I'm sure there's plenty of confusion about the why's and wherefore's of house orientation. The reality, as I have recently discovered, is that if want to live in an area that is older, developed, close to facilities, you take whatever orientation the block actually happens to be and do the best you can with it. Unless you're out in the country, or buying something in a new estate, you may not get a choice of orientation: we certainly didn't. And yes, our garage does have the best aspect - because there was nowhere else to put it - it had to face the street - but we live walking distance to shops (think of the petrol saved on not having to get into the car), we've got clerestory windows on the west side so no afternoon sun issues, and we're assembling a collection of sails for the south side, where the deck is, to provide shade from the late afternoon sun. Oh, and skylights for the kitchen. No, not ideal. But the location is, and the designers have worked around the constraints of orientation. And that's reality for a lot of us.

You have an ensuite and an identical bathroom around 3 steps further apart. Can't see any advantage for this. You could lose the ens, relocate the WIR and end up with a bigger bedroom, bigger WIR and save money. Your roof has these eaves all close together over what appears to be some upper level windows, but these walls aren't reflected below. If I've understood this correctly you've added significant build cost for little gain. I think the room sizes are ok but I would suggest a design professional to polish it up.

The first thing I would suggest , would be to keep your lawyer 'in the loop' -- don't immediately threaten the builders with lawyers , but explain things and get their suggestions , and the lawyers too . $1000 of advice may be invaluable , but spending $20k each on lawyers maybe not ? As far as the plans go , you already have a 2nd WIR in the room as far as I can see -- so if 'all else' fails , you have that , and maybe a $150 self-assembled back-up in the garage if needed for seasonal clothes ? I'd try and delete all of WIR 1 -- for space but also slightly easier access to the ensuite . Not ideal , but may suit you better ? And probably too late now , but with someone with access limitations , possibly a door direct into the WC would have been beneficial too -- like I said , only minor , and presumably too late now , or not needed , but just another opinion . All the best !

Well, I had a structural engineer come to the house yesterday at a cost of $600. I thought I would get drawings or something for that price but this is what he said.....(oh, before his visit, I cute into some of the plaster of the dividing wall between kitchen and lounge and the brick wall goes all the way along the wall). Structural engineer said that the wall is load bearing because he think that it provids support the support rafters (or what the horizontal beams that are at the bottom of the cathedral ceiling). Those horizontal beams that go across the house (each one from back to front of house) and partly supported by the brick dviding wall. He said that if I totally removed the overhead walkway, I would still need to leave a post or some of the brick on either side of the current dividing wall , as well as a support beam between them. He said I could cut out a window into the wall, but the bigger the window the bigger the horizontal support beam would be required. He said he didnt like working with brick because it was not like timber etc, where you can calculate what load it takes. He said there can be a lot of variation in a brick wall. He said that I should contact a building designer (someone who can give an idea of design whilst also consdiering loads and being able to draw plans...he said normally, those people will ask his advice on something). I hate tryin to do renos, because you can spend a lot of money and not really get much from it, and also go in circles about knowing who is the best person to contact. I know I do need someone to help give me an idea of design, but someone who also takes into consideration comparative costs including structural elements/loads etc. When I said to him ..so I shouldnt see an architect, he said that he often sees things from architects with no technical drawings...just design only. I really would like to be able to see the view at the back from anyway in the house, but I am a little bit reluctant to move plumbing, as I imagine with a concrete floor, the costs will start to rise significantly if plumbing has to be moved. I tend to spend most of my sitting outside time, at the back of the house, looking at the lake...even though there is only 1.5metres from the back of my property to public land (and that I have to put fencing up there to keep my dogs in). It is only me and my dogs at the place, but I do want to make sure that any changes that i make are family friendly and AirBnB friendly. The exisitng laundry seems to have heaps of wasted space in it and because the current windown is so high in it, it seems to be very segregated from the outside pool and not in the best place. I dont know what to do with this place.
