The ground floor in June

Hours of direct sun through the glass, at the middle of each floor. Stand at a window and it is a different number, which is why the windows are listed separately.

The light in June where each plant actually stands, against that species’ own range. Nothing here is set by hand.

The sun’s position is exact — the disc and the arc are where this house’s sun is on that day, at that hour, on the same north the plinth points to; only its distance from the house is a drawing convention. Light through a window is our simulation of the room, not a reading taken in it: good geometry, no bounce, no doorways yet. The light classes and the growing ranges are horticultural conventions, each with a source. A window one floor up lights that floor and no other, and switching a storey or a layer off changes the picture, never the light.

Two floors. One sun.
