The 20 Stages of a Build

  1. Clear site
  2. Mark out footings
  3. Dig footings
  4. Remove excavated soil.
    N.B. soil removal has a big cost so ensure this gets done early on within your costings. Also means builders aren’t having to work around soil and lends itself to keeping a tidy site
  5. Pour concrete
  6. Engineer the build out of the ground to damp course level
  7. Oversite (100mm type 1, DPC, 100mm concrete)
  8. Build – These three go up together to wall plate level:
    a. Brickwork
    b. Cavity Insulation
    c. Blockwork
    N.B. Scaffolding should get erected at about half way height. Any required steels go in during brick build, before wall plate.
  9. Roof timbers & joists
  10. Soffits and fascias
  11. Felt, baton & tile roof. Leadwork then required here where any new building joins to an old/existing building to waterproof and protect.
  12. External doors and windows installed
  13. If building an extension, this is usually the point where I’d knock through to the existing building as minimises disruption to the customer until now.
  14. Flooring
    a. Floor insulation
    b. Under floor heating installed now if relevant
    c. Screeding
    N.B. Before screeding you must have decided what floor finish you want as there are different screeding allowances depending on the floor product you choose (tiles, wood etc…)
  15. Internal stud work & door frames where required
  16. First fix – get the electric cables and plumbing pipework in place
  17. Drylining. Either:
    a. Plasterboard, tape and join or
    b. Plasterboard and skim
    N.B. The costs of either option are pretty much the same but my personal preference is for tape & join. This is because you can paint immediately, whilst if you skim this will require a week to dry out so extends the build time. Of course, if you have curves to factor in, then skimming will be required – just ensure you have a good plasterer to get a smooth skim finish.
  18. Skirting and architrave
  19. This is the point where you should work through a snagging list with your builder
  20. Second fix electrics and plumbing – this is when the electrics and plumbing are finished – all pipework and cables are attached to something (!): extractor fans installed, sockets, plug switches, light fittings, appliances installed, baths/sinks/toilets fully connected and operational
