Townhouse from WikiPedia:

Historically in the United Kingdom, Ireland and in many other countries, a townhouse (or a "house in town") was a residence of a peer or member of the aristocracy in the capital or major city. Most such figures owned one or more country houses in which they lived for much of the year. During the social season (when major balls and drawing rooms took place), and when parliament was in session, peers and the servants moved to live in their townhouse in the capital.

In North America and Australia, the term townhouse is also commonly used to refer to what is known as terraced housing in Britain.

In the United Kingdom and Ireland most townhouses were terraced. Only a small minority of them, generally the largest, were detached, but even aristocrats whose country houses had grounds of hundreds or thousands of acres, often lived in terraced houses in town.
