Do I need my neighbours’ permission for an extension?

However, there’s a difference between having a tiff and being able to transform your house the way you want without having to obtain your neighbour’s approval.

  • In the event whereby your new extension is blocking their view or providing an unwanted shade on their property. Here, they have a legitimate reason to protest as no one would want their once sunny garden suddenly covered or plummet into shade.

  • If it’s a major project and going to take a lot of weeks before completion. The noise generated, especially when your neighbours are enjoying your summer holidays or weekends, can make their gardens not as relaxing as it used to be.
