The long read
The decision you make before you know you are making it
Most budgets are not lost on site. They are lost in a kitchen conversation months earlier, when nobody writes down what the project is actually for.

Ask a homeowner when their project began and they will usually name the day the scaffold went up. Ask their builder and they will name the day the drawings arrived. Both are wrong by about a year.
The project began in a conversation nobody recorded: someone said the back of the house does not work, someone else said you could open it up, and from that moment every drawing, quote and argument descended from an idea that was never written down.
This is not a soft point about intentions. It is the most expensive mechanism in domestic construction. An unwritten brief cannot be tested, so it is tested for the first time by a price — usually a price that is forty per cent above what anyone had in mind.
“A brief is not a document. It is the shortest sentence that lets someone tell you that you cannot afford it.”
Why the first page is the cheapest page
Every later decision on a project is a comparison. Is this quote reasonable? Is this variation necessary? Should we spend the contingency here or keep it? Comparisons need something to compare against, and on most projects that reference does not exist. So the reference becomes the last number anyone said out loud, which is usually the most optimistic one.
Writing three sentences — what is wrong with the house now, what must be true when the work is finished, and who it is for — costs an evening. Not writing them costs, on the projects we see, somewhere between eight and fifteen per cent of the build value in redesign, re-pricing and changes of mind after work has started.
The discipline is in the shortness. If you cannot say what is wrong in two sentences, you are describing a wish, and a designer will fill the gap with their own idea of what you meant. That idea will be good. It may also be a storey taller than your budget.
The three-sentence brief
- What does not work about the house today, in plain words
- What must be true on the day the builders leave
- Who this is for, and how long you intend to stay
- Three things you will not compromise on — and three you would give up
The order of decisions matters more than the quality of any one of them
There is a running order to a building project, and it is unforgiving. Brief before design. Design before pricing. Pricing before commitment. Commitment before demolition. Almost every crisis we are asked about is a project that ran those steps out of order and is now paying to run one of them twice.
The most common inversion is pricing before design. A homeowner with a sketch asks three builders what it would cost. They receive three numbers that are not comparable, choose the friendliest one, and discover during the groundworks that the steel was never designed, so it was never priced.
The second most common is commitment before pricing: a start date agreed and a deposit paid while the scope is still a conversation. From that moment, every clarification is a negotiation you enter from behind.
How to tell whether your project has a brief
There is a simple test. Send one page to your architect, your builder and your partner, and ask each of them to tell you, without discussing it first, what the project is for and what must not be sacrificed. If the three answers do not match, you do not have a brief. You have three projects being drawn as one.
This is not an exercise in bureaucracy. It is the cheapest form of risk control available to a homeowner, and it is the only one that does not require you to know anything about construction.
The last word
Write the three sentences this week and date the page. Send it to everyone advising you and ask them to reply with what they think it means.
Where the answers differ, you have found the part of your project that has not been decided yet — before it costs anything to decide it.
