The house is taking shape

We visited the block over the weekend- the front timber windows have been installed, and the roof trusses are in. Unfortunately, the window frames (sashes) are not as wide as we would have liked, despite providing Greybox with measurements, photos of similarly wide-sashed frames, and having a thicker sash indicated on the plans. Note to anyone building: if it's not on the list of specifications included with your contract, or as a post-contract variation, technically, the builder is not obligated to build it! Even if it's on the plans, the specs in the contract take precedence. (Trust me, I've had many lengthy convos with Building Advice and Conciliation Victoria!)
