WikiHouse Blackbird can work with any foundation type, provided they are constructed with sufficient accuracy or can be adjusted. It can also work on sloping sites. You will need a structural engineer to design the foundations for your site (we may be able to help you find one).  It is a strongly advisable to have foundations and service connection points installed in advance.

The materials are guaranteed for 60 years, which is the minimum design life for new homes, but if kept dry and safe from insect attack, there is no reason why a WikiHouse structure should not last much longer than this. Timber frame houses are extremely robust and can even last for centuries.

Yes, certainly in the UK. Most building control officers will treat WikiHouse like any other timber frame structure. However they will require a structural engineer to sign-off the design. Please note that regulations vary from country to country.

The cost always depends on your design, specification and how much work you do for yourself. We believe in making costs transparent so you can make informed decisions. In most areas, overall cost will be similar to other building methods, but the building will be faster and easier to build, more customisable, more sustainable and higher performance. The cost will also be much more predictable, especially as the cost and risk of conventional construction is rising all the time. 

Yes, although this adds an additional cost to your project, to pay for a Warranty (10 year defects liability insurance), which is what most mortgage lenders require.

Yes, and it’s a lot of fun. But it’s important you do so in a competent, safe way, and comply with any relevant health & safety regulations and insurance obligations. By breaking the project down into discrete tasks, it becomes much easier to choose how much work you do for yourself or pay others to do.

No, however we have a growing network of approved designers, engineers, manufacturers and assembly companies who can help you realise your project. We also provide a range of additional services for design teams. Get in touch with us, let us know about your project and we’ll do our best to connect you with the support you need.

At the moment we are not yet ready to certify accredited suppliers or partner providers, however we do plan to do so in future. In the meantime please go ahead and develop your experience in using the WikiHouse system. You can register your interest here and we will get back to you when we do start a partner providers programme. In the meantime you can of course tell your clients that you are using the WikiHouse system, but please do not say that you are an approved or official supplier, or advertise yourself or your product using the tradename WikiHouse. Read the full WikiHouse terms of use here.

Yes. WikiHouse is open source technology, developed by a community of designers and engineers. So you can use the intellectual property for free without asking our permission. We believe sustainable building solutions should be common knowledge for everyone. However you must share any improvements you make under the same licence. You cannot sell any product or service using the name 'WikiHouse' without our express permission. Most importantly of all, WikiHouse files and information come with no warranties or guarantees, so if you do use them, you do so entirely at your own risk. Read the full terms of use here.

There are lots of ways you can contribute your time and expertise. Check out the list of open challenges on the contributors page here. You can also help support the project by donating, this will keep the project going and support ongoing open R&D.
