It's interesting to me how few actually insulate this space.
Even the external walls in this section not insulated.
However acoustic batts sound better no idea if…

For DIY options CBUS does not even get close to the options available.
CBUS is just ridiculous on pricing.
Anyone should be able to do their own "programming" .
For any home automation…

the pipes should be installed whilst you have access to the bearers and joists.
Lagging all pipes if using radiators, although if in conditioned space maybe not.
What sort of pellet boiler…

Firstly I would not install electric coil in slab, too many people do not run it because of cost.
I have installed hydronic heating for small places including 40 sqm.
It would…

Insulate under the slab as well.
Just run some pex pipe in the slab.
The house needs heat with concrete floors.
Good luck

I'm sure a question asked allot.
If one is after dg thermally broken aluminium windows is there a rough m2 rate (supply only)?
Does one have a guide for the comfort glass…

You mentioned DIY
Have you looked at Arduino
Now that is DIY, cheap possibilities seem limitless.
Or other microcontrollers, Beaglebone Black
The idea of having the controller costing $50 is amazing.
Of course you…

Benex blocks were on the New inventors some time ago, the original factory closed (i think), ambitious business model.
But at $66m2 is a good price.
Lock Blocks by baine are mortarless…

Not exactly sure what you are asking.
The more thermal mass the better generally speaking with winter sun, assuming its insulated from outside.
So a reverse brick veneer house is better than…

C Bus is over priced.
Just run cat 5 or 6 cable to everywhere automation is required:
Light switches,
Power points
Blinds
Windows
Thermostats / sensors
Doors
Etc
Micro controllers are cheap and the possibilities are limitless.
Just run…

Earth covered homes have the potentially to be far more energy efficient.
Plenty of info on the web.

Helped a mate "remove" a pool.
We drained the pool straight into the storm water.
We cut the edge with concrete saw you could hire a guy to do this.

Short answer yes.
Daikin is rather common over seas.
A wood boiler is another possibility, especially the wood gasfication type.
Finally I would suggest solar boosted with a small heat pump as back…

When you xps which is extruded polystyrene and the best insulation other than aero gels.
Not sure how you place it in walls other than spray / injection.
Not sure if spray…

Sorry further read your posting.
If the house is already built this is just a reno then highly recommend under slab insulation.
50mm of EPS (expanded polystyrene) then 50mm of an almost…

If only looking at what the code is, then unless you live in alpine region unlikely to require under slab insulation.
However build with waffle pod slab and under slab insulation…

Hmm more pictures would be good.
From what I see only one down pipe is flowing into tank.
One overflow pipe coming from the tank.
The vertical pipe along the wall is the…

I guess you will turn off the valves (for the 50mm inlets) going into tank 4 before purging the first flush system?
Excellent diagram.

Update: Tankvacs have now been deleted from the design.
Camel tanks would not warranty if fitted as it would require cutting through the side wall of the tank.
Hmm good reason…

Bottom connecting tanks for balancing is fine but remember if all open one tank leaks all…

Great sketch, on putting words into pictures, I'm a bit slow with it all.
I have suggested to H20 to add some diagrams but he keeps saying he is no Michelangelo.

There would be many doors that would be classified in FZ.
I would think the doors used in fire stairways must be rated to the same.
Also door frame will have to…

Many thanks
Some excellent info.
I checked with the architect and he confirmed that is what he specified.
It really didn't have anything to do with me and he was in little mood…

Has anyone heard of double glazing with both sheets of glass low-e?
Its been specified in some plans?
I'm guessing they want no heat gain through the glass?
Any thoughts?

If major reno and gutting the place I too would seriously consider knock down.
The more questions you ask the more research you do it will pay dividends many times over.
Good…

Somebody's not sleeping, 1am post.
I would try if possible, leave existing flooring and lay some plastic then polystyrene on top then pipes then screed.
And bring the new extensions to that…

Thickness of waffle pods is determined by the engineer.
Depends on soil type and assessment.
In regards to removing the flooring structure, joists and filling with concrete.
Something I have seen a few…
