A cool mistress and a steaming spouse does not feel like a great solution - although on reflection....

Just Paint the post the same colour as the render.

Mars bars as well I suspect!

Pull up / pull down will depend on the internals of the shelly. I haven't looked but I would expect some sort of opto isolation on the input for safety so could be leaky either way a dry contact will be active in someway or other on the inside!

Very interesting link.

Respect..... I looked at DIY WuFi and decided the learning curve was not worth the candle so paid for a pro to do it.

How are you dealing with the dust getting into the system.

Our self install is running at about £3.5K for bits, 150m2 2 bed home. Not switched it on yet and I am sure I have made it more complicated than it needs to be, will see how it goes in a couple of months when we turn it on.

If you have a sloped base you have transformed the loading from all directly down to somewhat (mostly in this instance) down and somewhat (not much - but still some) along the beam in the direction of the slope. So if you load the beam it will somewhat want to slide down the slope and push the wall / support the other end - beware....

yes - sorry, I meant what brand of trial version did you use.

Which version did you use?

great - keep on keeping on, the challenges will keep coming but you will see the end eventually.

We used Helifix inskew's stainless, they did the loading calcs and gave us a fixing schedule, dead easy to drive in with the SDS fitting good for pitched and vertical cladding - not expensive really. https://helifix.co.uk/products/warm-roof-fixings/inskew/

I forgot to add that not only would you save the waste water charge but also the fresh water charge so that adds up to £6.50 m3. That means that if you had 2 IBCs buried in the garden you would have £13 of liquid assets

Correct. Sewage assumed to be the same m3 as mains water bought. I don't know if that applies everywhere. True for Southern at least so assume the same everywhere. I have put in the parallel plumbing to the three loos in case we choose to go that way.

What I was thinking of was deleting the sewage treatment cost that is worked out as a proportion of the metered water. If I use grey water for the cisterns then the mains take will reduce and that's worth £3.70 per cubic meter of mains water not used.

Given discussion elsewhere and cost it struck me that a bore hole might be a cheap option for grey water delivery to your toilets etc than using storage where you need a big hole. A bore hole would perhaps deliver water that needed no treatment for such a purpose. Anybody any experience of doing this?

OK- rather hijacked this thread hear so started a new topic.

Do you need an extraction licence or some such?

Congratulations and enjoy the onward journey.

+1 to that. We built our garden room as a model for the house as timber frame using the same techniques - I Joist etc, but with thinner insulation. However if you are going brick / block for the extension then perhaps raft is not such a good choice.

The chap we used was from Umbay. Energy & Design Services info@umbay.co.uk. The final invoice was only a couple of hundred.

I will dig it out - I think I mentioned it here probably 6+ years ago.

I worked my way through this on our build and in the end I chose to get a professional to do the calcs for me and then give me a full report which is a sort of guarantee that the design is sound. The cost was less than the licence as I recall and de-risked our journey through that bit of the design.

Tell him after the scaffold is moved?
