How long do have to complain about an extension built by a neighbour

generally before it is built and signed off by building /planning, this does not stop you takung legal action if it infringes on your property but you might have a few questiobns as to why you never raised these issues as it was being built and has taken 5yrs to come to the assumtion it been built on your property.

Hi , It very simple you need to contact the local council who gave planning permission and ask for which officer signed of the plans. You find that a lot of the time the council officer’s attend the property before work commences and then if they think the builder is competent they won’t return just ask for pictures of the progress. You have to,as a builder follow the plans otherwise you run the risk of having to re do it all again to comply . Once you inform the council that these boundaries have not been adhered to and the plans not followed they will make your Neigbour make the adjustments I hope this helps you

In the first instance it may be worth instructing a specialist boundary surveyor to carry out an inspection in order to clarify whether the neighbouring property is actually on your land and, if so, to what extent. This would be particularly relevant if there are no clear boundary markers. If it is confirmed that the property has been constructed over part of your land, then this is a trespass which offers a number of remedies. An injunction may be sought to require the adjoining owner to remove the relevant part of the building, or damages may be payable in order to compensate you for any loss suffered. Such a decision will be at the discretion of the court. Another option would be to enter into a negotiation with the adjoining owner to sell the land to them. It may also be necessary to consider whether the adjoining owner’s building interferes with your ability to use your property, such as access to light, rights of way or your own ability to develop the property, as there could also be a claim in interference.
