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!!

Same brand as the one you have only a lot older obviously. Never left dark soot marks on the walls...that's not good. It should be vented. I remember as a kid being able to operate it- it was fan forced, vented and heated the entire house. Perhaps needs a service/filters cleaned ?...Service it if you plan to keep it, who knows the last time anyone did this??. We've never run our ducted systems in Winter, too $$$. I've always looked for alternate heat sources to keep bills down, that's why I suggested to get a price for an oil delivery. If oil is astronomically $$$, probably get rid of it, use your ducted. I remember we would get our oil delivery at the start of Winter, sometimes a 2nd one at the end if it had been a particularly cold Winter. Hope this helps.

check with the maker of your wood heater and with their specific guidelines you may be able to have a built in arrangement around the heater although the flue will need to be enclosed with a frame and wall cladding to have the mantlepiece which would then project a long way into the room? but, unless the maker guarantees the safety of your fire enclosed under their guidelines i suggest you may be better off to consider a new heater specifically designed to be built in with a flue that can be directed horizontally through the wall or up through the old space behind your heater but they must be installed by experts to ensure safety

answering your questions: change the sliding door to a bench height sliding window and use the salvaged sliding door in the western end of the dining room where the best entry position is for the deck, you MUST have a proper legal drains do not consider anything else...the drain pipe for the garage laundry can be on top of the concrete floor, behind the washing machine and through the sink cabinet and/or under built in storage and only needs a few cms not a whole floor and no stepped up area that you would see or trip over.. the laundry can't be in a separate room as there's not enough space for a separate laundry without compromising the size of the garage...a laundry cupboard 80 cm deep is enough for the washing machine (allowing for the drainage pipe) you could use the old line cupboard to store anything you want but it's not cost effective to change, the entry foyer is already as big as in many modern homes and there's generous flatpac biw space in the small study.... the family bathroom is 2380 x 2370 (ie the old study minus 1m for hall way and wall thickness and, arranged exactly as shown to allow for the wide window there should be space for a bath up to 1800 x 750, vanity about 1200 x 500 and shower space 1200 x 800 and leftover space makes the small linen cupboard with the door deliberately opening towards the shower to use the back of the door for hanging racks for towels and clothes....btw i understood your priority was maximizing separate sleeping rooms and minimising costs...my last plan has five separate sleeping rooms plus the lounge with sofa bed totalling sleeping places for at least 10 people plus the potential for bunks in the garage so you need to decide what is most important and where you're prepared to compromise
