Dundee's residential core is substantially sandstone tenement construction, with shared closes, timber floors spanning between solid masonry walls, and structural arrangements that were rarely recorded. Alterations in a tenement affect neighbours as well as the owner, because the walls and floors are frequently shared or interdependent.
Sandstone weathers, and locally it can be soft. Bearing details that would be adequate in harder stone need checking, and previous repointing or repair sometimes conceals more significant deterioration behind it.
