Age and type of house
The lounge chimney breast is gone and the bedroom above still has its breast. What support in the floor void was not seen?
The support in the floor void was not seen. The lounge chimney breast is gone and the bedroom above still has its breast, so something in the floor zone ought to be carrying what remains. Gallows brackets, a beam, or another designed support would sit in that void, and the survey did not see them. The loft is not the floor void. Looking between the ceiling joists of the roof space does not open the floor under the bedroom breast. The inspection recorded a missing lower breast and a remaining upper one. It did not confirm the support.

What is the fuller explanation?
Removing a chimney breast is a structural alteration. Approved Document A is the building-regulations guidance on structure, and a home survey does not apply it as a certificate and does not issue one. The practical gap here is simpler: the member that should pick up the breast was in a void that stayed closed. The survey did not lift floorboards and did not find ends of steel in the lounge ceiling. Absence from the loft is not absence of a bracket, and it is not proof a bracket exists.
Ask the solicitor for any building-regulations approval or structural design for the removed breast, and if those papers do not show a support you can believe, ask an engineer what opening-up is needed. Do not assume the bedroom breast is carried because the house is still standing. The survey has not seen the support in the floor void, and it has not said the alteration was approved.
What should you ask your surveyor?
- What of the floor void under the remaining breast did you actually see?
- Were gallows brackets, a beam, or no support at all in view?
- Which papers for the removed lounge breast were missing from the pack?
What are the typical next steps?
- Treat the floor-void support as unseen, not as present or absent.
- Ask the solicitor for the design or building-regulations approval.
- Ask an engineer what must be opened if those papers do not settle it.

Also asked about this
If the bedroom floor feels firm, is the breast supported?
A firm floor is how the boards felt underfoot. It is not a view of the void, and the survey did not see gallows brackets or a beam there. Feel is not the support. The remaining breast may be carried, or it may not. The inspection has not decided, because the support was not seen.
Does a steel plate in the lounge ceiling prove the brackets?
Only if the survey could see that the plate is part of a support, and even then the bedroom side of the void may still be undescribed. The finding on this visit is that the support in the floor void was not seen. A plate, if one exists, needs identifying. It does not, by itself, finish the question the closed void left open.
