I would do it the way you planned as well. The front house facing the street as sound protection and build new behind it. The risk of construction on the south side exists – but I consider it not urgent. At least, from the pictures, no access road for potential further construction in the neighbor's rear area can be seen. Also, not everyone wants to build immediately.
I would include soundproofing in the entire planning. Also for terrace, windows, room layout, etc.
It is a dense development and the plots are small. But that seems typical for the area and is okay. Those who want more have to move to the countryside.
Budget is probably unrealistic for 2.5 floors + demolition. But others know better. Maybe it's better to sell the front house?
Hi kaho674, thanks also for your feedback.
Unfortunately, the house already has an access road on the south side (courtyard passage on the ground floor). I also think the risk isn’t too high. And even if at some point an extension is built onto our house, we can live with that.
The budget is of course more of a wish, since I want to pay off the house as quickly as possible. Therefore, selling the front house is not necessary. But of course, we can still consider it.
The 13 euros are enough for debt service and maintenance, not much more.
Would not take tenants
We do not have an S-Bahn, mainly rowdy youths, currently one is holding back – was firmly asked to keep quiet.
Building with a ventilation system and taking soundproofing into account
I think we will keep the option of using the front area with the old house open and decide once we have built and moved into the new house. Perhaps interests will then lie elsewhere.
Does anyone else see potential advantages of building with setback from the boundary that I haven't considered?
Best regards and Happy New Year
