Quick answer: The 3000 × 3000 mm square anchors support a Queen, work-first Queen, or Full with flexible desk. They are not interchangeable: the bed-centred option protects access while the work-first option gives the desk the better wall.

What changes between them?
Bed-centred is the calmer couple setup, work-first favours a regular desk routine, and open-centre preserves flexibility for a single sleeper.
Trade-off: A Queen in the square envelope leaves less spare circulation than a Full; the flexible plan gives up some storage certainty.
Before you move anything
The layout registry records a rectangle and its own door/window scenario. Treat the plan as a measured starting point, not a building-code drawing. Measure the outside of every bed frame, desk, wardrobe and chair operating zone. A mattress preset is only an anchor.
