AI concept visuals for architecture and interiors: from a one-line brief to a client board

A client says "something warm, a bit Scandinavian, lots of light" and expects to see it by Thursday. Before AI stills, that sentence became a day of pulling photographs from other people's projects and apologising that none of them were quite it. Now it can become six pictures of a room that does not exist yet, made to the brief, in an afternoon. This post walks one such brief through the studio step by step: what to generate first, how to keep a set coherent, when to bring in a clip, and the line where a concept visual must stop and a drawing must begin.

What a concept visual is for, and what it is not

An AI still is a mood, a material palette and a quality of light that a client can react to. It is not a plan, a section or a rendering of a modelled building. The model does not know your site, your setbacks or your ceiling height, and it will happily draw a staircase that leads nowhere. Used honestly, that is fine: the job of a concept board is to settle direction before anyone spends a week in CAD. Say so on the board, in writing, and nobody will later measure a window from it.

Step 1: translate the brief into picture words

"Warm, Scandinavian, lots of light" is a feeling. A model needs nouns. Write down the space, the materials, the time of day and the camera before you open the composer, in that order, because the prompt guide is right that what comes first in the sentence gets the most weight. For the brief above the translation might be: a living room, pale oak floor, white lime-washed walls, a wool sofa in oatmeal, low winter sun through a tall window, a camera at standing height looking across the room.

Step 2: explore cheaply, then commit

The first renders are for finding the composition, not for the board. Run the prompt on Still Lite, from €0.30 a render, and make a handful of variations: swap the camera position, the time of day, the floor material. Look for the one that feels like the brief. Only then re-run that exact prompt on Still at €0.40 for the picture that will be shown. The re-roll arithmetic is the same here as anywhere: pay the higher price once, for the keeper.

Step 3: hold the set together with a reference

A client board with six rooms that each look like a different house is worse than one good picture. Once the first still is right, attach it with + Reference before generating the kitchen, the bedroom and the bathroom, and tell the prompt what the reference is for: "same materials, same light, same photographic style". The model inherits the palette and the mood, so each new render only has to get the new room right. How a reference guides a render, and what it will not copy, is in the reference guide.

Step 4: material studies as a grid

The most useful board we have seen a designer make was not six rooms but one room six times: the same prompt and the same reference, with only the floor and wall materials swapped between renders. Oak against terrazzo, lime wash against raw plaster, a brass tap against a black one. Clients who cannot say what they want can almost always say which of two they prefer, and a grid of controlled changes turns a vague conversation into a series of small decisions.

1. 01Fix the camera and the light in the prompt and never change them within a study.
2. 02Change one material per render and name it precisely: "honed grey limestone", not "stone".
3. 03Keep the keeper from each pair as the reference for the next, so the set converges rather than drifts.
4. 04Choose the frame for the delivery: a wide landscape for a slide, a square for a message, as the aspect ratio guide lays out.

Step 5: one short clip to sell the light

Light is the thing a still cannot quite show. Take the best interior still, attach it as the start frame of a clip and ask for very little: "sunlight slowly moves across the floor, dust in the beam, the camera does not move". A clip of a few seconds on Motion Turbo, from €6.30, does more for a pitch than another three stills. Keep the motion to the light and the camera still; walls that move are the failure mode, and the motion prompt guide lists the words that cause it.

Where the concept must stop

Be plain about the limits, with the client and with yourself. The studio cannot produce a drawing to scale, a floor plan you can build from, or a faithful rendering of a specific model you have already built in your own software; for those, keep using that software. Furniture, fixtures and fittings in a still are inventions, not products you can order, and a logo or a brand-named tap will not come out right. Counts and dimensions drift: ask for "a row of tall windows", not "four windows two metres wide". Text on signage will be garbled, so leave it out. And a concept picture of a listed building or a neighbour's house is a picture, not permission; the planning conversation is still yours to have.

Within those limits the economics are hard to argue with. A board of six coherent concept stills and one clip costs less than an hour of a visualiser's time, there is no plan to pay for, and a failed render refunds itself to your balance. The prices for every image and video model are on the models page, and the composer shows the exact charge before each render, so a study never costs more than you decided it should.
