Simulate a facade renovation with AI

A photo of your house goes into three Image nodes that renovate it three ways: pale render with anthracite joinery, timber cladding, external wall insulation. The full workflow is visible here, no account needed.

The real workflow: the photo of the starting facade wired to three Flux Kontext nodes, one renovation approach per node. The three renders are the demo's own, taken from the pavement.

A facade renovation is decided on a colour swatch ten centimetres across, and regretted for twenty years. This workflow replaces the swatch with three images of your actual house: the photo taken from the pavement goes into three nodes that each renovate it on a different approach, with the same volume, the same openings and the same viewpoint.

The first project is a classic render job, off-white lime render and anthracite joinery. The second mixes white render with vertical timber cladding and dark green joinery. The third shows external wall insulation, with its white surrounds and its deeper window reveals, that is to say the job that changes both the look and the bills.

On a facade, anything that moves shows: a window shifted by twenty centimetres, a roof pitch straightened, a floor added. The locked half of the instruction is therefore the longest in the catalogue, and it is what gives the render its value. Flux Kontext edits your photo instead of inventing another one. The three renders cost eighteen credits.

How it works

1
Shoot from the pavement opposite
Frame the whole house and a little sky, holding the camera straight. Step back rather than zoom: too tight a frame cuts the roof off, and the render invents what it cannot see.
2
Wait for an overcast day
Bright sun leaves hard shadows that contradict the new render and give the montage away. Even light gives renders you can lay side by side.
3
Leave the list of locks in place
Volume, roof, chimney, openings, shutters, downpipes, steps, ground level, hedge, viewpoint. That paragraph is what stops the model handing you your neighbour's house.
4
Generate all three, then adjust one colour
"Generate all" produces the three projects. Then change the joinery shade in a single instruction and rerun that node: the other two keep their render and stay comparable.

Variations and use cases

The same canvas, tuned for different needs: each variation is two or three lines of prompt away.

The simple render job

Fresh render and repainted joinery are often enough to take thirty years off a house. It is the demo's first project, and the most common of the three in real life.

Timber cladding

Putting timber on part of the facade changes the perceived silhouette of the house. The render shows straight away whether the idea works on yours or whether it weighs the gable down.

External wall insulation

The job that touches both the look and the heating bills. The walls thicken, the window reveals get deeper, and that detail is exactly what the demo's third render shows.

Choosing the shutter colour

Anthracite, dark green, white: three renders of the same facade answer better than a colour chart held up at arm's length against the wall, because they show the whole surface.

Presenting a project to a builder

An image of the expected result avoids half the misunderstandings on a quote. The builder sees what you have in mind, and tells you straight away what is feasible and what is not.

A block of flats, a shop, a barn

Nothing in the workflow assumes a detached house. A shopfront or an outbuilding wall is handled the same way: lock what stays, describe what changes.

Common mistakes

Shooting from below

Step back two metres and hold the camera straight, and the vertical lines stay vertical. Otherwise the model straightens the house its own way and the render no longer looks like anything.

Framing too tight

If the ridge or a corner of the wall falls outside the frame, the model invents the missing part. Take the whole house with a bit of air around it, and crop afterwards if you need to.

Asking for ten changes in one instruction

Render, shutters, gate, drive, terrace, conservatory: beyond three or four changes, the model forgets some of them and moves what it had been asked to keep.

Believing the openings are fixed

They are, thanks to the instruction, not by magic. Rewrite the instruction without the list of locks and the model recomposes the facade as it sees fit.

Frequently asked questions

Is the render good enough for a planning application?

No. A planning application asks for drawings, sections and colour samples. The image explains the intent to your family or your builder, it does not replace any document in the file.

Can I impose a precise shade?

Yes, write the colour name or its reference in the instruction. The model approaches the shade, it does not calibrate it: for a final choice, compare with a sample held against the wall.

Does the house stay recognisable?

That is the whole point of the lock. The three demo renders keep the same volume, the same openings, the same roof, the same hedge and the same camera angle: only the surfaces change.

How much does a facade simulation cost?

Eighteen credits for the three projects, six per render. The cost shows on each node before you click, and rerunning a single project costs only six credits.

Can I simulate an extension or a conservatory?

This workflow is built for surfaces, not for volume. Adding volume means lifting part of the locks, and the render becomes far less faithful to your house.

My neighbour appears in the photo, is that a problem?

Frame so that only your house is kept, or crop before generating. The instructions ask for an image with no people, but nothing beats a photo taken when the street is quiet.

Does the render take local rules into account?

No, and that part is down to you. Many councils impose render and joinery shades: check the local rules before falling in love with a render.

Can I use it to sell the house?

To show the potential of the works, yes, as long as you say so clearly. To illustrate the property as it is, listing photo is the right sheet.
