Half height retaining wall. This is where the stairs from upstairs come down.

Temporary staircase.

This section needs to come out. A non-retaining wall will support the external wall here.

The concrete beam can be supported directly on the rock 1m below ground level. There is rock at half this depth but at 1m the rock is much stronger.

Rebar for the beam.

Beam poured but at 100x380x260mm it is more of a block then a beam!

Shuttering removed and behold, a beautiful beam. I'm getting the hang of pouring concrete.

Funny shaped wall to support the external wall across the section without retaining walls. i.e. the part where there isn't a basement.
