The my incredible house series is produced by Xella. It shows how easy it is to build your own Ytong house under the guidance of a Ytong master builder. While we do not offer these specific build services in New Zealand due to our building regulations, the video is very informative.
Using a double bladed saw or handheld manual router and slots cut for electrical conduit.
Plumbing from ceiling
Wate pipes are positioned and held within the slot prior to being plastered over.
Main power to house
The power cable has been taken through the foundation and into the garage. An insert created ready for the power metre box.
Power and service cables are laid in the foundation. The 1st and 2nd course of blocks had holes drilled. Cables were pulled through.
Preparation of foundation
Before the first course of blocks is laid stubs are chem set into foundation, mull seal is applied and blocks are cut out as required. Note also plumbing services are already in place through the foundation.
Steel stub in first course
As the wall is constructed the block in each course above the steel stub a 50mm hole is drilled vertically using a wooden jig. Note the vertical pencil mark on the second course block for alignment.
Steel connector in first course
Once the wall is complete a steel rod is inserted from the top down and connected as shown. The hole is later filled with grout once the numbered wedge has been replaced and set in place with Ytong adhesive.
Bond beam is ready to pour
The bond beam is made from 50mm Ytong panels glued to the wall forming a U shape. All steel has been laid and connected to the vertical rod running through the wall from foundation to top plate.
Completed bond beam
The external wall is topped all round with a bond beam filled with concrete. Note also the internal wall construction using 150mm wide block
Top plate is fixed to wall
Once the wall is complete to the correct height the top plate is fitted and then locked in place. The wing nuts connect the steel rebar which runs from the foundation vertically through the wall to the top plate. This ties the whole wall construction together from foundation to top plate. Roof trusses can now be fitted.

Wooden top plates and vertical side plates are attached to the wall.
