Do you live in a house built in the 1960s–90s?
- From the outside, looks like a normal foundation but inside, the bottom part of the wooden frame is at the same level with the ground, or even below it.
- The false stem wall structure was used from the 1960s up to the mid- 1990s.
- Typical houses where false stem walls were used: a brick-clad house with a flat roof or ridged roof with a shallow slope, no substantial height difference between the ground and the floor.
- Also in houses with concrete block foundations built in the 1980s and 90s.
