Costing

Reinforced concrete wall

3 man days x $150 = $450

Materials = $2110

Total $2560

Wood wall

2 man days x $150 = $300

Materials = $2570

Total $2870

Although the block wall took longer, it is 10% cheaper than using wood.

Even using 2”x 4” and no insulation it is still more expensive building in wood if no rebar was used in the block wall.

Block is cheaper, stronger and cooler so why build in wood?
