Reinforced concrete design, checked against the clause.

Structural Studio makes design spreadsheets for engineers who need to show their working — built to one code, end to end, with every check traceable back to the clause it comes from.

What we do

Design aids you can actually check.

Most spreadsheets that circulate in a design office are locked, undocumented, or quietly out of date. Ours are the opposite: plain workbooks you can read, verify and hand to a checker without writing a separate calculation note.

Written to one code

Each pack follows a single code from first principles — not a sheet with the units swapped. Inputs are laid out the way the code lays them out, so the logic is easy to follow.

Open by default

Plain formulas throughout. No macros, no password-locked cells, no hidden sheets. If you do not trust a number, you can trace it back to its inputs.

Checked before it ships

Every sheet is hand-verified against worked examples before release, and every line carries the clause or section it comes from in the margin.

The packs

Two codes, the same set of elements.

Beams, columns, slabs and footings in both — sold separately, licensed per user, unlimited projects.

How it works

From purchase to first check.

01

Buy the pack you need

Choose Eurocode 2, ACI 318, or both. Checkout is handled by Lemon Squeezy and the file arrives by email — no account required.

02

Open it in Excel

Every sheet is plain formulas, no macros and no password locks — read every calculation before you trust it.

03

Enter your section and loads

Fill the input cells and the sheet runs the full check set, flagging anything that does not pass.
