What's the difference between a'semi-detached house' and a 'detached house'?
assistant
A semi-detached house is one in which two houses are connected by a common wall, typically with a shared driveway or walkway. The two houses may be of different sizes, but they are not separated by any other walls. A detached house is one that is completely separate from any other building, either by being on its own lot or having access to a common area such as a street.
