Frame Drawings

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.

WorkTypical 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.
