This isn’t an exam question. Our kitchen is 2.82m high, 3.46m wide. I’m replacing french doors with a new sliding door, which will be 2.5m wide (a 1.25m sliding pane and a 1.25m fixed pane). I’m struggling with deciding what the height should be. I thought a 2.5m square to let as much light into the kitchen as possible (have to leave some space above for new lintel), but my wife thinks the proportions are wrong and has quoted the golden ratio. I had to look that up & apparently to be most pleasing on the eye the ratio is 1.618. So if the width is 2.5m, the height would be either 4.045m or 1.54m. Clearly, both are impractical. She is suggesting 2.2m which is the height of the current french doors but I think that is a wasted opportunity to let more light in. Anyone here an architect/ have any advice?
