Hi Cynthia 1. agreed ... although I would just raise the small concern that this will be a large master bedroom which we hope will be impressive and attractive on any future sale. Therefore we would like to avoid as far as possible, anything which makes one end of the room look a bit unusual (i.e. one obscured window not matching other clear windows). I am hoping we can come up with some internal (or possibly even external) design idea to mitigate the actual difference in window glass. One idea has been to use folding plantation shutters for example and to have the top 1/3 of windows (above the 1.7m threshold) as openable. However given the windows are dormer, the top 1/3 has the sloping roof, so cannot fit in plantation shutters around the top 1/3. 2. agreed again ... but again for future use by other occupants, it may seem strange to have a room with only obscured glass (or at least the main window pane up to 1.7m). Wondering if there are any design ideas which can make it look more like a normal room even though 3/4 of the window pane will be obscured. 3. that could be possible, I was thinking it would be a problem since the size matched (as usually I've seen the staircase window when stained glass being of a totally independent size and shape and therefore one does not even expect it to match, as it is unique in every way). However, here it is not only the same size and shape but also part of a horizontal row of windows, so I would think maybe the eye would expect matching styles across the plane? Would love to see a photo of exterior of a house where one of the windows in a row of similar sized windows is stained, if anyone can share? 4. The last window will continue to have regular glass as is it part of existing (pre-renovation) house and in any case (although difficult to see from drawing) set back from the 3 new windows by about 2m (you can see a flat roof in front of it). Therefore less of a need to imagine it would match as it is on a slightly different plane to the other three. Will definitely consider Solatubes for the study room ... hoping this is not another planning authority approval issue!

We don’t know for sure what type of windows but I like your idea of a cafe- type use of the opaque glass. Thank you

Is the roofer a subcontractor of the builder, or an independent contractor? If he's a subcontractor I'd be very unhappy with your builder's response! It looks like there may not be enough lead there to wrap around the ledge. If there isn't, the roofer will need to do it again with a new piece. If there is, presumably he needs to tuck it underneath neatly and fasten it in properly so that the water will drain off it properly into the gutter. I don't know exactly how it's supposed to look - we have lead around ours too but it doesn't finish on a ledge in the same way, it;s just a neat straight line under the window which then meets the roof. The difference is that ours looks neat all over and there are no flappy bits!
