Can you knock down your half of your semi detached property?

In most cases, you cannot knock down your half of a semi-detached property without the consent of your neighbor, as it may affect the structural integrity of the shared wall. Additionally, local building regulations and zoning laws often require permits for such alterations. It's essential to consult with local authorities and potentially engage with your neighbor to discuss any planned renovations. Always consider hiring a qualified architect or contractor to navigate the legal and structural implications.
