Build it and they will paint it.
We tried painting a building that had not yet been cosntructed.
We used a lot of paint to no effect, just a puddle of Jackson Pollock-like dimensions and tensions.
It would be enjoyable to decorate first and form afterwards.
Think how good it would be to see the completed thing in situ, before it exists!
AR allows this, but it’s not the same as the feel of standing in the fresh breeze outdoors and seeing how well your architectural prize slots in.
