From Rob Harris — Registered Architect, 25 years

The most expensive part of a renovation
is the part nobody warns you about.

It's not the kitchen or the extension. It's the avoidable mistakes — the hidden costs, the wrong order, the builder traps. I've spent 25 years sitting at kitchen tables watching good people lose tens of thousands to things that were completely preventable. So I put everything I do into one system, step by step, so you don't have to learn it the expensive way.

What it actually costs

Most of these mistakes look small.
They're not.

After 25 years I see the same ones over and over — and none of them are bad luck. They happen because no one told the homeowner the step, or the question, before it was too late. Here's what I've watched them cost.

$8,000+Concept drawings that never get built — wrong brief, wrong order.
$14,000A retrospective permit on a $1,400 job, found years later.
$30,000The emergency shortfall when the bank won't lend a cent more.
$23,000Undocumented variations you can't dispute once the work's done.
