A small hard-hatted worker is out there right now, stacking blocks and pouring foundations, and flatly refusing to tell anyone what the plan actually is. That is where you come in.
Each question drops you onto a site mid-build, with only the clues laid down so far: the shape of the base, the angle of a wall, the tools left lying around. Read them, make your call, and move to the next lot. Guess well and the finished skyline is yours to claim. Guess badly and you will be admiring a very confident pile of bricks.

The cyanotype was described by the astronomer John Herschel in 1842. Paper is coated with iron salts, a translucent drawing is laid on top, the whole thing is exposed to daylight and then washed in water. Wherever light struck, the paper turns a deep Prussian blue; wherever a drawn line blocked it, the paper stays white.
That gave builders something they had never had: exact copies of a drawing, cheaply, without a draughtsman tracing each one by hand. Diazo prints with blue lines on white paper took over in the middle of the twentieth century, plotters and screens took over from those, and the word blueprint outlived all of it.
A building is at its most readable before the cladding arrives, because you can still see what is carrying the load. An arch pushes outwards as well as down, so it needs a buttress or a tie holding the base together. A truss converts a long span into triangles, since a triangle cannot change shape without changing the length of a member. A steel or concrete frame carries everything down through columns, which frees the walls to be glass, curtains or nothing much at all.
Roof pitch is mostly climate written in geometry. Steep roofs shed snow and heavy rain; near-flat roofs suit dry places and often double as usable floor space. Window rhythm gives away the floor plan behind it, since evenly spaced identical openings usually mean repeated identical rooms.
We read half-finished buildings the way we read half-finished words, by matching a partial cue against a stock of familiar shapes. Someone who has watched a timber barn go up will name the frame in a second, not because they have an architectural gift but because they have seen that skeleton before.
Which is the honest framing for the questions below. They reward familiarity with common structures and a willingness to commit to a guess. Treat any score as a bit of fun rather than a verdict on your spatial reasoning.
