New extension when we already share one with neighbour
Hi, we are interested in building a bigger extension on our terraced house. But we already share a small pitched roof extension with our neighbour which contains mirroring kitchen and bathroom, we think it dates back to 90s.
Ideally we'd open out a lot more with a bigger open plan kitchen and family room extension. We certainly have the space but can't see how it could be done without demolishing our half of the existing structure.
Can this be done, and would we still have to build out our new extension from neighbour in order not to leave them with half a structure?
Thanks
Chris
