Interwar (1919–1944)
What a home of this era typically means
  • Cavity walls begin to appear, but many of this era are unfilled — worth checking whether they’ve been insulated.
  • Foundations are deeper than Victorian but still shallow by modern standards; clay-heave subsidence is the classic risk.
