Is it possible to install external horizontal cross-insulation outside the edge beam?

[Martin Lj]

I have drawn the following image for my extension. My current house is on a crawl space foundation where the wall "hangs" ~10 cm outside the foundation/edge beam. I thought the extension should look the same to match the existing house.

Now, in the drawing, I have positioned the vertical 45*45 beam with external cross-insulation outside the edge beam, which results in 45 (beam) + 28 (batten) + 21 (panel) + 21 (cover panel) = 115mm hanging outside the foundation, is that ok?

The other option is, of course, to move the entire wall 45mm inwards. But then I would have 9cm less interior space.

There is no problem at all. Little weight on that part, and the load-bearing is the framework that transfers the large load, which rests on the foundation wall.

Do not forget vertical ventilation battens of at least 10 mm behind your horizontal nail battens.

And don't forget the mouse band at the bottom:


But I don't see a vertical 45x45 rule in the picture.
