Can you Extend an Extension Without Knocking Down the Original?

Postby digitalmoe » Tue Jan 16, 2018 5:17 pm

Hello...this is my first post.

I have a end terrace house which currently has a 3 meter rear extension...I have contacted the local authority and asked them if I would be able to extend it another 3 meters to make it a full 6 meter rear extension...the LA advised I could and this would fall into permitted development if carried out by March (or so) 2019.

What I would like to know it possible to extend an existing extension without demolishing it and starting again? ...I just want to make the the rear extension longer...currently it has a flat roof and I would prefer to have either a pitched roof with skylights with a flat roof with lanterns.

...would it be the case of knocking down the rear wall/windows and just extending on from the current structure? ...any help would be appreciated so I can plan for the build and factor in the costs etc.

Property is in London.

Thank you.

Yes, it is possible to extend like you said but it would be advisable to take professional building contractor's help or an architect. As for building extensions, you will need a party wall agreement if you have a neighbouring wall attached to your property.
