Non-standard construction
Steel shows at the eaves of a system-built house and nowhere else. What of the stanchions stays hidden?
The stanchions inside the walls stay hidden. Steel visible only at the eaves of a system-built house is the frame where it meets the roof edge. It does not show the uprights, their bases, any coating, or the fixings buried behind cladding. The survey recorded the exposed steel it could see. It has not opened the wall and has not decided that hidden stanchions are sound because the eaves look tidy. Corrosion lower down would not show in that glance.

What is the fuller explanation?
System-built houses often wrap the steel frame so that only a small length appears at the roof junction. Corrosion, a failed base, or a poor connection can sit behind render or panels and still leave the eaves looking freshly painted. Seeing one clean edge is not a survey of the whole stanchion. The report should keep that limit in view. Nothing in a glance along the gutter line measures the steel you cannot reach.
Ask the solicitor whether frame reports, repair guarantees or original system details are in the papers. Those documents are not created by this inspection. A specialist in non-standard housing can open cladding where that is agreed, which this visit did not do. Do not tell a lender the frame was examined throughout because steel showed at the eaves. The hidden lengths remain undescribed. Do not fill the gap with a system name taken from sales particulars.
What should you ask your surveyor?
- Was steel recorded only where it shows at the eaves?
- Were the stanchion bases and fixings left behind the cladding?
- Are any frame reports held outside this inspection?
What are the typical next steps?
- Treat eaves steel as the visible edge, not the whole frame.
- Ask the solicitor for system details or earlier frame reports.
- Do not describe hidden stanchions as examined on this visit.
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
Does paint on the visible steel describe the hidden lengths?
No. Paint or a clean surface at the eaves describes only that short visible piece. Coating behind cladding can be different, missing, or broken at the base. The survey did not strip finishes to compare them. Keep the painted edge as a local note, not as a verdict on the stanchions inside the wall.
Can the house name alone identify every hidden member?
No. A system name, even where it is known, is not a view of these stanchions. Manuals describe a type. They do not show whether this frame has been altered, cut or repaired. The survey recorded steel at the eaves. It has not matched every hidden member to a drawing.
