FAQs (Trainers, questions & answers to STEP Training)


Musterelemente auf der Virtuellen Baustelle in RavelsbachUnit 1: Introduction in Straw Bale Building

We start with a general introduction into history and status-quo of Straw Bale Building. there is a lot to learn about the building material (straw bales) itself: Procurement, production, quality assessment, testing, handling, storage … The tools are presented and partly self-made (stuffers).

Theory & Practice: € 250,–/Person; € 180,– for Students
Partner-price: Your partner just pays the reduced students-price!

Language: English/German


Unit 2: Straw Bale-Infill, CUT-Technique, Prefab

We get to know the different wood frame construction methods: Wooden constructions (CUT in the middle, CUT supporting planking, double post) are infilled with straw bales without gaps (infill = filling in), prefabricated wooden straw components (modules) assembled professionally. Bales are cut, tied and / or efficiently compressed in the walls. In the practical workshop, a detached house in timber frame construction is filled with straw bales and then (in the second half) plastered with clay (and lime). We show how windows are sealed with flax and sealing tapes, how electrical cables are laid in straw bale walls and how details are executed correctly.

Theory & Practice: € 580,–/Person; € 370,– for Students
Partner-price: Your partner just pays the reduced students-price!

Unit 3: Load-bearing straw bale building

The initial straw building does not need any supporting construction for walls, the straw bales alone are „load-bearing“. Wood is used for protection and support (base plate, roof assembly, window frames), structural integrity (ring beam) as well as for additional construction. In theory, we handle the preparation and selection of the right bales, statics, the construction schedule and construction of load-bearing straw bale houses. In the practical workshop, a building with small bales is built load-bearing and plastered.

Theory & Practice: € 670,–/Person; € 610,– for Students

Unit 4: Wrapping – External Straw Insulation

In „wrapping“ buildings are all around covered with straw bales. We show wrapping possibilities for insulation thicknesses from 15 cm with diagonal bracing, pallets, slats and facade panels. We learn how to make an additional foundation and set up an auxiliary construction, as well as the professional attachment and the complete, windproof design.
In the practical workshops, a barn and „Fachwerkhaus“ is restored and wrapped (inside) with straw bales and plastered with clay, for fixation we assemble a CUT hybrid construction.

Theory & Practice: € 490,–/Person; € 310,– for Students
Partner-price: Your partner just pays the reduced students-price!

Language: English/German

Unit 5: Finishes (Clay-, Lime Plasters, Wood Cladding)

Only the most meticulously designed surfaces prevent structural damage in the long term, especially in diffusion open building construction. Material knowledge (clay, lime plaster), as well as a lot of practice from base plaster to fine plaster, characterize this unit.
In the practical workshop, we plaster with clay (earth) and lime, manual plastering is shown as well as spray plaster.

Theory & Practice: € 820,–/Person; € 720,– for Students

bauphysikUnit 6: Building Physics & Sustainability

The knowledge of the building physical properties of building materials is an indispensable basis for their optimal use. It is thermal bridges, mould, moisture (condensation) … to recognize and avoid. We treat the subjects of thermal insulation, fire protection, sound insulation, moisture protection and heating and calculate and optimize straw construction according to their required properties. We show how sustainability, wellbeing and a healthy indoor climate can be implemented in a straw bale house.

Theory & Practice: € 460,–/Person; € 270,– for Students
Partner-price: Your partner just pays the reduced students-price!

Extra Unit Solar Energy Autarky, Virtual Building Site Ravelsbach/NÖ
Topics: DIY-Solar Cooker, Solar Can-Ventilation, Storage Ovens, Pizza Ovens, Photovoltaics,…

Theory & Practice: € 250,–/Person; € 180,– for Students
Partner-price: Your partner just pays the reduced students-price!

Language: English/German


Unit 7: Solar Architecture, Design, Installation, Cost Calculation

The principle of „straw construction“: You learn to read plans and to implement construction plans and learn how construction, insulation, electrics, water, building services and heating … interact. With a straw construction overview, you prevent building defects and repair building damage and keep the budget within limits. We also show how organic straw bale building is possible and how to save on building costs. With practical workshop planning of a straw bale house, videos and discussions.

Theory & Practice: € 460,–/Person; € 270,– for Students

marketing-kommunikationUnit 8: Communication & Marketing

Market knowledge improves your bargaining position, knowledge of suppliers and prices enables costing. We show (open-source) tools and software for self-presentation (CI), administration and successful (social media) appearance. The basis of everything is communication and knowledge about target groups, other craftsmen (networking) and suppliers (where can I get what?). We show how the price of a straw bale house can be estimated, calculated and communicated. And explain the differences between soft and hard costs and show savings.

Theory: € 280,–/Person; € 180,– for Students
