Before they bought the land

The one they bought, and what it had to clear first

The plot they did buy took three visits, seven questions and four things that did not add up. All four were answered before the offer went in, and the answers are still there.

What it is going to cost

226 lines, grouped the way the work is actually bought rather than the way an accountant would group it. It is a budget filled in from real prices, not an estimate we invented.

When each bit happens

206 tasks, built from the answers to about a dozen questions about the home. Most self-builders have never seen one of these. It is the thing that tells you the roof cannot start until the scaffold is up, and what it costs you when the scaffold is late.

Asking several people the same question

22 enquiries went out on this build, across 19 packages. Each one carries a written schedule of exactly what is being priced, so the prices that come back are about the same job.

This is the one thing on the page we do not hand over. The schedules are ours rather than this build’s, and they read the same whoever is using them, and they are most of what you are paying for.

One page of an enquiry’s pricing schedule for the masonry shell: a sample panel, setting out, damp proof course, both leaves, the cavity, closers and trays, each a line to price.

What came back, side by side

Piling on this build: 35 priced lines, three contractors. The sheet reads their quotes and puts them in the same rows, so what one of them left out is a gap you can see instead of a surprise in month nine. There are six of these on the build and the biggest ran to 66 lines.

What was actually agreed

42 orders and 9 appointments, each one a document with a date on it. When somebody says that was never in my price, this is the piece of paper that answers.

The instructions on this build: what changed, under which agreement, how it was priced, and when it was raised, priced and agreed.

What happened, day by day

205 days recorded: the weather, who was there, what was found. Photographs carry where they were taken, which is the detail that matters to whoever opens a wall in fifteen years.

One day in the site diary: what happened, recorded on the day.

Keeping people safe, and proving you did

23 method statements read and checked, a construction phase plan, a waste plan, and the registers an inspector asks for. We do not write your method statements. We read the ones you are handed and tell you what is missing from them.

A method statement checked: what to put back to the contractor, each point with the reason and the question to ask.

How it is going, on one screen

Budget, buying, programme, safety and consents, each marked green, orange or red, with the line that made it so. It is the first thing you see when you open the build, and it tells you what needs you next.

The dashboard: budget, procurement, programme, health and safety and consents, each marked good, caution or problem, with the lines behind the mark.

One file, at the end

Everything above, plus the certificates, the warranties, the drawings and the photographs, in one archive with a contents page somebody else can follow. You keep it whether you stay subscribed or not.

The completion shelves: one for the building control certificate, the warranty and its policy documents, and each certificate a finished build needs.

The part we cannot show you

The record pays out on a day you cannot schedule. It is the morning somebody tells you the connection was never in their price, or the year your solicitor asks for a certificate you last saw in an email two years ago. Nothing on a web page can demonstrate that, because it takes two years to happen and it happens once.

What we can show you is that the answer would be here. Every document above is filed against the day it arrived and the thing it belongs to, and it stays there.

That was somebody else’s build.

Seven days on yours, with everything unlocked.
