Small new build (single dwelling, outbuilding): cost a whole project, stage by stage

The whole stage ladder; most stages call a recipe, the rest are quotations. JobBosh lays the project out as 23 stages: 0 are calculated by their own recipes from your measurements; the rest - design, steel, windows, certificates - are priced from a quotation or a figure you already hold, and it says so until you have it.

What you get

  • Every stage's quantities and hours from its recipe, priced at your rates and prices; the specialist stages as named unknowns until a quotation or your figure resolves them - never a guess
  • Supplier enquiries drafted from the job's facts for scaffold, skips, steel, windows, the professions - approved by you before anything is sent, replies compared like for like
  • Travel, parking and road charges from the dated catalogue; the site questions (welfare, power, water, access, protection, waste) as lines, enquiries and sentences in the document
  • A phased, branded quotation itemised by stage that reconciles to the penny, with provisional allowances shown apart, accepted on a secure link; variations recorded against it
