What do steel & timber frame drawings cost?
Honest ranges for the DRAWING / detailing work only - kept separate from the structural engineer's calculations and from steel supply/fabrication, which are billed by others.
| Work | Typical range |
|---|---|
| Single beam / knock-through detailing (from calcs) | £150 - £450 |
| Extension steelwork drawing set (from calcs) | £300 - £900 |
| Garden room / office construction drawings | £400 - £1,200 |
| Mezzanine floor fabrication drawings | £500 - £2,000 |
| Portal / agricultural frame fabrication drawings | £800 - £3,000+ |
| Steel staircase detailing | £300 - £900 |
For comparison and not charged by me: a structural engineer's calcs typically run £400-£2,000, and steel supply/fabrication is separate again. Every quote is fixed up front.
Structural sizing, spans and load calculations must be carried out by a qualified structural engineer. These pages help you plan the drawings you need - they are information only and are not structural engineering advice.
