Non-standard construction
The neighbour calls this a Cornish unit. Has the survey adopted that name from the street, or only from what it could see?
The survey has not adopted the neighbour's name from the street. A Cornish unit is a named concrete system, and that label belongs only where the construction seen on site supports it. This inspection records what it could see. A call from next door is not that seeing. If the panels or the frame were not visible, the survey has not promoted the nickname into an identification. The street name stays hearsay. The report should not be read as having adopted it.

What is the fuller explanation?
Former council houses on one road can be ordinary brick, a concrete system, or a mix after later alterations. Neighbours often use one local name for all of them. A survey names a system only from a basis it can see: panels, a frame, thickness, sometimes the estate pattern in front of it. A verbal label does not supply that basis. If the type is uncertain, it should stay uncertain. Second-hand naming is not identification.
Ask the solicitor not to write Cornish unit into the forms unless the survey, or another proper source, has identified it from the building. A lender may have rules for named concrete systems, and those rules are the lender's. Do not trigger them with a neighbour's word. If the type is uncertain, say so. The survey has not certified a system it only heard about in the street.
What should you ask your surveyor?
- What construction did the survey actually describe from the building?
- Were panels or a frame visible, or only a rendered face?
- Has the report said the type is uncertain?
What are the typical next steps?
- Use the survey's own description of what it could see.
- Do not put the neighbour's label into the legal forms.
- Ask the lender only about a system the inspection has identified.
Costs vary with the building and with who you instruct. Where this page does not cite a published figure, ask the surveyor, a relevant specialist, or your solicitor for a written quote. Do not treat a forum average as the price.
Also asked about this
Is every former council house on the street the same system?
No. A former landlord is not a method of building. Houses on one street can be ordinary masonry or a named system, and later cladding can hide the difference. The survey has not adopted a street name for this house. Each building is identified from what can be seen there. The neighbour's label is not proof along the row.
Does the neighbour's label decide what a lender will accept?
No. A lender applies its own rules to a construction that has been identified. A neighbour's call is not that identification, and the survey has not adopted it. Do not tell the lender this is a Cornish unit because it was said in the street. If the type is still uncertain, pass on the uncertainty.
