Build Cost Intelligence · Extend or Move
Extend, or move? The answer is in the numbers.
The biggest decision you will make on your home should not run on guesswork. We set the true cost of staying and extending against the true cost of selling and moving — so you decide on the numbers, not a hunch.
The question it answers
“Should I extend, or move?”
Outgrowing the house, and unsure whether to build on or trade up. Extend or Move puts the two costs side by side — what it takes to add the space where you are, against what it costs to buy it elsewhere — and tells you which comes out ahead.
Where it sits
The smallest report. The largest decision.
At £49 this is the place to start — a fast, two-page comparison before you commit to either path. If it points you towards building, the detailed cost reports take it from there.
A desktop comparison, not a survey or a valuation — but every figure in it is built from real cost and market data.

The cost to extend
An estimated build cost for the work you have in mind, calibrated to your area.

The verdict
Which option costs less, and by how much — stated plainly.
