OP, this may not be as simple as cutting hole and sticking in a window. You may need to have a concrete (or equivalent) header installed to support the roof, the house plans will be useful to determine this. Wiring should not be a problem, dust will be. I am not familiar with the building code, but our Gardenia appears to have the concrete block filled with concrete in the vicinity of window and door openings as well as a few other places. The Sumter County Building Department, in Pinellas Plaza can provide ypou will your house plans, and as noted above, call ARC first and submit plans for approval.
