ᐅ Parapet heights different within the same room?

I have a quick question and would like to hear your opinion. We are about to give final approval for our plan, meaning we are about to sign the sample selection protocol.

So far, this is our situation: in the rooms on the upper floor, for example, in the bedroom, we have a floor-to-ceiling window with a fixed transom, and on the adjoining wall, a large window that is 2.50 m (8 ft 2 in) wide and 85 cm (33 in) high. The architect says it looks odd if the sill height of the long window is lower because then the top edges of the floor-to-ceiling window and the long window won’t align. But if I make the top edge of the long window level with that of the floor-to-ceiling window, it results in the following sill height:

223 cm (7 ft 4 in) top edge - 85 cm (33 in) window height = 138 cm (54 in) sill height

Is this the correct approach, or can the long window be positioned lower without it looking strange?

I hope you understand what I mean….

Thanks in advance, greetz Ecko

Going any higher isn’t possible; it’s already fully extended at 223cm (88 inches). The remaining difference up to 255cm (100 inches) is due to the external venetian blind.

Or we simply make the children’s room windows facing south 300cm x 140cm (10 ft x 4 ft 7 in)... then the window sill would be at 83cm (33 in), plus 13cm (5 in) for the frame, so the view height would be 96cm (38 in), but that would already be really large windows!

I completely agree with the architect. The strip window is not a lookout but simply a strip window. Different heights would probably look quite awkward both from the inside and the outside.

The window area seems way too large for the room to me. It will get quite warm in there. Enjoy the sweating.

You have quite a mixed selection of windows on the facade. Also, it looks like you plan to use strips of windows as viewing openings, as apokolok called them, which in my opinion kind of misses the point.

Which side of the facade do you mean? Well, whether the windows are 300 x 110 or 300 x 140 as planned, there isn’t much difference. And no, we haven’t planned any strip windows as lookout points; my wife just wants to be sure not to make a mistake with the parapet height. We are already aware that a strip window is not a lookout. The strip windows are only on the north side and east side anyway, so in the bedroom and bathroom.

Therefore, the recommendation is to consistently place clerestory windows high up. Who might look out from there is not really relevant. It’s about allowing daylight in, not about serving as a lookout.

The dimensions mentioned represent an increase in window area of 27%. That is quite significant. For a room of approximately 15m² (160 sq ft) facing south, this results in a very high amount of heat gain.
