Arundel House was a London town-house located between the Strand and the River Thames, near the Church of St Clement Danes.

In British usage, the term townhouse originally referred to the opulent town or city residence of a member of the nobility or gentry, as opposed to their country seat, generally known as a country house or, colloquially, for the larger ones, stately home. The grandest of the London townhouses were stand-alone buildings, but many were terraced buildings.
