What type of house is joined to another house on one side only?

A semi-detached house is characterized by being joined to another house only on one side, with its other side standing alone, providing a degree of separation from neighboring homes. This design allows for shared walls with a neighboring property while maintaining some level of privacy and space on the opposite side. This layout is particularly common in residential areas where land use efficiency is a priority, as it maximizes housing availability while offering a balance between community living and individual home space. The semi-detached configuration is an attractive option for many households, providing easier access to light and potentially larger backyards compared to terraced houses, which are connected on both sides, and detached houses, which stand alone without any shared walls.
