Expansion joint in clinker, yes or no

Dear fellow campaigners and experts,

I need your advice, opinion, or experience.
Tomorrow our brickwork will be laid, and we now have to decide whether we should have it built with or without an expansion joint?
Our developer, whom I hold in high regard and whom I also attribute the necessary experience, says we don’t need one but wants to leave the decision to us! As laymen, we now face the choice! What do you say?
For your information, the house measures 10.20 x 9 meters and our brick is an ABC hamburger coal-fired brick. On the building plot, there were previously buildings and trees!
I look forward to constructive answers
Best regards symen

what do you say?

That you should continue to trust your BU because he is right

Hi construction expert, thanks for your quick reply! As I said, I do trust our BU, but I have received so many different opinions from my surroundings that we are a bit unsettled.

.... but I have received so many different opinions from my environment that we are a bit unsettled.

Free yourself from the idea that answers from relatives/friends might help you; mostly they just confuse you. In addition, most well-meaning advice is not based on expertise. Ask them whether they can guarantee the feasibility of their suggestions. Then they quickly backtrack. And – ultimately, you chose your BU for a good reason, so continue to leave the execution to it! For gut feeling – and awareness of good advice – you can always consult an external expert. Rhineland greetings

Expansion joints are urgently necessary according to the brick manufacturer Olfry and are even required according to DIN 1053-1. The house must be able to settle, and without joints, there is a risk that the bricks will crack...

Then your supplier should read it carefully again

Quickly:

"Brick cladding shells have been carried out for decades largely without vertical expansion joints in smaller single-family and two-family houses with floor plan dimensions of about 10 to 12 m. Therefore, it is a proven construction technique which also meets the requirements of the masonry standard DIN 1053-1. A commentary on DIN 1053-1 points out the following:

'Experience shows that, for example, in smaller building floor plans of single-family houses with brick cladding shells and gable widths or lengths of 10 to 12 m, it is not necessary to provide special expansion joints."
