STEP – Straw Bale Building Training for European Professionals – is a professional straw bale building training in theory and practice according to ECVET. Languages of instruction are German and English. The training is divided into 8 online theory modules and 4 practical modules, you can do the STEP Training ONLINE by yourself, participate in the Workshops in the Training Centre (in Austria and/or Portugal) and on Building Site Practical Workshops. So you have maximum flexibility: learn what you need and when you can.


Being a Certified Straw Bale Builder opens up many exciting opportunities for you:

You could become a craftsman specialising in sustainable building. Companies like StrohNatur, as well as carpenters who want to expand their sustainable portfolio, would love to have you on their team. The first step as a STEPper may be complicated, but you have the full support of the asbn and ESBA networks in Europe. If you want to work in this sector, there are usually plenty of jobs available all over Europe.

Great straw building projects are waiting for passionate builders, planners and trainers. In many European countries, there is not only a need to renovate and optimise the existing building stock, but also a huge demand for social housing. Eco-resorts, hotels and shopping centres are also offering an increasingly sustainable lifestyle to a growing number of people looking for alternatives.

Rebuilding houses destroyed by war, floods or forest fires is one of the biggest challenges, and not just in disaster areas. The number of houses in Ukraine alone (Europe’s largest supplier of grain such as wheat) is staggering. ESBA has started a programme with Ukrainian non-profit organisations such as FIABCI (Rebuild Ukraine) to organise these future tasks.

And if you are thinking about building your own home, whether it is a new house in a rural village or a renovation of an existing building, STEP will help you avoid mistakes, save money and participate in the building process – as a designer, builder or simply as a better quality-controller.

You see, this amazing technique for building or renovating affordable, sustainable and healthy homes is your opportunity for a long and enjoyable career for the future and one of the best answers to climate change.

You may be wondering what you can do with your STEP certificate when you graduate. No, it is not a licence to build houses completely on your own (you will need someone to take responsibility for the structural and energetic quality), but you will be able to work as a straw bale builder or construction designer or as a builder in a team (with at least one master carpenter, master builder or structural engineer), as a trainer (offering workshops or help to owner-builders) or as a start-up (could be an association like asbn or a small company like KG, OEG or GmbH).

STEP will help you to select and calculate the right materials and techniques, to make the right decisions in difficult situations, to have the skills to carry out the tasks such as straw bale filling, prefabricated modules, wrapping, plastering/rendering and decorative finishes. You will be able to construct small timber structures (CUT or hybrid structures, double post walls or wrapping structures), make a house windproof and airtight (including plumbing and electrical wiring in straw bale walls). Most importantly, you will be able to choose the most affordable and sustainable technique or solution for building a healthy living space.

THEORY UNITS (with introductory practice) at the Virtual Construction Site in Ravelsbach or Online

Everything you need in terms of knowledge (competence) to build a solid, sustainable, long-lasting straw bale house and to avoid mistakes. The theory modules – except for the STEP 5 – FINISHES module (at the Virtual Construction Site in Ravelsbach in Lower Austria in summer) – can be attended as ONLINE or on-site-workshops from January to March in Portugal (in winter) at the training centre on fixed dates. You will learn all 8 modules on our ACTeco learning platform with numerous presentation videos or directly in life presentations in the training centre. All theory days (8 hours each) are entered in your theory certificate. As soon as you have completed all 8 modules, you can take the final exam (written and oral).

PRACTICAL UNITS (on real Straw Bale Building-Sites)

To become a certified straw bale professional, you need proof of at least 20 completed STEP practical days in addition to the theory. The practical exam is integrated into the training. All practical days (8 hours each) are entered in your practical certificate. You can arrange these individually according to your time budget and the availability of practical workshops. You can also do the practice spread over 2 or more years.

The practice workshops cannot be held online. You can book the practice modules as soon as they are offered on, but we have to postpone or cancel them if they cannot take place with at least 5 participants.
