About us
We’re developers,
helping developers.
In a world of rising costs and shrinking margins, the detail in the numbers has never been more critical.
Laura’s background
Never underestimate the power of 1% at scale.
Tesco · merchandise planner
Running a £50m department tracked line by line, entirely in Excel. At that scale, 1% is £500,000 — and finding it, or losing it, came down to the small numbers hidden in stock, availability and promotions.
Sparesbox · Head of Growth · Sydney, Australia
She took that discipline from launch to exit — the same instinct, applied to a startup where nothing could be wasted.
Her own £1.2m build
Then she put her own money where the spreadsheet was. On your own build, 1% isn’t a line on someone else’s dashboard. It’s twelve grand of your margin.
And most developers aren’t losing 1%. They’re losing far more.
The honest ledger
We counted exactly where ours went.
That 1% lesson got expensive on our own build. This is the post-mortem most developers run in their head at 2am — except backed by the real site records.
The build, start to finish
The site
A tight plot with overhead cables meant no crane and every delivery by hand — and with soil tests late, procurement stalled before a spade had even hit the ground.
The ground
Heavy clay and a high water table fought every pile — then a month’s rain collapsed the open trenches, and re-sequencing the whole programme by hand hurt more than the re-dig.
Frame & fit-out
Fourteen trades stacked into the same rooms, changes flying around unmanaged — and every idle day, the finance kept carrying interest for nothing.
Finishing
Render on, the driveway going in — the build all but done. But by now the paperwork had fallen behind the bricks.
The result
It finished beautifully, but paperwork backlogs held up sign-off — so we missed the peak selling window entirely.
The first part is development — you can’t take the weather off the board. The second part is admin — and that, you can.
Build vs buy
Building it yourself feels like the safe, efficient choice. It’s neither.
Owning the code feels like control. In practice it’s a permanent cost and a single point of failure — and it pulls your best people off building.
On your own
With BankBuild
It breaks every time a tool or a lender changes.
Updates are handled for you, automatically.
A bill that never stops — engineers, retainers, fixes.

One system, one team: a single point of failure.
One hardened core, watched 24/7 and kept in the UK.
Developers and lenders
Whatever the stage. Whatever the size.
We run the admin layer for everyone in a development, from a first project to a full pipeline, with no need to change how you already work.
