The Town House (or Townhouse Studios) was a recording and mastering studio complex in West London, built by Richard Branson and Ian Cooper in late 1978 as part of the Virgin Studios Group (along with The Manor).
The Goldhawk building included 3 recording studios (studio 1, studio 2 and studio 4, the latter was built later) and 2 cutting rooms (equipped with Neumann VMS 80 Lathes, SX74 cutter heads and SAL74 Drive Amplifiers). In 1985 Townhouse added a VMS 82 for Direct Metal Mastering (DMM).

Lacquer cuts can be identified by "TOWNHOUSE" or "TOWN HOUSE" stamped or occasionally etched into the runouts.
DMM masterings can be identified by "TOWNHOUSE DMM" or "TOWNHOUSE D.M.M." etched into runouts and occasionally just "TOWNHOUSE" etched combined with a stamped "D“ (plated or pressed by EMI Records) in the runouts.
Lacquer cuts for PRS Ltd. can be identified by ▽E TH (between February 1979 and ~1983), and by ▽420 H (between ~1983 and mid 1988).
Lacquer cuts for Lyntone Recording Ltd. can be identified by a trailing ITH.
