Most WikiHouse files and information are licensed under a Creative Commons–Sharealike licence, so you are free to use, distribute or modify them, including commercially.
All WikiHouse information is shared 'as is', without warranties or guarantees of any kind. You are responsible for checking it and using it in a safe and responsible way, for example, getting it checked by a structural engineer.
You are responsible for making sure your project complies with all relevant local regulations, including planning, building codes and health & safety legislation. If in doubt, seek professional advice.
If you make any improvements to the system, you must publish your files under the same type of open licence. However, you do not need to publish the plans and specifications for individual projects unless you wish to.
We strongly recommend using an approved WikiHouse Manufacturer to make your WikiHouse blocks. If a CNC fabricator you want to use is not yet a WikiHouse Manufacturer, you can put them in touch with us and we will work with them to ensure your chasiss and blocks are made to proper production standards.
We provide a range of support services and tools to make it easy to deliver your project using WikiHouse, including a full chassis design and check service. It is not compulsory to use these, but it is recommended.
Do not use the name "WikiHouse" to name or describe your company, organisation or any marketed product or service unless your blocks have been made by an approved WikiHouse Manufacturer or you are a WikiHouse Partner, in which case you may use the WikiHouse trademark under the terms of that agreement.
Do not remove any licence notices from files if you are re-sharing them.
Do not give the impression that you are endorsed by, or affiliated with WikiHouse or Open Systems Lab (unless you are, by written agreement), and do not claim to represent the WikiHouse project or community as a whole.
