Claims a corner and quietly draws a boundary around the sitting area.
A corner turns the run 90°, and the shape letter follows from those turns. Two right turns make a room with three sides; one right then one left splits a space in two.
Nobody lists this exact shape yet. Ask the workshops that do cover you what they would charge — it costs nothing and commits you to nothing.
Your request goes to every workshop covering your country, and their replies land in one place.

Prices only appear once we know where it has to be delivered — a shape one workshop already builds may be out of reach of another.
Nothing is saved anywhere. The address bar holds the whole design — bookmark it, or send it to whoever else has to agree to it.
