I'm not a builder, but I'm guessing that getting a tank plumbed to your toilets after handover might be tricky and expensive relative to doing it during the build. You…

Wow your backyard is looking great!
Was going through some of your pics and noticed I couldn't see any powerpoints in your ensuite, did you have some installed in the vanity…
