The above basic price is just straight lay brick. If you are doing columns, that's a big adjustment up, and there's a big list of extras. As a rule, I figure $7/sf for brick when building a home, which translates to $1/brick for modular size and $9/sf for brick on a commercial project, $1.30/brick for modular size.otta add to this, even if it is specific to Georgia, as I think our costs are probably 90% of the national average, so add 10% and then adjust for your costs relative to the national average...or something like that :-).
