Party walls and boundaries
A steel beam disappears into the party wall and the neighbour's side was not opened. Can the survey say the bearing on that side is sound?
No. The survey cannot say the bearing on the neighbour’s side is sound. A steel beam disappears into the party wall, and the neighbour’s side was not opened. The bearing on that side is the part of the beam the inspection did not see: how much steel is in the wall, what it sits on, and whether the neighbour’s masonry is adequate. Soundness is a conclusion about that hidden end. The survey has no view of it, so it cannot give the conclusion. What it can say is that the beam enters the party wall on this side.

What is the fuller explanation?
A party wall is shared. Opening the neighbour’s face is not a ordinary part of a home survey, and it was not done. GOV.UK describes party-wall procedures for certain work, which are notices and agreements, not a sentence in a condition report. This visit did not serve those notices and did not inspect from next door. The beam may be properly seated. It may be pushed into a chase that does not support it. Those remain possibilities. Neither is a finding.
Ask the solicitor whether any party-wall award or beam design describes the bearing, and do not ask the survey to guess across the wall. If the end must be seen, that is an access question with the neighbour, then an engineer’s look, not a revision of this report. The inspection has not called the far bearing sound. It has not called it failed. It was not opened.
What should you ask your surveyor?
- How far could you follow the beam before it disappeared into the party wall?
- Was the neighbour’s side opened, or was that bearing unseen?
- Did you refrain from calling the far bearing sound?
What are the typical next steps?
- Do not read the beam as sound on the neighbour’s side.
- Ask the solicitor for any party-wall award or beam design.
- Arrange access and an engineer if that end has to be seen.

Also asked about this
If this side shows a padstone, does the other side have one?
Not as a finding. A padstone on this side, if one was visible, describes this side. The beam still disappears into the party wall, and the neighbour’s side was not opened. The survey cannot copy a bearing across a wall it did not enter. The far end stays unverified.
Can the neighbour’s surveyor be assumed to have checked it?
No assumption of that kind is in the report. The home survey did not open the neighbour’s side and did not read a neighbour’s report. GOV.UK’s party-wall process is separate, and it was not carried out on this visit. The bearing on that side has not been called sound.
