I helped build a 4 bedroom Straw Bale House in the Riverina in 2011.
The cost of the build was just $180,000.
Smooth wall and sharp corner rendering.
Insulation 80% superior to a double brick veneer.
Sound proofing 72% with outer room as owner's jam music room.
Took 79% less time to build than conventional builds.
That means less cost on hourly rates.
Walls are fire 🔥 proof.
Earthquake? The walls and structure wobble, not crumble.
How do you stop a Straw Bale House from rotting?
AI Overview
To stop a straw bale house from rotting,
you must keep moisture out by using a high foundation,
wide roof overhangs, and breathable natural plasters.
Key Prevention Methods
Elevate the foundation:
Build your walls high off the ground on a concrete slab or raised footing to block rising damp and ground water.
Use wide roof eaves:
Install deep roof overhangs to shield the exterior walls from direct rain and heavy downpours.
Apply breathable renders:
Cover the bales in lime or earthen plaster instead of cement. Cement traps moisture inside, while breathable lime and earth allow trapped humidity to escape safely.
Check bale moisture levels:
Ensure straw is completely dry (below 15% moisture content) before stacking and rendering.
Use a moisture meter to test deep inside the bales during construction.
Fix damage quickly:
