I have high ceilings downstairs 2.7m and std door and window height and looks fine but do have wider front door 870mm don't like tall and skinny doors. Having said that on one wall do have higher windows and they look fantastic but that was to catch sun and block out ugly neighbour house so std window size just fitted higher but look so good in my downstairs open plan area could have gone larger height windows all around but don't have verandah across front house that would look odd with higher windows and no light benefit and more heat n cold thru glazing. Good luck with your decisions

Looking at the first below I'd say, to be on the safe side, the bedhead should show half to three quarters above your tallest pillow. The second photo I believe shows too much bedhead.

Thanks all for your advice. Ive included some renders that I made with view along the corridor with and without the bulkhead. I don't think renderst does it justice until you actual walk through @ frame stage. I agree that ceiling height and comfort and look, depends on climate, orientation, insulation, relative proportions of other parts such as windows/doors. Because of the Melbourne climate, we have planned for double glazing, and good insulation with R2.5 batts wall, R6.0 ceiling. We have 2.4m height of windows and door around the ground floor which is btw 3 to 3.6m so I think proportion wise should be ok. In the family where it was always planned 3.6m from the start, we have a band of clerestory windows too. We have decided not to be too excessive with windows ( ie 3m and even 3.6m floor to ceiling - how grand would have that looked though! ) to minimise heat loss during winter. Energy rating for house is 7 stars so far. Thanks for giving me the pro and cons - I have some more confidence to let it stay at 3.6m throughout now.

There are so many variables and ways to build things. Building succesfully is very much working well in three dimensions and understanding the structure, and the waterproofing required in three dimensions. Your question suggest that you are only thinking in terms of heights and brick courses, but there are lots of other things happening that would suggest that you get a section of the house and post it with dimensions. Most building professionals work in millimetrres rather than brick coursing. So converting your dimensions to millimetres - 28 courses is 2400mm, which is the minimum height for a habitable room ceiling. Six courses of brickwork is 514mm for the window opening, however your glazed area will be less than this due to the width of the window frame. Your 3 courses of brickwork which is 257mm should be enough for most steel lintels, unless you have a really wide opening for a window? You also need to allow for flashing if the clerestorey is above another roof running into the same wall - if this is the case you may need the full 47 courses. I would be asking your designers why they need 47 courses, as it is a lot higher, and there may be problems with setback issues? Is it a flashing issue? Is it a window opening width and lintel issue. I am afraid you haven't really supplied enough information or images to explain about the clerestorey window so it is impossible to answer precisely.
