Townhouse (Great Britain)
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.
Spencer House in St James's, London, one of the last surviving true townhouses still owned by the noble family that built it, the Spencers, although it is now generally leased out commercially. The corresponding country house is Althorp in Northamptonshire.
