Build a realistic structure budget.

In three short steps, estimate structural walls, floors, quantities, and labor — without pretending to be a structural design.

Structure Calculator estimates external and internal load-bearing walls, structural floors, typical allowances, and erection labor.

Structure Calculator estimates external and internal load-bearing walls, structural floors, typical allowances, and erection labor.

Masonry or timber?

Technology, geometry, openings, and local rates move the result. The range helps you prepare better first conversations with contractors.

Included

external structural walls, internal load-bearing walls, structural floor system, typical structural allowances, erection and labor

Excluded

foundations, roof structure, windows and doors, thermal insulation, facade, installations, and finishes

Frequently asked questions+
Is this a structural design?

No. It is a budget estimate; structural design belongs to a qualified designer.

Is roof framing included?

No. Roof framing is outside the Structure Calculator scope.

Is the timber quantity an order list?

No. Final framing takeoff must follow construction documents.

Are foundations included?

No. Foundation is a separate stage and is excluded.

This calculator does not design structures, select member sizes, or calculate capacity. It does not replace construction documents. Roof framing and foundations are excluded.

How it works

Set the area, storeys, shape, opening intensity and structural system. The model uses budget geometry, material quantities and separate labor to show a planning range.

What affects the result

Wall or frame system, wall material, floor system, storeys, shape and openings affect structural area and installation effort. Timber quantities are budget quantities, not an order list.

What is included

The scope includes structural external and load-bearing internal walls, structural floors, typical allowances and erection work.

What is not included

Foundations, roof framing, facade, insulation, openings, services and finishing are outside this calculator. It does not design member sizes, reinforcement or load paths.

How to use the estimate

Compare systems on like-for-like assumptions, then pair the result with foundation and envelope budgets to check the boundaries between trades.
