Wall thickness, sound and position can offer clues, but cannot establish a wall’s structural role. Have the available records and the actual building assessed before deciding on removal.
Start with records
Collect original plans, sections and records of later alterations. Mark the wall you want to change. A sales floor plan can explain the layout but may not distinguish structural elements. Compare the documents with the present home and flag differences rather than filling gaps with assumptions.
Look at the wider structure
The assessment considers floors, walls and sometimes the roof above, as well as supports below. A wall may contribute to stability as well as carrying vertical loads. Its function cannot be determined reliably by knocking on it or comparing it with one in a neighbouring house.
Prepare a useful first enquiry
Provide photographs of both sides of the wall, adjoining rooms and the position on a plan. Describe the property type, floor, approximate age and previous work. Do not open finishes or remove pieces of a possibly structural wall just to obtain a better photograph.
Turn uncertainty into a clear brief
Ask the engineer which parts are known and what additional information is required. A site visit or further investigation may be needed. Once the role of the wall is understood, the engineer can assess the proposed opening and the associated supports and connections.
Frequently asked questions
Does a thick wall always carry loads?
Thickness alone is not proof. Material, position, construction above and the wall’s role in stability all need to be considered.
Is a hollow sound proof that removal is safe?
No. Sound is not a reliable structural assessment. Keep the wall intact until its role has been established.
