I'd be going back to the architect/designer and asking why the vent wasn't on the plans then armed with that info, I'd be asking your Turkey of a Supervisor why if it wasn't on the plans he didn't flag and insist on being given the EXACT code that he's referencing (including the details so that you can review yourself) as last time you checked YOU WERE THE CLIENT - It's a shame you've had this happen - your home looks as though it will be stunning, but others have said it wont be so noticeable when the building is done completely. The placement kind of makes sense since heat rises so you'd want it to be as close to the highest point for maximum effectiveness but you should have been aware. Check on the builders itemized estimate to make sure that you didn't miss it by accident so that if you did accidentally miss that one line item on a list of a million you able to prepare your argument accordingly.

Clau2000 our manufacturer was in Melbourne, supplier in Canberra. Despite being happy with the product we really struggled with the level of service from the supplier. Quite frankly the business owner was rude, uncommunicative and very difficult to deal with and I would hesitate to recommend her business to anyone. At one point we contacted the manufacturer but he insisted we had to go through his ACT supplier and could not order directly from him (either us or our builder). Our first set of windows were installed on a westerly facing wall & get direct sunlight for the hottest part of the summer afternoon, they have been installed for 4 years and are showing no sign of deterioration. We went with E10 glass, double glazed and they do an amazing job of blocking the summer heat.

Sorry Darlene but that's just no good...........a big part of the problem here is your trying to keep the cut out alfresco/outdoor living that is at odds with the style you are trying to work with, and it's causing the squeeze/compromise to the main central internal living spaces. There's nothing wrong with this type of thing in concept but they require experienced hands to resolve elegantly as opposed to a clunky way.... Refer to the plan I posted earlier - there is not one dogleg to be seen. paths of movement are streamlined and neat and proportions and alignments are balanced. What you've proposed above here walking straight into the dining area is not a good option and it makes your house feel smaller - this may be justified in situations say when you have no space in an apartment or unit scenario.........your on 2 acres or something? - your home should feel appropriately scaled and with space to breathe....... There are different plan configurations that will meet your particular brief requirements but the problem you have is that you are locked into this particular perimeter that has developed and then in the process of trying to sort it out you keep forcing/rejigging everything within the same shape/format that is actually not a fixed thing Here are your options: (a) seek some pro design guidance with a professional who understands the style/language you are working with - but don't be surprised if the nominated budget is exceeded in a custom format (b) explore some alternative options what siri & I suggested in considering off the shelf solutions of similar style that may be more aligned with your budget (c) keep going the way you are doing your head in fumbling around trying to DIY design your home but clearly falling short of your vision Best of luck!

i have to say that paying cash for a job so that the worker can avoid including payment for their tax and GST is illegal and party to fraud ..the extra payment is not for your invoice it's a savings for you so that they don't have to include the payment or GST in their income for tax and i think that expecting a quality job for work for which you haven't received an invoice or receipt is unlikely and they've already produced bad workmanship twice... i wonder if they repaired the dampproofing and flashing around the window and if you will have a similar problem in future?..i would patch up the grout and clean off the tiles and keep an eye on the wall so that if/when the leak returns you're ready to employ a professional to do a quality job
