What you should have is something like this:

The rangehood ducting should be attached.
You should also have those for the bathroom exhaust fans.

Yep that's a "stink pipe" or sewerage vent pipe.
The rangehood vent will be a large 100mm roof cowl.
The problem is more likely to be the actual rangehood.
Unfortunately to get adequate…

That looks like a waste water vent pipe. check your eaves to see if you have a vent there, or, the rangehood could be ducted into the roof space? Only…

Yes appears normal to me. When the landscaping is complete you will not even notice it.

brightstarshine I was naive like you with my recent Metricon build. I thought I just sign the contact, pay the money, leave…

Sorry chippy, but I disagree with this in regards to internal doors.
All doors should be sealed.
I've had a couple warranty claims in the past (solid and hollow core) where…

I've asked the builder, they have gone all silent since they don't like answering any questions I send them on email. Honestly, I've have asked the BI only for a…

There is a procedure in your building contract to be followed. If your are on a standard building industry contract then your independent inspector is not recognised and has no…

I have added 2 photos of our house - one before painting
