Build the footing and insert rebar into the wet concrete at intervals corresponding to the cores in the blocks.
The length of the 824 assembly if available provides the flexibility to make this block ideal for this application.
The ground from the bottom to the top is about 6 feet with a length of 22 feet curving around the house.
A retaining wall integrated into a sloping front lawn adds polish and curbside appeal.
Avoid having downspouts pointed at the retaining wall and if it s against the house keep soil and mulch well below the siding.

Stack the second course of blocks on top of the first course making sure they remain level.
If using the 812 assembly use the instructions listed above.
I am going to put in about 6 terraces to allow for the slope and am making each section about 12 inches high to allow for clearance with the siding on the house.
