単斜屋根の集水：降水量による断面

Design a coastal house in the manner of Glenn Murcutt's Magney House — a long thin plan on an open grassy headland with a butterfly roof of two shallow curved planes falling to a central gutter, shaped so the whole roof collects rainwater into tanks because the site has no mains supply. Compose a low linear house with a corrugated steel roof dipping to a valley in the middle, slim steel posts and rafters, full-height glazing on the sunny side with adjustable blinds, water tanks alongside, wind-blown grass and the sea beyond, bright clear Australian light, eye-level long view, 28mm lens, architectural photography, ultra photorealistic, 8K
