Which of the following is NOT a common party wall problem?

In the context of party wall issues, the primary concerns typically involve structural and functional integrity that can affect both units sharing a wall. Common party wall problems include situations where there are unforeseen gaps or discontinuities that can lead to sound transmission, moisture intrusion, or heat loss.

Construction materials like wood can be very common in residential construction, particularly in homes with party walls. While the choice of materials might influence the sound insulation and moisture control, the use of wood itself is not inherently a problem related to party walls. Therefore, it does not represent a typical issue that would arise specifically in the context of party walls.

On the other hand, issues like ice dams, which can occur due to poor insulation or ventilation and affect the roof line, or discontinuity in materials leading to gaps that allow for noise and moisture to travel, are directly connected to how well a party wall functions. Similarly, incompleteness in attics can indicate a lack of proper construction practices affecting the shared wall space. Hence, while these issues directly relate to the use and function of party walls, the option regarding wood as a construction material does not align with common party wall problems.
