Recommendation for terrace partition for a semi-detached house wanted

Hello everyone, since we have now made some progress with the terrace, it is now time to plan the partition wall.
Briefly, we have decided on a Betonplus slab from Kann in wood look. This is to be framed all around.

The landscaping contractor would now like to install a terrace partition immediately. According to him, this would be difficult later because the terraces (semi-detached house) are framed, and afterwards, the frame would have to be destroyed again to anchor the partition wall accordingly.
Since the prices for the partition wall from the landscaping contractor are really steep, we would like to do it ourselves later in consultation with the neighbor. Therefore, here are my questions:

1. Is it really that "difficult" to make the partition wall later when the terrace is already in place? Of course, I would only reluctantly want to "ruin" the landscaping contractor’s work.

2. What kind of partition wall can you recommend? Ultimately, we only have one neighbor, as this is a corner lot.
We had been looking at something made of WPC. But of course, in terms of "sound insulation," it is certainly not the best solution.
On the other hand, a wall would heat up significantly in summer.
We are therefore somewhat clueless and hope for your tips.
What goes well with a terrace in wood look?

I would like to say many thanks in advance.

There are so-called concrete fences with various surface layouts. From plain planks to stone or wood look. We will use something like this for our semi-detached house. You can quickly construct the partition wall yourself and individual layouts can be used on each side.

The Gala is not wrong. The curbstones or boundaries are set in concrete. Knocking them out afterward to dig foundations is no fun. It is doable, of course, but if you agree now, it makes things easier and probably also nicer. If you have to open it up again, you won’t get it 100% right anymore. Search for Sichtschutz Lärche Rhombus. I wouldn’t put plastic there, nor a wall. Some wind permeability is also very valuable in summer.

Both sound not bad, does anyone still have another suggestion

I am facing the same question. We and our neighbors do not want the glass partition wall that is being installed by the developer. We both want the developer to do nothing there and for us to build something ourselves together. What do you think about the stones that are hollow inside, which can then be filled with sand, soil, or gravel so that they stand stable? The concrete fences are definitely also very interesting. Are there any other alternatives?

Have the garden landscaper Hülsen concrete in for fastening a partition wall. That way, you save time. Presumably, you also want to coordinate with your neighbor, right?
