ᐅ Terrace with privacy screen as a visual barrier to the neighbor

Hello everyone,
I have a question. We live in an end unit of a row house and are currently planning the terrace for our garden.
Our neighbor’s house is directly adjacent to ours. Since the neighbors will only move in later in the year, we want to get started now.
We have already agreed to install a partition wall between our terraces, practically right on the boundary line. The fence will be installed the same way. The posts for the fence will be placed between the edging stones.
I have a question about the order of the work.
If I build the terrace first, can the partition wall still be added later when the time comes? Or should the partition wall be installed first?
What does the final result look like, and how exactly is the partition wall installed? Is it done similarly to the fence?

Thanks

It depends on the type of partition wall you want and its construction. If you want the typical wooden elements on galvanized posts, first set the posts in concrete and then pave around them.
