Villa Extensions · Shared Walls
Do I need my neighbour's consent to build next to a shared wall?
Yes. Building next to a shared wall needs your neighbour's consent, plus the developer NOC and building permit.
The short answer
Yes. Building against or next to a shared wall, for example in a townhouse or semi-detached villa, needs your neighbour's consent, as well as the developer NOC and the building permit. The design must not overload or damage the shared wall, so the structural calculations check it. Structural Solutions designs the works, prepares the calculations and applies once consent is in place.
