Fence construction at a semi-detached house, if the neighbor builds later?

Hello everyone,
The following situation:
Semi-detached houses: we are currently already building, the neighbor only in 1-3 years. If we now fence our garden towards his future garden or also build the terrace enclosure towards his future terrace (on our property), is this a problem when he builds later due to possible excavation for a basement or otherwise, or is this rather uncritical?
Thank you

well, you have a foundation for the fence /( Terrace protection ( possibly). That could be affected.

Towards a page that will surely change soon, I would only enclose provisionally, i.e. at least not lay the fence foundation permanently yet.

If you build without a basement and he does with one, the boundary fence will be the smallest problem.

I maintain that for an uncoordinated semi-detached house construction, one must be crazy.

We are definitely building with a garden..unknown at the neighbor...

I maintain that you have to be crazy to undertake an uncoordinated semi-detached house construction.

Why? What do you mean by that? Thanks in advance for your answers

Your house will be affected, the foundation slab will be undermined, etc. Cracks may occur, etc. You will have dirt and more directly in front of the house for another year after you have finished.
