What generates the renders?

Google's Nano Banana image model, prompted with the plan's actual room sizes, material palette, and brief, so the render reflects the building rather than a generic house.

Is the sun study accurate enough to rely on?

Treat it as a design-stage indication. It will tell you that a room faces the wrong way; it will not replace a consultant's daylight modelling for compliance.

3D walkthrough and sun study

Every plan in Archi4D is a model, so the 3D views are not a separate deliverable someone has to build — they are another way of looking at the geometry you already have.

Five ways to look at it

An isometric cutaway for the overview, an interior render for the room, an axonometric for the drawing set, a long section for the build-up, and a sun study for the solstice. All from the same rooms and walls.

Daylight before a consultant

Daylight autonomy per room and north glazing area are computed from the geometry, and sun studies render raking shadows at the season and hour you set. It is enough to catch the dark bedroom while it is still free to move.
