This page brings together the data behind the Grand Reviews in one place.
Each chart is built from real projects, broken down into the numbers that actually matter when you’re thinking about a self-build. Cost per square metre, total spend, plot value, and how those figures compare across different builds and locations.
On their own, these numbers don’t mean much. But when you start to see them side by side, patterns begin to emerge. What a “typical” project looks like. Where costs start to drift. And where certain builds sit well outside the norm.
The aim isn’t to predict the future or give you exact answers. It’s to give you a reference point. Something to sense-check your own assumptions against.
If you’re looking at a plot, setting a budget, or trying to understand whether a project stacks up, this is where the data starts to give you context.
