I’ll pass your comments onto the author.

I’d say it doesn’t cross their minds to put a grid on.

Why are you insulating the garage walls? Is it heated?

I think there are bigger thermal bridges than the steel post……just saying!

Post your SAP so we can take a look. I’m very surprised that a timber frame is failing the SAP. I would also assume that the junction calculations are taken from standard details rather than specific construction drawings.

I am quite happy to do a design for you…..please let me know if I can help…..

All well thanks…..SSDD……

Need ICs at changes in direction Gus……

Who in their right mind designs structural support over a drain?🙈……the extension isn’t really worth doing!

I would have done a design for free!

Why start now!

Just send in your SAP.

The condensate collection pipe should be insulated inside and outside the unheated space and should terminate to a suitable foul drain - not a rainwater downpipe. Failing this it can be connected to a limestone filled sump > 1.0m from the foundations. If the boiler is inside an attached garage/space a CO detector/alarm should be fitted. Also you may need to have a Building Control Application made for the works.
