Old post but thought I'd update. We have finally moved into our forever home and on occasions, obviously in winter, we still have crying window (sob). We have the wet windows on the south side of the home which is the shady side so not unexpected but also on the north side where we still get lovely warm winter sunlight streaming in and I still do have all my windows slightly cracked open and it does help. Incidentally I have glass bricks in our bathroom on the south side and there is no condensation on this window at all. Our home has insulation in both the exterior and interior walls and we have double insulation in our roof, so factor 7 unlike the usual factor 3.5 not that it probably has any bearing on the moisture issue. We have a 1.8mtr wide veranda surrounding the entire home so the windows are some what protected from the elements but when the temperature gets fairly low and can be almost zero in winter, it seems impossible to prevent this crying window sindrome but I can live with the fact it is fairly easy and quick to remove with a Karcher window vac now, brilliant little machine at $99 and it only takes a few minutes. We have an exhaust fan in both bathrooms that is vented outside so the moist air does not go into the roof space and in fact even my rangehood ducting is vented outside too!! We even had condensation in the roof cavity as well to the point of having a rainforest up there but since fitting another whirlie into the roof making it three in total now, it appears to have almost entirely eradicated that problem. I can say catagorically now that crying windows are a very difficult problem to eradicate in very cold climates where obviously the inside of the home being heated at night is going to create the perfect conditions for the condensation to settle with the inside being far wamer than the outside and there in lies the problem which canot be changed. I have blinds and curtains that I close ever day before dark but it makes no difference. As I have aluminium windows and doors throughout, so no timber anywhere, it isn't such an issue for damage but annoying none the less but life goes on and I do so love my beautiful new home!!

Thanks once again oklouise for your comments. I have already been told by the draughtsman that I cannot put in skylights. No idea if this is true but he seemed quite sure and it was he who 'designed' the layout of said ensuite with what I consider a too small window because of ease of plumbing and drainage. He says that can be changed...............Supposedly only put like that to get the oversize plan in fir consent. This department is only interested in the outside view and the effect on the neighbours, which I actually dont have any. The positioning of the ensuite and WiR has changed too from the first plan as I had to come 'out' of my bedroom into a corridor past the WiR door and then into the ensuite. Technically they were both in my bedroom as had not entered the hallway but did not seem like it. So the wall you have now suggested for the door is a small lobby to the bedroom and I had planned to put furniture on it and a full length mirror. I will now look again at the whole space with three zones to see what can be done. I used the word solar tube as I thought that was the generic name for the 'tube' installed which reflected light into a room. Do they cause draughts? Have had no experience of them but will probably want to install one in my scullery (or Butler's kitchen) but am going to work in it a few months before deciding that. I am really quite a novice about function of installations and of building code.

the only mistake would be not making the best of what you already have.. it's a great house and the size and location of windows can help improve PSD ...YourHome.gov has lots of ideas for improving design for existing homes with less than ideal orientation but depending on your local climate "north facing" isn't always ideal for every room.. we deliberately built a south west facing room because it's good to have light in all rooms, western sun is great in cold weather and overheating is easily controlled with insulation and external blinds and a south facing room will be easily cooled in hot weather ... a highlight window in your rumpus room will help brighten the room and allow for easier furniture placement and shade cloth roller blinds on the outside of the alfresco can shade western sun from kitchen and family living and dining areas...good luck with your build and enjoy your new home
