I use Google Sheets with my own formulas for quantifying , and Sketchup for the 3d and virtual building work. I export the data from sketchup into Sheets to give me my exact quantities and add wastage.
Thks for the replay much appreciated, I will be doing a shelf build next year and I will use you information and videos, absolutely 💯 brilliant tks 👏 👌
Hi. Not sure exactly the bit you mean but…for an attic extension in the uk, you’re going to have to apply for a building warrant or building regulations approval. You will therefore require a structural engineer to complete the calculations for your timber / steel sizes and they provide a certificate which you submit. Hope I’ve answered your question.
I’ve allowed sole trade rates for all these guys, so it’s a bit swings and roundabouts . If you use a main contractor you might pay more because of the vat element , but conversely the main contractor will have core employees, for example, labourers , brickie builders, joiners etc on main contractor’s payroll, will not be paid close to the rates I have allowed here. However, where they are not employees, for example, plumbers / roofers / electricians will probably be sub contracted, and they’ll add between 10 and 20pc on top of those. Same for some, but not all, materials. You’ll be paying for his coordinating , site insurance, vans and admin overheads which is what the mark up covers.

Useful, thank you so much. Am i right in assuming these prices are if you manage it yourself?
