We have nice decent neighbours and we get on ok. I am also very mindful that they can do whatever they want to their property without our permission, and a lot of improvements/ adaptions are led by fashions/trends. But everything we do, they do. It’s just a long list of mostly minor things. Same fences, same outdoor lights, same garden furniture, same drive block paving. We had our kitchen roof changed to sky lights.. they did the following year. Changed our patio doors to bifolds, so did they. We had a big pergola built… now so have they. It’s become a bit of a family joke tbh. Would it irritate you?
