Gone West

I had a similar problem at my last self build. I cut out the section of strongback, where I needed access and replaced it with a noggin top and bottom between the metal web joist flanges.

I just screw a bit of OSB in the hole and finish it the next day, and don't do it in mid-winter.

I have used Modern UPVC Windows for both windows and doors and not had any problems. I think they are good value for product and service. I did fit them myself though. https://www.modernupvcwindows.co.uk/

From the links I put up and from the roofers who put the Sika membrane on my extension. With all due respect, I don't think how it feels when walking on it, determines how it's classed.

A roof is classed as a flat roof up to 10 degrees. I am currently working on a small area of roof on my place and although it is 11 degrees, I'm treating it as a flat roof, for covering material. https://ikogroup.co.uk/news-advice/what-is-flat-roof-compared-to-pitched-roof/ https://en.wikipedia.org/wiki/Flat_roof

So for pre 2024 installations is it just a 'nice to have' retrofit?

Our installation was done in 2012 and the RCD certainly isn't bi-directional.

We had 185L heated by EASHP to 45C and the 'two of us' never ran out of DHW in the three years we lived there.

No, the team laying the concrete asked where they could put the excess and washout, and we had bulk bags lying around. There wasn't that much really.

We just used bulk bags, which all the excess concrete and washout went into. Excess water drained out of the bottom.

We fitted Kidde wireless alarms and because of the vaulted ceiling on the landing we wall mounted the alarm. It was nine years ago now but there were no problems with sign off.

You know I've always trusted you 🙄.

I wouldn't argue with Claude!!
