One thing before you open them.
The three guides you just bought tell you what to watch for on an extension and why it matters. That is the knowing half of the job. The other half is doing it, across a live project, week after week, at the moment each decision actually lands on your kitchen table. That second half is what the rest of this page is about, and it is the only time I will put it in front of you.
Knowing the pattern is not the same as having the tool in your hand
A project does not go wrong in theory. It goes wrong on a Tuesday.
It goes wrong when a builder asks for the next stage payment and you are not certain the stage is actually finished, and you pay because the alternative is an awkward conversation. It goes wrong when a change gets agreed in the garden, costs are mentioned but never written down, and the figure on the final invoice is one nobody remembers agreeing. It goes wrong when three builders send three quotes that priced three different scopes, and you have no clean way to compare them, so you pick on gut and price.
The guide tells you each of these is coming. Knowing it is coming helps. Having the exact tool in front of you at the moment it arrives, the payment-release check, the variation log, the like-for-like quote comparison, is what actually changes the outcome.
That tool, for every stage of the project, is the Toolkit.
The doing layer for the whole project
The Extension Project Toolkit is thirty-seven working tools that run the project from the first feasibility sketch to the final account when the builder hands you the keys. The calculators compute. The registers track. The scripts give you the words to use on the phone. Twenty-eight are print-and-use documents. Nine are working spreadsheets you fill in and that do the sums for you.
It follows the five stages of a real project, in order.
Stage 1 — Feasibility and Brief (7 tools).
Before you spend a pound on design. The Affordability and Budget Calculator that treats the first number as the floor, not the price. The Phasing Decision Planner, which is the one-application-or-several question turned into a worksheet (more on that below). A Go/No-Go gate so you know the project is real before you commit.
Stage 2 — Design and Approvals (8 tools).
The Council Call Script: the five-question reconnaissance call most homeowners never make. The Permitted-Development-versus-Application decision aid. An Approvals Register that tracks every parallel consent track and where each one stands.
Stage 3 — Procurement and Contract (8 tools).
The Tender Pack that makes every builder price the same scope, so the quotes are actually comparable. The Builder Vetting Checklist (insurance, registrations, the financial-health signs). The Party Wall Notice Planner. The Contract Terms Worksheet to work every term through before it reaches a solicitor.
Stage 4 — Build and Money (8 tools).
The Variation Order Log, live and running, so no change goes unpriced. The Payment Release Checklist that confirms a stage is genuinely complete before you release the money. The Decision Log, dated, that protects you from "you said."
Stage 5 — Completion and Handover (6 tools).
The room-by-room Snagging List. The Retention Release Checklist for the money you hold back. The Final Account Reconciliation: original price, plus agreed variations, equals what you actually owe, and not a pound more. The Resale-Readiness Pack that assembles the file you will be asked for when you sell.
The guides protect you from losses. The Toolkit does that too. But the place it earns its price is the move you would never have known was on the table.
A homeowner in Evesham had a large property and a long list of work, to be done in phases as funds allowed. He was advised, sensibly enough, to apply for the first phase, build it, and come back the next year for the next. So he did. £1,500 for the first set of plans, £600 in fees. The following year, £1,500 again, £600 again. £4,200 across two applications, on a project he believed he was managing carefully.
Nothing went wrong. Both applications passed. The work got done.
It is also a project where £1,600 of that spend was never necessary, and he never knew it. Planning law lets you put every phase of the work on a single application, even when you build them years apart, as long as you make a material start within three years. One comprehensive set of plans at £2,000 instead of £1,500 twice. One £600 fee instead of two. The later phases run on whatever timeline your money allows, with no second application ever needed.
He did not make that move because nobody in the room was paid to surface it. The builder's incentive was to get the first application in and start the job. The future phase was somebody else's problem. The question that would have saved £1,600, should this be one application or two?, was never asked, because he did not know it was a question.
The Phasing Decision Planner in this Toolkit is that exact question, turned into a worksheet you run before you commit to a single drawing.
On a modest Evesham-sized project, the play was worth £1,600. The same kind of move on a larger scheme is worth far more: a permitted-development route your designer did not think to take, planning history that supports a bigger scheme than you were going to ask for, a design decision that adds £80,000 to resale value instead of £20,000. The size of the play scales with the size of the project. That is why this is sold to people spending £30,000 to £150,000, and not to people fitting a rooflight.
£297 for the working file an architect's office would have run your project from
You already decided not to spend four to six thousand pounds on full architect's fees. That was a reasonable decision on a project this size, and the bundle exists because of it.
This is the operational half of that same decision. The guides gave you what an architect would have spotted. The Toolkit is the file an architect's office would have actually worked from: the calculators, the registers, the scripts, the trackers, stage by stage, for a fraction of the fee you chose not to pay.
Against a project costing £30,000 to £150,000, the arithmetic is not close. One avoided stage payment you should not have released. One variation that gets priced before you agree to it instead of after. One play surfaced before the drawings are paid for. Any single one of those returns the £297 several times over, and the Toolkit puts thirty-seven of them in your hands.
The same promise that came with your bundle covers the Toolkit. Work through it, and if you do not believe it has been worth at least £1,000 to your project, your money comes back. No claim form, no qualifying conditions, no fine print.
This is the one time I put the Toolkit in front of you as an add-on to your order. You can buy it later as a separate purchase, but the tools that save you the most, the budget calculator, the feasibility gate, the phasing planner, do their best work before the project starts. Added now, they shape the decisions still ahead of you. Added in month three, half of them are already behind you.
