StairDesigner 7 Special Offer

We will be launching the new version of StairDesigner, version 7, in the near future. It is being rewritten from the ground up, complete with many new features for even faster and more accurate design and manufacture.

Although we are still adding functionality, it is now available as a BETA release, COMPLETELY FREE OF CHARGE when you buy version 6.

All future upgrades to version 7 will then be free of charge. This means you will not have to pay to upgrade to version 7 after the official launch.

This offer is only available until the launch of version 7 in the near future.

Please note that version 7 is a completely new program. The file format is not compatible with version 6. You can work either in version 6 or 7. Version 6 projects cannot be opened with version 7.

Please contact us if you have any queries or would like an online demonstration.
