I have a very wide room. In fact, in acoustic terms it might be considered infinitely wide, because each side is ultimately open, to the garden on one side, and on the other to a balcony which hangs over the edge of a rock drop-off. Both ends of the house remain wide open by day, and at night are closed off by insect screens, but nothing that will much constrain air flow.
There is a lovely cool flow through this room, from right side to left side — of air, I would say, though our home's previous owner, a yoga teacher, called it . So I am loth ever to pull across the brutishly heavy glass sliding doors and so sever that . It flows even during ‘Antarctic blasts’ (by which I mean any time Sydney drops below 20°C); only one side needs be closed even for heavy rain. In only two circumstances are all turns fiery; we seal in the night's cooler air and let the heat lick at the double layers of glass and insect screen.
