Gone West

I didn't explain myself very well. They put up the end frames and a couple of frames in the middle using muscle, braced them, and then used a crane to drop in the intermediate frames. We had some dormers, so some of the frames were odd shapes.

Ours started off like that, then the infill frames were craned in. IIRC the SE said the limitations of this system is that the roof angles can't be shallow.

I've never heard of my type of house construction being called space frame. I always called it a timber I-beam portal frame. IIRC the idea was later used by a company called PH15. A space frame to me is the type of frame used in old, light weight, racing car construction, but I could easily be wrong.

I dismantled our old 1920s, stick built, timber frame bungalow after we had moved into the new build. Building Control weren't interested, it took us a couple of weeks to do it, after we had had the asbestos removed. We recycled virtually all of it, and it only cost us the price of hiring a concrete crusher for a while. We also took down a couple of single garages, one block built and the other a concrete panel construction. A nearby similar bungalow to ours was knocked down by a local farmer using a telehandler and removed to be burnt at the farm. It took them less than a morning, but I preferred our way of doing it.

I've heard that before, but not been able to find the document. Do you have a link you could share?

Are corrugated stainless steel flexi connectors a better type, or are there any downsides? https://ridgelinetubes.com/flexis/

Same here with large trees. Doesn't make any difference as long as you're not under trees all the time.

Get a Kress, good German engineering.

I was told, if using screws, use partially threaded screws with solid stem at the top.

I've only ever seen physical templates which were easy to check. I wouldn't want to rely on a drawing.

When I fitted our undermounted sinks, I used G clips to fix them. http://www.gclip.co.uk/Home.html All that should have been taken care of when it was templated. If there is to be an upstand then minor gaps are covered.

It's an achievement having two in agreement.

Where does it all end??

Over the years we've had several of the Harvey block salt softeners and a Monarch and they all seemed to work without problems. The last one I had to buy for the new build was a Crown, but that was nine years ago. https://scalefreehome.com/harvey-vs-monarch-water-softener-uk/
