ICF Designer

Design an ICF home. Know what it will take to build.

ICF Designer turns a concept layout into ICF-specific quantities: blocks, concrete, reinforcing steel, labour, waste and budget forecasts, so you can test ideas and make informed decisions early.

What the engine produces

Every number traces back to the geometry

This is not a PDF tool, a budget spreadsheet, or a project-management add-on. It is an ICF-aware analysis engine — and these are its outputs.

ICF block layout optimisation
Optimisation

Lay out the build the way ICF is actually built

The layout resolves block coursing, corners, openings and offcuts automatically, so the model reflects real construction instead of a rough allowance.

  • Full-module optimisation that minimises cuts and waste
  • Corners, gables, mono-pitch and openings handled as ICF conditions
  • Offcuts tracked for reuse across walls
Project quantities take-off
Quantities

A take-off that comes from the model, not a guess

Blocks, concrete volumes, reinforcing steel and waste are generated from the same geometry — so the numbers stay consistent as the design changes.

  • Bar-by-bar reinforcing schedules, not just total weights
  • Concrete volumes per wall and overall
  • Waste quantified instead of assumed
Labour estimate from the ICF model
Labour & cost

Labour and cost follow the same source of truth

Because labour and budget are derived from the optimised model, the cost you see at concept stage is the cost you can defend — and revisit every time the design moves.

  • Labour effort estimated from real quantities
  • Live budget that updates as you design
  • Costs in your own currency
One message, two starting points

Wherever you start, the answer comes from the model

The engine is the same. Pick the door that sounds like you.

Homeowners & owner-builders

"Can I afford to build this in ICF?"

Test a concept before you commit to a design. See blocks, concrete, steel, labour and budget early — while changes are still free.

Builders & contractors

"Can I quote and build this accurately?"

Build a take-off from real geometry. Protect margin with explainable quantities, then carry them downstream to ordering and exports.

Build a trusted take-off →
Reinforcement inspection view explaining how quantities are derived
Trust

An estimate you can challenge, adjust and trust

Every headline number is backed by the model. Inspection views show how bars, laps, openings and quantities were derived — so an early estimate can be questioned and verified rather than taken on faith. Confidence comes from traceability.

When the concept becomes a project

Budgets, contractor ordering, PDF schedules and IFC exports are downstream outputs — they exist because the quantities are already trusted. Project management arrives when you need it, not before.

Example Cost Analysis Outputs

Outputs are useful because the quantities are already tied back to ICF geometry.
