Canberra custom KDR

After an all-too-brief break, we're back for the new year.
The cladding was completed and rendered in early Jan:
Yesterday, we were on-site with the builder (and plumber and sparky and chippy,…

Pics from yesterday - the house roof is finished, the garage roof is almost finished, windows have gone in, and the cladding (NRG Greenboard, replacing the originally spec'd Exsulite) is…

Electric OR Gas ducted heating/cooling???

True, and that's why I asked what the cooling setup would be, to confirm if there would be one. However, I readily admit that, given that the OP is…

Presumably by 'electric system' you mean ducted reverse-cycle aircon? What would be your cooling setup if you went with gas?
Reverse-cycle aircon is a very efficient heater (moreso than gas), plus…

No worries with derailing this thread, happy to help! Make the most of the learning and planning time - when things start happening, they can happen much more quickly…

Good to see the progress photos!
Nice tile choice - how large are they?

No, I'm not in the building trade - just a hobbyist, basically, and a well-researched amateur (I first learned about passive solar building as a kid in the 1980s -…

I can understand your disappointment about not finishing before the year. Nice to see the progress, though, and the amount of activity that seems to be going on.
And at…

As it turns out, we've changed from Exsulite to NRG Greenboard. They're both the same basic product (EPS), but when we originally chose, Exsulite had a cavity system but…

Looks good. I like how you've customised the laundry to your specific requirements!
You mentioned some issues - is it just detail, i.e. is the actual layout of cupboards, benches…

Yep, the floor is looking great! Too bad about the rectification work needed - do you have any idea of how long it'll take?

The Proctorwrap is our wall protection membrane (I think you're using the Solitex Extasana, which has a similar purpose for Passivhauses). It's a vapour-permeable wrap that keeps external moisture…

Coming together nicely - good to hear that the insulation is doing its thing!

As of yesterday - my precious Posistruts :-D

Locked together with strongbacks, these should form a very solid base for the upper floor, much sturdier than…

As expected due to the rain, Thursday was a washout, as was Friday.
Then, today, this happened:

Ground floor frames are up! (Mostly, still a bit of finishing off to do).

The slab ended up turning out quite well - good enough for a polished concrete finish, despite not being spec'd as such (we're going with tiles, mostly for aesthetic reasons).

Note the very expensive and high-tech wet-curing system that is very definitely not jury-rigged from various miscellaneous garden watering components :wink:

Floor structure - trusses (Posistrut) vs I-joist (hyJOIST)?

Probably a long shot, but thought I'd ask anyway:
Does anyone have any data/experience re performance in minimising floor deflection/bounce/vibration trusses (e.g. PosiStrut) vs I-joists (e.g. hyJOIST)?
In my specific case, flooring…

Looking good!
Too bad about the extra drainage needed for the spring, but on the positive side, you might have a nice water source there that you can use for gardening.
