I know in the UK, they do a discovery thing when you go to buy a house, but I am unsure if they do the same here.
Looking at a place near me, but it has an empty plot next to it, and fields close by and well I don’t really want to invest in a house next to or adjacent to a building site.
Could ask the commune I guess? Anyone any other thoughts… I am sure you cannot trust the estate agent to tell you the truth anything…
Your local Gemeinde (council) should have an online map indicating various zones. Their website should have planning applications, otherwise a visit to them will find out what’s going on.
Building sites don’t last forever. While the Swiss don’t throw up houses in 6 weeks like the UK, 18 months to 2 years will be long enough…
