Insights

Short pieces written on the regulations, cost data and industry news that change what a scheme costs. We write them ourselves, and each one says what the change is worth in money.

WHAT WE WRITE ABOUT

We do not publish news for its own sake. Each piece exists because it changes a number in an estimate, and it says which number and by roughly how much.

  • Cost Watch. A short round-up of the numbers that moved, with what each one does to an estimate.

  • Regulation. Building Regulations, the Building Safety Act, planning obligations, and what they add per plot or per square metre.

  • Cost Data. BCIS and published indices set against what our own tenders are actually returning.

  • Comment. Our response to pieces in Building and the wider trade press, from the cost side.

A planning consent you cannot afford to build is the most expensive thing a developer can own

The order in which advice gets commissioned is largely a matter of habit. It is also, on a surprising number of schemes, the difference between a site that works and a site that sits.
