing failure is a moved fixture, not a malformed one.

The camera view is held for a practical reason: two images from the same viewpoint can be flipped between, and flipping is how you catch a cabinet that went missing.

Layout is the budget

Renovation costs sort into two piles that look similar in a picture and behave nothing alike.

Surfaces are the cheap pile. Doors, worktops, splashbacks, handles, paint — these are ordered, delivered, and fitted onto what is already there. They are also where nearly all the visual difference lives, which is the useful fact.

Services are the expensive pile. Water arrives and leaves under gravity, gas and power arrive on runs, extraction leaves through a wall. Moving any of them means lifting floors, chasing walls, and inspections. It is not the cabinets that make a kitchen expensive to rearrange.

This page is built to explore the cheap pile with the expensive one held still, which is the same discipline a kitchen designer applies at a first meeting. The image it gives you is therefore boring in the specific way a real plan is boring: the room is recognizably yours, and only the surfaces have changed.

What a render still cannot tell you

Even with the layout honest, three things stay out of reach, and they are worth knowing before you make a decision from an image.

Color under your own bulbs, which the repaint page covers in detail — a warm cabinet front under warm LEDs is not the sample you saw in a showroom.

Material behavior, which is invented here. A stone's veining, a wood's grain, the exact gloss of a lacquer: the model produces a plausible instance of the category, not the slab you would receive.

And every non-visual property, which is most of the decision. Whether a worktop stains, whether a handle is comfortable, whether a matt door shows fingerprints. An image is silent on all of it and does not look silent.

When to use the redesign page instead

If what you want is a different kitchen rather than a different finish, this page will frustrate you, because it is built to refuse exactly that.

The room redesign page runs at a much higher denoise and will happily reimagine the whole space. That is the right tool when you are at the stage of deciding whether you like a style at all, and you have not yet asked what it costs.

Use it first, then come back here once you know which direction you are in. Direction is a mood question; finishes are a decision question, and they want different tools.

Publication gate

This page ships once the workflow has been run against a galley kitchen shot down its length, a wide-angle corner view, a kitchen with an island already in it, and a kitchen with a window directly over the sink, with cabinet doors counted and fixture positions measured against the source in every case.
