Will My House Lose Value??

Brightspark98

I currently live in a semi-detached house and next door is planning an extension which would adjoin my house creating a link. What impact would this have on the value of my property?

Any help or advice greatly appreciated.

I am not an expert, but they cannot join your property without you agreeing to it (& there would have to be a party wall agreement I believe).

Whilst you haven't specified the nature of the join, it sounds like it would turn your semi into a terrace and if so I can't see it is going to do anything other than devalue your house.

Has your house been extended to the boundary with them?

Is the extension to the house that you are already attached to (being a semi-detached) or the house the other side that isn't currently attached?

Yes my house has been extended to the boundary around 15 years ago and the extension is to the house that is currently not attached.
Thanks for the replies so far.

i doubt they wll join it to your house, but will go to the boundary as you did yours, might get a newspaper inbetween your houses afterwards

As others have said, they cannot physically join without your consent.

Have you actually seen the plans?

Has planning permission been granted? Since their extension is up to the boundary, this would not constitute 'Permitted Development' so they will need to apply for Planning Permission.

Which you can object to.

Where does yout own extension go to? Exactly the centre of the boundary? Usually the 'footings' (foundations) are wider than the wall. The footings might extend to the boundary but the wall itself would be above the centre of the (wider) footings, so would be on YOUR side of the boundary.

Their wall should be similar, leaving a gap between your respective walls, the gap being on the boundary line.

Of course, if you and your neighbour agree, you could share a single wall and turn your houses into terraced.

Yes, it would lose value!

Some councils have a policy to oppose semis being joined up into terraces by extensions. Although the one I'm thinking of, it doesn't seem to stop it happening.

So yours is extends to the boundary but you don't want them to do the same?

They can't join without agreement, but having tiny gap is not a great idea either as any dirt, bits of cement will bridge and can let damp cross.
