My new build will have a large-ish open-plan room and I am wondering what ceiling height would be best.
Its a perfectly rectangular room, 9515mm by 5174mm to contain, in a row: kitchen, dining table, sitting area. Its a modern bungalow and the roof above is flat. One unusual feature is that there is only a single external window in this big room, high on one of the short sides above the kitchen units. To compensate there will be at least two large roof-lights (each 2400 mm x 900 mm, flat glass), possibly three. Its a passive house so the roof will be thick (about 550mm).
What ceiling height will give an airy feeling with a sense of good proportion and no sense of claustrophobia?
The minimum of 2100 mm would feel too low, I think
What about 2400 mm?
What about 3000 mm?
I had originally even contemplated 3600 mm but it looks like that will make the ridge height too high, so I will not get approval
Advice appreciated.
