The recipe is the style, not the picture. Put your own subject in and the highlighted part of the prompt changes.

Prompt

An interior painted in flat blocks of opaque gouache, walls, doorways and ceiling described by little more than abutting rectangles of ochre, cream and warm grey. Approximate and slightly incorrect perspective, brushy edges rather than ruled ones, one lighter passage standing in for daylight arriving from outside the frame. No furniture detail, no people, no line work.

The prompt gets you close. Feed one of the examples in as a style reference for the rest. Download the images

Tips

1Slightly wrong perspective is deliberate. Correct it and it becomes a rendering.
2One lighter block does all the lighting work.
3No furniture detail. The room is shapes.
