About Spanworks

Spanworks is a free planning tool for anyone thinking about a steel portal frame building: a workshop, warehouse, factory unit or farm building.

What it does

What it isn't

Spanworks is not a design or engineering service. Every building needs a structural engineer's design, planning permission where required and Building Regulations approval before work starts. Prices are indicative only.

Privacy

Your design is saved only in your own browser. Spanworks doesn't ask for your name or email.

Plan yours in 3D, free. Set the size, roof, cladding and doors, check it against the regulations and get a spec to send to suppliers.
